The Day After the Holiday: Flying Home Safely

November 30th, 2015 by Amy Laboda

The day before a holiday, given there are blue skies, is a silly, noisy day in the airpark. People are on the move. My pilot neighbors who have decided to fly to family are loading up and heading out, sometimes en masse, wisely using their aircraft to avoid what can be dangerously packed highways of travelers, and miserably packed commercial airline flights.

Funny, I don’t worry so much about them on the day they leave out of here. The day after the holiday, though, I admit to fretting a little. Why? Statistics.

Weather is the great delineator on the flight home after a holiday.

Weather is the great delineator on the flight home after a holiday.

It is much easier to decide to stay home for the holidays when you are still in your driveway, contemplating the weather, than it

is to imagine staying on at Aunt Fran’s or Grandma’s, where you may be packed into an expensive hotel room, or maybe the basement spare bedroom (probably no wifi down there, either). The NTSB annals are full of accidents and incidents that happen on the backside of the holiday curve, when people are saturated with food, family, good times, and sometimes rushing to get back for work, school or other ordinary pressures. Suddenly pilots everywhere feel that pinch at the base of the neck and catch themselves almost universally thinking, “Well, maybe the weather isn’t really that bad. Maybe the ice won’t be there, maybe the thunderstorms will drift off the route… and maybe the winds aren’t as strong as they are forecasting.”

That is the essence of get-home-itis, and there is not a one of us immune to it. Pilots can, however, allow common sense to sit on the other shoulder and balance such musings. For every “maybe the forecast is off,” one has to imagine “yeah, it could be turn out worse than what they are saying.” After all, a forecast is only a guess of how the weather gods will play out the day. A sophisticated guess based on lots of data, but a guess, nevertheless.

For every “I have got to get home and be at work tomorrow,” there has to be, “this is what personal days and telecommuting are made for.” Building a weather day or two into holiday vacations can alleviate all of these ruminations. I do it as a matter of course. The plus is that if I get home the day I expected to get home I have a day to decompress before ordinary life reaches out and grabs me again. And if I need the extra day because home or en route weather is bad? Well, I’ve got it.

Another good hedge is a back up plan, such as refundable airline tickets (yep, pricey, but only if you need to use them), or a car rental that you can cancel last minute. I’ve used them both to get where I needed to be when the weather prevented me from flying myself.

And what about the “look-see” approach to flying on marginal or worse weather days? 14 CFR Part 91 leaves pilots a lot of leeway on planning flights when the weather might not be at minimums upon reaching the destination. I’m pragmatic on this one. If you are a current pilot in a well-equipped aircraft who has lots of experience with the type of weather you’d like to “look-see” well, run it through your common sense rubric. If it passes, plan the flight with several “outs,” places you’ll divert to if needed. The go ahead and give the flight a try. Weather is a dynamic beast, and conditions may be better than forecast, or worse. You’ll know when you are up there, hopefully deviating around it or diverting to avoid it. Good luck.

Ultimately the key to short circuiting the day-after get-home-itis syndrome in aviation is proper planning, preparation, and of course, a realistic understanding of your aircraft and your own capabilities. Pilots, know thyself. Fly safe out there!

Encouraging People to Replace Us

November 25th, 2015 by Rob Mark

Finding young people to grab the reins from us old guys in aviation is a bit like the weather … everyone talks about why we need to do something, but not everyone is clear about how to actually make that happen. Certainly doing nothing is the wrong answer. So what can we do to increase our odds of connecting all the right people together?

NBAA 2015 yoproAt the recent NBAA convention, the association offered a number of us an opportunity to mingle with a hundred or so officially named Young Professionals who’d volunteered to listen to us more-experienced (secret code for older) industry folks detail how we started while also delivering a bit of unsolicited advice for job seekers.

The NBAA team was spearheaded by the association’s Sierra Grimes with Brett Ryden from Southcomm’s Aviation leading a group of his editors who together created an hour’s worth of practical education at the show’s Innovation Zone. The panel was evenly split between ladies and gents … myself, Jo Damato from NBAA, Sarah Barnes from Paragon Aviation and Textron Aviation’s senior VP of Customer Service Brad Thress. Our moderator was writer Lowen Baumgarten.

Stage members spent a few minutes detailing their experiences, but since we were there to answer questions, I was antsy to interact with the audience. Over the course of the hour there were perhaps seven or eight good ones, but I wanted more. I probably shouldn’t have.

Reality kicked in for me about 20 minutes after we began as I realized that some of what a number of young people had told me the night before was really true … networking is not an innate skill, not even close. I’d seen this kind of thing before too. Universities apparently assume graduates automatically absorb networking skills out of thin air I guess. Read the rest of this entry »

Why I fly high

November 23rd, 2015 by Mike Busch

I take a lot of long trips in my Cessna T310R, and more than half of them involve cruising up in the high teens and low Flight Levels, simply because those are the altitudes at which my airplane is happiest, fastest, and most efficient. But from what I’ve been able to tell, the great majority of piston pilots shy away from using the high-altitude capabilities of their airplanes. Most pilots of normally aspirated airplanes seem to confine most of their flying to altitudes of 10,000’ and below, and even many pilots of unpressurized turbocharged airplanes like mine have never flown in the Flight Levels. It’s even surprising how many pilots of pressurized birds seem averse to flying much above the low teens.

That’s a shame, because it’s at the high end of the altitude spectrum that most of our airplanes achieve their best efficiency—and in many cases, their best speed as well. I’m not just talking about turbocharged airplanes. Most normally-aspirated birds are perfectly capable of cruise altitudes well into the teens.

Look at a plain-vanilla, fixed-gear, normally-aspirated Cessna Skylane:

Cessna 182Q Range Profile

Cessna 182Q Skylane range profile page from POH.

At a low altitude like 4,000’, maximum cruise speed is 139 KTAS at 75% power. Continue climbing until the airplane “runs out of throttle” at 8,000’ and max cruise climbs to 144 KTAS. That extra 5 knots will save you 9 minutes on an 800 NM trip when you take the extra climb into account. (5:38 instead of 5:47, no big deal).

Continue climbing to 12,000’ and max cruise drops back to 139 KTAS (same as at 4,000’), but at a much more fuel-efficient 64% power (which is all you can get at that altitude with wide-open throttle). The same 800 NM trip will take 6 more minutes at 12,000’ than at 4,000’ (5:53 to be exact) because of the longer climb, but burn a whopping 12 gallons less fuel in the process—if avgas costs $5/gallon, that’s $60—and increase IFR range by a full hour and 130 NM!

How far can we take this? Don a cannula and climb to 16,000’—high enough to fly right over the Front Range of the Rocky Mountains IFR—and max cruise drops to a still-respectable 130 KTAS at a miserly 53% power. Because it takes a Skylane nearly 40 minutes to climb from sea level to 16,000’ at max gross, the 800 NM trip will take a half-hour longer than at 12,000’ (6:23), but will save 20 gallons ($100?) and increase IFR range by a full two hours compared to our 4,000’ benchmark.


To fly an
800 NM Trip

4,000 139 K 820 NM 5:47 78 gal
8,000 144 K 840 NM 5:38 79 gal
12,000 139 K 950 NM 5:53 67 gal
16,000 130 K 1,040 NM 6:23 59 gal

Normally-aspirated, fixed-gear 182Q
(maximum gross weight, standard day, no wind,
88 gallons, 45 min reserve)

Unless you just happen to like low-and-slow, there’s no logical reason to cruise a Skylane lower than 8,000’ because doing so makes all the numbers worse: cruise speed, trip time, and range.  On the other hand, climbing to 10,000’ or 12,000’ will cost you a negligible amount of time, and reward you with substantially lower fuel burn and increased range.

These calculations are all based on zero-wind, but in real life the winds aloft are often a decisive factor in determining the best altitude to choose. If you’re headed eastbound, odds are you’ll have a tailwind—and the higher you fly, the better it’ll be.

In wintertime, climbing up high to catch favorable winds can pay off spectacularly. In the low-to-mid teens, 50 knot tailwinds are commonplace and a 70 or 80 knot tailwind is possible. Even in summer, when winds tend to be relatively light, going high can pay off. Here are some typical summer winds I pulled off of DUATS:

      6000    9000   12000   18000
 STL 2410+18 2809+12 3110+07 2917-04
 SPI 2510+18 3010+12 3211+07 2919-05
 JOT 2511+17 3012+12 3116+06 2926-07

 CVG 2210+15 2809+11 3012+07 3021-05
 CMH 2210+14 2710+10 2914+06 3026-07
 CRW 2108+15 2509+10 2908+06 3225-05
 AGC 2010+12 2510+09 2813+05 2930-09

 EMI 9900+11 2905+09 2811+05 2927-10

Even in these docile summertime conditions, we can expect 10 to 15 knots more tailwind component at 16,000’ than at 8,000’, which almost exactly offsets the TAS advantage of the lower altitude (144K vs. 130K). By climbing up high on an eastbound trip, we’ll go just as fast, burn considerably less fuel, and increase our IFR range nearly 400 NM! Not to mention that it’s almost always smoother and cooler up high. What’s not to like?

During the winter, when the winds tend to be stronger, going high on eastbound trips tends to be an even better deal, saving both time and fuel.

For turbos, it’s even better

If you’ve got a turbocharger, the argument for flying high becomes compelling, because the higher you fly in a turbo, the higher your speed, range and efficiency—at least up to the low Flight Levels in most turbocharged airplanes. These birds really shine up in the high teens and low twenties, and pilots who don’t take advantage of this capability don’t know what they’re missing.

For example, take a look at the “Range Profile” page for my Cessna T310R:

Cessna T310R Range Profile

Cessna T310R range profile page from POH.

Starting at 180 KTAS at sea level, max cruise speed at 73.6% power steadily increases with altitude to a relatively blistering 221 KTAS at FL200. (Above that altitude, available power starts dropping off fairly rapidly.)

Cruise Altitude Max
To fly an
800 NM Trip
5,000 190 K 860 NM 4:14 143 gal
10,000 199 K 890 NM 4:04 137 gal
15,000 209 K 930 NM 3:55 131 gal
20,000 221 K 970 NM 3:45 125 gal

Turbocharged, twin-engine Cessna T310R
(73.6% cruise, maximum gross weight  standard day, no wind,
163 gallons, 45 min reserve)

At the same time, range with IFR reserves climbs from 820 NM to 970 NM. Naturally, trip time and fuel burn for the proverbial 800 NM trip both drop accordingly—from 4:14 and 143 gallons at 5,000 to 3:45 and 125 gallons at FL200.

Personally, I don’t push my engines this hard. I almost always throttle back to between 60% and 65% power and settle for around 205 KTAS at FL200 at a miserly fuel burn of 26 gallons/hour, giving me a range of well over 1,000 NM with IFR reserves (or 1,200 NM if I fill my 20-gallon wing locker tank).

Once again, these figures assume no-wind conditions. Add in the wind on an eastbound trip and the results can get downright exciting. In the winter, I’ve seen my groundspeed edge above 300 knots from time to time. That’s fun! During the summer, on the other hand, I’m happy with 230 or 240 on the GPS readout.

Needless to say, you pay the piper going westbound. But if the winds aren’t too strong, it may still pay to go high rather than low. In my airplane, I gain 22 knots of true airspeed by climbing from 10,000’ to FL200. So if the headwind at FL200 is only 10 or 15 knots stronger than at 10,000’ (which is usually the case in summertime), higher is still better.

In wintertime, of course, westbound aircraft are all in the same boat, turbo or non-turbo. We bounce along at the MEA, try not to look at the groundspeed readout, hope the fillings in our teeth don’t fall out, and think about how much fun the eastbound part of the trip was (or will be).

Enjoy the high life!

If you’re one of those pilots who comes from the “I won’t climb higher than I’m willing to fall” school, you’ve got nothing to be embarrassed about. Believe me you’ve got plenty of company. But you’re also missing something really good.

Do yourself a favor: give high a try. It’s cooler and smoother up there. Your airplane flies faster and more efficiently up high. ATC will usually give you direct to just about anywhere. You’re above terrain, obstructions, and often the weather and the ice. The visibility is usually terrific. So are the tailwinds, if you’re lucky enough to be going in the right direction. Try it…you just might like it!

See & Avoid Doesn’t Work

November 10th, 2015 by Ron Rapp

Contemplate the worst scenario that might confront a pilot during a flight. What comes to mind? Fire? Flight control failure? Engine failure? Perhaps it’s flight crew incapacitation, explosive decompression or severe structural damage.

No doubt about it, those all fall into the Very Bad Day category. But there’s one that can be even worse: a mid-air collision. That’s because it can involve all the problems listed above — at the same time. And since the parties involved aren’t aware of the impending crunch until it’s too late, the mid-air is usually accompanied by a violent element of surprise, confusion, and initial denial.

You might think fatal mid-airs are rare events, and from a purely statistical standpoint I’d have to agree. According to the 2010 Nall Report, a fatal mid-air occurs about once every 8 million flight hours. Think of it as the roughly the same odds as winning the lottery or being struck by lighting. Doesn’t sound so bad, does it? A typical GA pilot might accumulate but thousand or so hours over a full lifetime of flying.

So what’s there to worry about? Plenty. The “big sky” theory may sound good, but it doesn’t hold up very well under close scrutiny. It’s true that the navigable atmosphere over the United States alone is massive — about 20 million cubic miles — and there are relatively few airplanes in the sky. Even on those occasions where a collision is possible, modern tools such as radar, TCAS, VHF communication, and anywhere between two and four sets of eyeballs almost always succeed in averting the disaster. If aircraft were equally distributed throughout the atmosphere, the “big sky” idea would be pretty comforting.

But airplanes cluster near airports, large cities, and on thin slices of the sky known as “airways”. For the VFR types, airspace and terrain often crowd planes into small swaths of the air in places like the Santa Ana Canyon or Banning Pass. The sky is much like the ground: vehicles stick to relatively confined spaces and that makes collisions a serious hazard.

Since we’re on the topic of statistics, let me give you a few of my own: I personally know two people who have been struck by lightning, and a winning lottery ticket was recently sold not 300 feet from my front door. Hey, crazy stuff happens. But unlike lighting strikes and golden tickets, we’re not all facing the same odds. The risk profile varies widely depending on the type of flying you’re doing.

For example, flight instruction is frequently a factor; thirty-seven percent of mid-airs occur with a CFI on board. Many instructional flights happen near airports, and as previously mentioned, that’s where other airplanes tend to congregate. On the other hand, if you fly airliners, your risk of a mid-air is rather low because the aircraft itself is large and easy to see, you’re always flying IFR, and the most sophisticated traffic avoidance hardware available is always installed. Airliners also spend most of their time in cruise and are in constant radar contact with ATC.

Midair collisions are almost as old as powered flight itself.  This B-17 collided with a German fighter over Tunisia in 1943.

Midair collisions are almost as old as powered flight itself. This B-17 collided with a German fighter over Tunisia in 1943.

Think it can’t happen to you? Think again. Some very talented, capable, and well-respected pilots have been involved in mid-air collisions. I know a guy who was involved in one while flying a large-cabin, TCAS-equipped business jet under Instrument Flight Rules. Alan Klapmeier, the founder of Cirrus Aircraft, was in one too. Richard Collins, famed Flying columnist, was in a mid-air. Speaking of Flying, the recent Editor-in-Chief owns a very nice Cirrus SR-22 which was in a mid-air. And lastly, a decade ago I was in a mid-air collision myself.

I’ll save the blow-by-blow (no pun intended) on that for another day. The point I’m trying to make is that the odds of a mid-air are probably greater than you think, especially if you live in a populated metropolitan area and fly VFR. If you’ve ever had a close encounter with another airplane in flight, you were only separated from “those who have” by nothing more than a miniscule sliver of plain old luck.

Think about that for a moment.

This may be hard to believe, but there is some good news. For one thing, mid-airs are not always fatal. It seems intuitive that most collisions would involve fatalities, but all the people I cited above survived, including (obviously) myself. Also, technology is rapidly advancing, from cheap TCAD boxes to airframe parachutes to super-bright LED exterior lighting.

The question we should all be asking ourselves is how we avoid ending up in a mid-air, fatal or otherwise. If you refer to official guidance from the FAA, the answer is to simply look out the window and spot the other airplane before it hits you. This technique, referred to as “see and avoid”, is still considered adequate for preventing collisions. Here are a couple of passages from Chapter 1 of the Airplane Flying Handbook:

The “See and Avoid” concept relies on knowledge of the limitations of the human eye, and the use of proper visual scanning techniques to help compensate for these limitations. The importance of, and the proper techniques for, visual scanning should be taught to a student pilot at the very beginning of flight training.

Proper clearing procedures, combined with proper visual scanning techniques, are the most
effective strategy for collision avoidance.

Other FAA publications, ranging from the Aeronautical Information Manual, to Advisory Circulars like AC-90-48 (“Pilot’s Role in Collision Avoidance”) will give you the same spiel: “see and avoid will keep you safe”. And it will! Until it doesn’t.

From my perspective as someone who’s been in a mid-air and who was using proper clearing and scanning techniques at the time, I take it as gospel that “see & avoid” won’t always do the trick. I’m just one guy, of course. But many others — some institutional in nature — just happen to agree with me.

For example, a couple of years ago Canada’s Transportation Safety Board issued an accident report on a mid-air collision between a Beech V-35B Bonanza and a PA-28 Cherokee over northern Virginia. Canada was tasked with performing the investigation because the pilots of the Bonanza were employees of the NTSB while the Cherokee was piloted by an employee of the FAA.

I won’t keep you in suspense. The conclusion from the TSB was that the “see and avoid” concept was inadequate. They even quoted a 1991 report produced by the Australian Transport Safety Bureau which provides an overview of the major factors that limit the effectiveness of the see-and-avoid principle in preventing mid-air collisions, as well as a 2005 scientific study published in Aviation, Space, and Environmental Medicine which came to the same conclusions.

The main points:

  • Cockpit workload and other factors reduce the time that pilots spend in traffic scans, and even when pilots are looking out, there is no guarantee that other aircraft will be sighted.
  • Visual scanning involves moving the eyes in order to bring successive areas of the visual field onto the small area of sharp vision in the center of the eye. The process is frequently unsystematic and may leave large areas of the field of view unsearched.
  • A thorough, systematic search is not a solution as in most cases it would take an impractical amount of time.
  • The physical limitations of the human eye are such that even the most careful search does not guarantee that traffic will be sighted.
  • The pilot’s functional visual field contracts under conditions of stress or increased workload. The resulting ‘tunnel vision’ reduces the chance that an approaching aircraft will be seen in peripheral vision.
  • The human visual system is better at detecting moving targets than stationary targets, yet in most cases, an aircraft on a collision course appears as a stationary target in the pilot’s visual field.
  • An approaching aircraft, in many cases, presents a very small visual angle until a short time before impact.
  • Complex backgrounds such as ground features or clouds hamper the identification of aircraft via a visual effect known as ‘contour interaction’. This occurs when background contours interact with the form of the aircraft, producing a less distinct image.
  • Even when an approaching aircraft has been sighted, there is no guarantee that evasive action will be successful.
  • Because of its many limitations, the see-and-avoid concept should not be expected to fulfill a significant role in future air traffic systems.
  • Transportation Safety Board of Canada aviation investigation report A06O0206 identified that there is a high risk of mid-air collisions in congested airspace when aircraft are not alerted to the presence of other aircraft and rely solely on the see‑and-avoid principle.

There’s one more area of the TSB report which is worth of quotation. In it, they reference a British Royal Air Force study into mid-air collisions. If you’re keeping score, that’s the third sovereign agency to reach the conclusion that “see and avoid” is inadequate. Yet our own FAA, which oversees about 80% of the world’s aircraft and almost all of the high traffic density airspace, still officially proclaims that one can look out the window and see everything that needs to be seen.

This accident has demonstrated yet again that relying solely on the see-and-avoid principle to avoid collisions between aircraft operating under visual flight rules (VFR) in congested airspace is inadequate.

A number of international studies have addressed the overall issue of the effectiveness of the see-and-avoid principle, as well as the risks of collision associated with this principle. All acknowledged the underlying physiological limitations at play and that, when mid-air collisions occur, “failure to see-and-avoid is due almost entirely to the failure to see.”

One study stated that “our data suggest that the relatively low (though unacceptable) rate of mid-air collisions in general aviation aircraft not equipped with TCAS [traffic alert and collision avoidance system] is as much a function of the ‘big sky’ as it is of effective visual scanning.”

A British Royal Air Force study into mid-air collisions, which were deemed to be random, found that the probability of conflict is proportional to the square of the traffic density, and recommended avoiding altitude restrictions that concentrate traffic.

Measures such as improving aircraft conspicuity, pilot scanning techniques, and pilot traffic awareness can reduce risks, but they do not overcome the underlying physiological limitations that create the residual risk associated with a see-and-avoid method.

It’s obvious that “see and avoid” cannot, by itself, ensure our safety. If it could, there’d be no need for TCAS or most of our controlled airspace (both of which came about because of high-profile mid-air collisions, I might add!). I’m not necessarily in favor of mandating any additional equipment, airspace, or restrictions, especially on general aviation. But it’s clear that serious changes are needed in how collision avoidance is taught, especially as it concerns “see and avoid”. The concept has serious limitations which must be understood so the pilot-in-command can make educated decisions about how — or even if — they want to mitigate those risks.

I sincerely hope our nation’s regulatory and safety organizations will eventually acknowledge what we all know to be true: “see and avoid”, while a good start and certainly a vital part of collision avoidance, is simply not sufficient to ensure traffic separation.

Use it, or lose it: protecting our smaller airports through increased activity and community involvement.

November 9th, 2015 by Jolie Lucas


Aircraft Crashes into Buildings


Sometimes this headline is the only press we receive at General Aviation airports. While this is comical and lighthearted, the lack of education about the value of our airports in the non-flying public, as well as perhaps a bit of apathy on the part of the flying public, can be very dangerous indeed. As you will see below, our GA airports are a goodwill generator, and an economic engine for a community.

This past Saturday was a perfect day at Oceano Airport [L52]. The temperature at the coastal airport was 75 degrees with a light breeze. With our December 5th Toys for Tots event coming up, it was a day for decorating. I suppose I was at the airport for about two hours. What struck me was the amount of activity at this small G.A. airport.

  • SkyDive Pismo Beach was busy dropping divers who must have had an awesome view of the Pacific Ocean. The jump plane was at the pumps of Oceano Fuel at least three times.
  • Banner Airways was giving aerobatic flights in the 1943 Super Stearman. They had just filmed a wing-walking segment for the local newscast.
  • I spoke with visitors who flew in from Palo Alto because they had always wanted to camp here.
  • Another couple from Long Beach borrowed the Fly N Ride bikes we have available for loan to ride to the Monarch Grove and the Pismo Pier.
  • Two Pilots N Paws planes came in, coordinating the transfer of several doggies to their forever homes.
  • I also spoke with a family with younger children. They were thrilled that the beach was within walking distance, as was a county park with play area.
  • A student and instructor from Pacific Aerocademy were working the circuit.
  • And Friends of Oceano Airport volunteers were fixing tubes on our loaner bikes and getting ready for Toys for Tots.

Do I think that there is something special about Oceano Airport? Or was this a typical day at most any GA airport? Well, I do believe that our area on the Central Coast of California is very special. To have a 75-degree day in early November, well it makes the high price at the gas station almost worth it. However, I think that our smaller GA airports all have something special to offer our visitors and communities.

In 2010 I formed the Friends of Oceano Airport to mobilize the pilot population and community to protect our airport from a developer who decided he had a better idea of how to use the land Oceano sits on. Over the objections of county officials, he pressed ahead with highly controlled “public” meetings to try to win community support to close the airport and let him build on it. Fortunately we were able to revitalize the airport through some general upkeep, but more importantly entice visitors and our local community to come to the airport by having fun events.

I made the following graphic for a presentation series a few years back. Hopefully we can all keep in mind that we need to be protective of our community airports.

Say again?

November 3rd, 2015 by Amy Laboda

Cockpit noise is far more than just a nuisance. 

I live and work at a small airport. That makes me an expert on noise. I’ve heard it all, from the thop-thop of helicopter blades beating against thick morning air to the supersonic roar of propeller blades on a Cessna pulling it skyward; from the hum of GE turbofans on takeoff to the gentle chirps of rubber on asphalt, followed by a deep roar as the pilot hits the thrust reversers.

And that’s just what I hear standing outside my office. External airport noise, real as it is, generally pales in comparison to the hearing-damaging decibels most of us encounter when our ears are unprotected in the cockpit of a small piston- or turbine-powered propeller airplane or helicopter. I’ve been subjecting myself to these kinds of noises, both on the ramp and in the air for neigh on 45 years, first as a passenger, then as a professional pilot and I can tell you, hearing loss in our profession is real. And the fatigue that comes from being subjected to such loud and constant sound all day or night long is real, too.

Let me quantify this for you. How loud is too loud? Permanent hearing damage can occur from sounds louder than 85 dB, and physical pain occurs at around 125 dB. You decibel_exposure_chartcan burst an eardrum at 140 dB—a level reached by a jet engine revving up on the ramp as its pilot throttles up to taxi out for takeoff. The graphic at right shows how much a human ear can stand before damage. OSHA requires workers exposed to noise levels higher than 85 dB to use hearing protection equipment.

OSHA is not being overprotective. I fly one of the noiser airplanes out there, an RV-10 with a two-blade propeller. Two-blade propellers are longer than three blade varieties, and have been documented as making more noise. I’ve also got fixed gear, and no sound insulation (we never even got around to putting in a headliner). Measured decibels on takeoff from inside the cabin are—yeah I’m not going to tell you. It’s bad.

Our solution to the noise problem is pretty modern and probably as lightweight as you can get: we opted for high quality active noise canceling headsets. To cancel the lower-frequency portions of the in-flight noise, noise-cancelling headphones incorporate a microphone that measures ambient sound, then generate a waveform that is the exact negative of the ambient sound, and finally, they mix it with any audio signal. Most noise-cancelling headsets in the consumer market generate the noise-cancelling waveform with analogue technology.

Digital processing is the next frontier, and the realm of the high-end headsets. The most sophisticated ANR headsets use digital sound mapping to customize their noise cancellation. Bose A20, Lightspeed Zulu PFX, Sennheiser S1, AKG—these headsets demand a premium, but put them on and fly with them in a noisy cockpit such as mine, and you’ll understand why.

aloftTo prevent higher-frequency noise from reaching the ear, most noise-cancelling headphones depend on soundproofing and an excellent fit around the ear. Higher-frequency sound has a shorter wavelength, and is tougher to cancel out. In-the-ear headsets such as Clarity Aloft can claim to efficiently dull the higher-frequency sounds of wind over the fuselage (its louder than you’d think), and generally can do so without the need for active noise cancellation. On long trips it is nice not to have an over-the-ear headset squeezing the stuffing out of my brain. That said, a lot of people don’t like the feel of earplug-type headsets in the ear canal. And if the fit isn’t perfect the noise seeps in. For a price some of these headsets can be fitted with custom shaped ear plugs, but that requires an audiologist to fit them, and a lab to make them.

There are some people who insist that headsets are not the only answer. They spend a lot of time and money insulating their light aircraft cockpits from sound. Today’s lighter weight materials can, if properly applied beneath the floor panels, side panels, bulkheads and headliner, soften external low and high frequency sounds to bring the level at cruise down below 80 dB, but not much lower.

I’m not a fan of the extra weight and complexity that such sound deadening material can add to an aircraft (complexity comes in if you have a certified aircraft: think field approvals and STCs here). I’d rather spend that money on lightweight, high-end digital ANR headsets to connect everyone in my cockpit. I put that money into a decent audio selector panel and intercom, with the ability to isolate the pilot from the conversation in the cabin, when necessary. While I’m isolated and able to communicate clearly with ATC, my companions can talk amongst themselves or even listen to music during the flight. Everyone is happy, and their hearing stays intact.

When Good Enough Just Isn’t

October 21st, 2015 by Rob Mark

Tony Kern, CEO of Convergent Performance

I spent much of last week in Wichita, the nation’s air capitol, to attend an annual safety trek known as the Safety Standdown, jointly hosted by Bombardier and the National Business Aviation Association (NBAA).

This 19th edition of the event drew about 450 attendees and another 1,100 online to listen to a host of smart, savvy aviators speak passionately about the need to head off accidents before they happen.

Before we prang an airplane applies to all of us and certainly doesn’t sound like rocket science anyway, does it? Read through the latest NTSB statistics and you’ll realize this simple philosophy apparently was rocket science to the pilots of the 566 GA accidents in the first eight months of 2014. The question of course is why?

Now if I start talking about professionalism in the midst of these accidents statistics most readers will think I’m referring to big-iron pilots paid to fly.

On the surface, professionalism’s a tag that on the surface doesn’t seem to fit with an Archer or a Cirrus driver, but it should, because thinking professionally, according to Dr. Tony Kern of Convergent Performance, can shape how we fly. At the Safety Standdown, Kern was an engaging, take no prisoners, kind of speaker and his logic is tough to refute once you’ve listened and let the philosophy sink in (watch his opening session talk).

Consider the Practical Test Standards, a booklet anyone who’s earned a pilot certificate knows well. It’s all about the limits the flight test examiner expects us to work with … how many feet + or – an applicant can stray in altitude, heading and airspeed for example. Meet the minimum standards for the pilot certificate and you’re probably home free. Airline and biz jet pilots fly to their certificate standards during their annual recurrent training too. They’re just checked once or twice a year. Read the rest of this entry »

Assault on GA Down Under

October 9th, 2015 by Mike Busch
Nick McGlone

Nick McGlone with one of his Cessna 210s.

I just got off the phone with my good mate Nick McGlone from Sydney, Australia. For decades, Nick has operated Nautilus Air Services at Sydney’s Bankstown Airport. His firm operates a fleet of Cessna 210 Centurions whose primary mission is to haul sushi-grade fresh fish every day from Tasmania to Sydney. It’s roughly 650 miles from Sydney to Tasmania as the crow flies, about one-third of it overwater.

Now 70, Nick might just be the highest time Cessna 210 pilot in the world, with well over 30,000 hours in type. He’s also a master mechanic (they call them “LAMEs” down there) who maintains his airplanes in tip-top shape. He has to because he depends on them to be mission-ready every day.

After we exchanged a few pleasantries, Nick told me that his airplanes hadn’t flown for months and he was not confident that they would ever fly again. That stopped me dead in my tracks; he had my attention.

CASA’s War on Aging Aircraft

Nick explained to me that in recent years, Australia’s Civil Aircraft Safety Authority (CASA)—the Aussie counterpart to our FAA—had been implementing a series of draconian policies calculated to make it economically impossible for owners of legacy GA aircraft to keep them flying. He said that Bankstown Airport—traditionally the busiest GA airport in Australia—had become a virtual ghost town.

It seems that in 2014, the powers-that-be at CASA handed down a startling ruling that all operators of Australian-registered Cessnas would be required to comply with Cessna’s Supplemental Inspection Documents (SIDs). These SIDs set forth an extraordinarily extensive program of structural inspections that Cessna wants performed on a regular basis.

Some of the inspections in Cessna's SIDs are invasive, labor-intensive, and expensive.

Some of the inspections in Cessna’s SIDs are invasive, labor-intensive, and expensive.

Some of these inspections are relatively easy, but some are extraordinarily invasive and labor-intensive and costly. The SIDs specify a complex matrix of initial and repetitive compliance times for these various inspections. The most invasive and labor-intensive ones are to be done initially when the aircraft reaches 20 years old, and then repetitively every 3, 5, or 10 years thereafter. Of course, since all Cessna 300/400-series piston twins and all 200-series singles and the vast majority of 100-series singles are 30-60 years old, all of them are now past due for these inspections.

The FAA has ruled that compliance with these SIDs is strictly voluntary—NOT compulsory—for U.S.-registered aircraft that are maintained in accordance with the U.S. FARs. But CASA’s 2014 ruling was the exact opposite, and mandates that all Australian-registered aircraft MUST comply with the SIDs, whether the aircraft are in commercial service or private use.

Nick said that this is a catastrophe for Cessna owners in Australia (and in other nations like New Zealand and Germany and Spain who have also ruled that the SIDs are compulsory). Although the FAQ on CASA’s website says that compliance with the SIDs should cost about $20,000, Nick indicated that owners are finding that the actual cost of compliance is between $80,000 and $120,000 for Cessna singles, and close to $200,000 for Cessna twins. This is more than many of these aircraft are worth—or WERE worth before CASA made its ruling. Now, says Nick, the market value of these aircraft in Australia has dropped to near-zero, and many Australian owners are being forced to crate up their aircraft and ship them for sale in the U.S. (where compliance with the SIDs is not required).

Not Just Cessnas, Not Just SIDs

This catastrophe isn’t just limited to Cessnas, either. Now that Cessna’s parent company Textron Aviation owns Beechcraft, they’re feverishly working on developing a SID program for Bonanzas and Barons and other aging Beech airplanes. CASA has made it clear that the moment these Beech SIDs are published, CASA will mandate their compliance. There is even a rumor that Piper is working on a SID program for aging Piper airplanes.

All stainless steel control cables on Australian aircraft have to be replaced by the end of 2017.

All stainless steel control cables on Australian aircraft have to be replaced by the end of 2017.

And if that wasn’t bad enough, CASA has a few other tricks up its sleeve to make operation of aging GA aircraft unaffordable in the land down under. There’s a new Australian AD issued last February that requires that all primary flight control cables that use stainless steel end fittings (as almost all do) must be replaced with new cable assemblies by the end of 2017.  And another Australian AD that requires that all propellers undergo a complete disassembly inspection every six years and a major overhaul at the prop manufacturer’s specified TBO. None of these things are mandated by the FAA for U.S.-registered airplanes, nor is there a history of accidents or incidents in either country to justify such costly maintenance burdens on the owners of GA aircraft.

Nick told me that he is convinced that Textron and perhaps other manufacturers simply want their older aircraft to go away, and that they’ve been successful in enlisting CASA and various other national CAAs in helping them to achieve that goal. All of this is shrouded in the mantle of “aviation safety” despite the fact that there’s virtually zero history of accidents being caused by structural failure, control cable failure, or failure of high-time propellers. Nick could be right.

So next time you start griping about the high cost of personal flying, you might pause and thank your lucky stars that you’re based in the U.S. and not in the land down under. Compared to the rest of the world, we American aviators have it mighty good.

Perseverance pays off for local high school teacher and students.

Steve Smith is a teacher at Canyon High School in Anaheim, California who started an aviation program. This multi-year curriculum takes students from an overview of aviation to potentially passing the written and getting college credits. Talking with Steve about his original idea he says, “My first few years on campus I noticed we had classes such as auto shop, culinary arts, computer science, film and I started to think how cool it would be to have a pilot ground school option.  I sat on the idea for a year or two and then started asking questions.”

Perseverance paid off for Steve after three years of trying. “ I talked with many people at my school, at my district, and even the county.  Everyone I spoke with was very positive and receptive but they couldn’t tell me how to actually make it happen.  Finally, the district hired a new CTE coordinator and she loved the idea and put the pieces in place to get the program approved and created” says Smith.Classroom

I asked him where his love of aviation came from. “You know, I did not have a lot of exposure to GA growing up.  I never even considered being a pilot until I stumbled into the Aviation Sciences department at Baylor University as a sophomore.  They told me that flight training was a required component of the degree program and I remember saying, “you mean, you will let me fly an airplane?”  I think that plays in to the importance of a program like ours.  There are many jobs on the horizon in the aviation industry, and it is important for students to get some exposure now and start investigating the possibilities.”


The Plan:

Year 1 – This class is mostly for freshman focusing on career opportunities in Aviation and Aerospace. Students will see the vastness of the industry and to start narrowing in on what they are passionate about when it comes to potential future employment.

Year 2 –Aviation I exposes students to aviation professionals, concepts, and opportunities while covering the first portion of the Private Pilot ground school content knowledge. Advanced Simulators are used to teach flying skills as part of the curriculum during class.

Year 3 – Aviation II picks up where Aviation I leaves off. Students receive the rest of their Private Pilot knowledge content and can be signed off at the end of the year to take the FAA written exam. Completion of Aviation I and II may allow students to receive college credit should they choose to enter most collegiate aviation programs. Students will continue to train on the simulators as well.

Year 4 – Internship programs with local aviation partners to allow students to receive high school credit while off campus working directly with aviation professionals in ANYTHING such as aircraft maintenance, air traffic control, business, airport operations, engineering, design, or maybe even flying!

The funding:

The school secured a STEM planning grant of $50,000 from the district, which was paid for classroom furniture and two flight simulators. A $100,000 implementation grant from the district this year paid for four new simulators in addition to class sets of Chromebooks and flight planners.

This wonderful program is now operational because an aviation lover, and creative thinker had passion and perseverance. Imagine if we all took one good idea and tried, and tried, and tried.

What a country!

October 6th, 2015 by Ron Rapp

“No one realizes how beautiful it is to travel until he comes home and rests his head on his old, familiar pillow.” –Lin Yutang

Even before I started flying for a living, traveling internationally always made me appreciate what we have here at home. Most people are aware of the hassles involved with long-distance international journeys: you’ve gotta consider passports, visas, different electrical outlets and voltages, language barriers, currency exchange, jet lag, and more. Perhaps that’s one of the reasons traveling the world can be so rewarding: much like flying, it’s not easy. You’ve got to earn it.

When you’re the one doing the flying, things are even more complicated. If you’ve followed the travails of any of the Earthrounders – people who fly light GA aircraft around the world, often to raise money or set some kind of record – you’ll notice they all have one thing in common: an inordinate number of delays, problems, and hassles in transiting from one country to another. Given the fact that those of us who do it for a living are not only more experienced with international operations, but also have professional dispatchers, handlers, and staff behind us, you’d think we’d eventually surmount these obstacles.

You’d be wrong.

My trusty steed is fueled and ready for  departure on another intercontinental trip.

My trusty steed is fueled and ready for departure on another intercontinental trip.

I recently participated in a series of trips which took our airplane to China and back – twice – and then eastbound across the world to explore Africa before coming home. It once again reminded me of what incredible barriers humans can erect to keep would-be travelers tied up in bureaucratic knots.

Here are just a few examples:

Visas. Sometimes we need them, sometimes not. Other times crew members have their own specific visa requirements. If you get it wrong, you’ll find yourself missing that flight you were supposed to be on. It’s an especially big problem if you were the one who was supposed to be piloting the plane! There are some countries where even with the right paperwork, you’ll be denied entry if they see you’ve been to a country with which they’re on unfriendly terms.

Customs. It’s bad everywhere, but this might be one place where returning to the U.S. is the worst. I once had a passenger manifest consisting of a half-dozen U.S. Customs agents. I figured we’d breeze through the clearance process upon returning to the United States – after all, these guys had diplomatic passports and active Immigration & Customs Enforcement credentials. The reality? We had to shut down the aircraft, offload all luggage, and traipse across a large airport to clear Customs. One of our passengers was detained briefly because he had a “common name”. I was baffled. If Customs doesn’t trust Customs agents from their own department, there’s something wrong.

Handlers. When flying internationally, we hire professionals who specialize in dealing with the local procedures, folks who know the ropes and speak the language. They arrange our fueling, interface with ramp personnel, airport employees, drivers, and so on. They handle the paperwork and speed us on our way. Or not. Some handlers do a great job, others are awful. On one trip I handed off the aircraft to a subsequent crew who were literally held up – detained — for a cash “fee” by the handler who was supposed to be keeping just that sort of thing from happening. It’s like being robbed at gunpoint by your own bank.

Flight planning. In the United States, we take many things for granted. Altitudes are given in feet. Speeds are expressed in knots or miles per hour. Fuel is dispensed in gallons. Once you venture abroad, you’ll find countries which utilize things like meters, hectopascals, and liters. I haven’t seen cubits or fathoms used yet, but it wouldn’t surprise me. There are places where altitudes are sometimes in meters, other times in feet. In certain countries, usually those with plenty of mountainous terrain, altitudes are referenced to the airport elevation rather than sea level. It’s easy to confuse terms like QNH, QFE, and QNE. Get it wrong in those places and you can find yourself flying into the side of a mountain!

This will soon replace the domestic IFR flight plan form as the U.S. conforms to ICAO standards.

This will soon replace the domestic IFR flight plan form as the U.S. conforms to ICAO standards.

Paperwork. In the U.S., we can get weather information from a wide variety of sources, from telephone briefings to iPhone apps. Abroad, you’ll find yourself forced to purchase, if not use, their weather products. You’ll be required to obtain various stamps and approvals. This can involve long waits and unexpected delays. Indians seem to love their paperwork more than just about anyone I’ve seen. Overflight or landing permits can take days, sometimes weeks to obtain. In countries like China or Russia, there are no short-notice trips for private or business aircraft because they’re impossible. Change your plans? Running late? You’re just out of luck.
Even in Europe, flights can require slot reservations, much the way special events like the Super Bowl do here in the U.S. If you miss your slot time, you go to the bottom of the list. Have you ever seen an ICAO international flight plan form? I’ve seen one wrong mark on this form ground a flight for hours.

Costs. Landing, ramp, and other fees can be dramatically higher in foreign countries than in the United States. This extends to things like catering, water & lav services, and even plain old ice. In Geneva, an Italian pilot with whom I used to fly reported paying more than $1,000 to have a bag of ice delivered to the aircraft.

Ramp checks. You think having an FAA inspector ask for your pilot certificate and medical is bad? Try the European equivalent, a SAFA (Safety Assessment of Foreign Aircraft) check. A team of inspectors will crawl all over the interior and exterior of the aircraft, checking emergency exits, altimeters, flight recorders, navigation charts, emergency equipment, pilot training records, placards, and everything else you can possibly think of.

Accessibility. We take it for granted that you can fly VFR anywhere you want in the U.S., even at night. We can go to the busiest airports, and they are prohibited from discriminating against general aviation or any class of operator. Many countries do not allow VFR at night, single engine IFR, experimental aircraft, aerobatics, or GA flight over populated areas.

Don’t get me wrong, there’s plenty to love about international travel, but the process of flying abroad is usually far more expensive, slow, and cumbersome than it needs to be. If you’re the guy in the left seat, it’s best to take to heart the words of Chinese philosopher Lao Tzu, who prophetically stated that “a good traveler has no fixed plans, and is not intent on arriving.”

Though for very different reasons, whether I’m landing at home or abroad, I always end up thinking to myself, “What a country!”
