Slaying the dragon

Tuesday, August 26th, 2014

Regardless of what helicopter you are flying, whether it’s the Robinson R22, Bell JetRanger, or any helicopter for that matter, you need to be comfortable with autorotations. At our flight school we have broken the auto in to three flights. If you’re a CFI reading this, try it. If you’re the student or certificated pilot looking to get proficient, ask for it.

Start with talking on the ground, sitting in the helicopter, and going through the physical motions. Move the controls the way you would actually respond. If you are the CFI, play the whole thing down (mentally) and don’t let the student get beaten before they even lift off. If you are the client/student try to put past bad experiences with autos behind you.

First Flight: Auto-rotative decent. Climb to at least 3,000 feet. I like even higher. The only thing you want at first is RPM control. There is plenty of time to adjust airspeed. RPM is the constant in most cases. Climb back up and then try adjusting the airspeed all the way through the decent from 30-70 knots, noting what cyclic control movements do to the RPMs. Get comfortable with controlling RPM with mostly cyclic movement. The ONLY thing you want to achieve by the end of this lesson is comfort with RPM and airspeed control in the decent.

Second Flight: I like to start with quick stops from 50 feet and 60 knots, which is very similar to the flare in an autorotation. End this lesson with auto-rotative descents, followed by a flare (quick stop). Join the needles (rotor and engine RPM) very early so it seems just like the two maneuvers put together. By doing this you’ve learned to join the needles at 300 feet AGL, and not in the flare where most over-speeds occur. End this lesson being comfortable with descents and the flare.

Third Flight: Go over all three maneuvers and then combine them all together. Join the needles a little further down the line each time. Don’t be crazy about that; the auto looks the same regardless of where you join the needles.

If you want to accomplish full down autorotations, add a fourth lesson of hovering autos and run-on landings, which will be the same as a touch down from zero ground speed or from 15-20 knots if you are unable to zero out the ground speed.

This should build your confidence and make it fun, regardless of what helicopter you are flying.

Oshkosh or bust

Thursday, August 14th, 2014

I’m forever spoiled. Everyone talks about flying an airplane to EAA AirVenture in Oshkosh, Wisconsin, but arriving in a helicopter is a far better experience. I’m burdened with knowing this now, thanks to Sporty’s Pilot Shop’s John Zimmerman, my ride to the show this year.

 

John owns a beautiful R44 he flies for fun and the occasional work purpose. Being a gadget geek, his is kitted out with a Garmin 430, a handheld Garmin 496, and that day we were carrying two iPads, and Sporty’s new Iridium Go! satellite hotspot. It also has air conditioning, which is a luxury well worth having. So while many would scoff at the suggestion that a helicopter is a cross-country aircraft, with some nice instrumentation and create comforts, it turns out to be well suited to the task.

 

The trip started with an early morning airline flight to Cincinnati, where I met John. The first two miles were over the eerily quiet Cincinnati-Northern Kentucky International Airport. The helicopter proved to be a good vantage point to see the juxtaposition of miles upon miles of runways for the dozen or so regional jets parked at the various terminals.

 

From there it was another 348 miles on to Oshkosh, including two stops. Since helicopters and their pilots are most comfortable at lower altitudes, trips like this are a joy. The world isn’t going by very fast, which leaves that much more time for taking it all in. Lounging around at 75 knots groundspeed, the trip took more than four hours, but it felt like much less.

 

The best part of the trip, and what airplane pilots miss out on, is the arrival to the show. In an airplane there is a mass convergence on one spot southwest of the airport as everyone forms a line and heads in. You have to listen closely to air traffic control, respond quickly, and follow the controller’s directions precisely. The arrival procedures in a helicopter are much more civilized. Simply listen to ATIS, monitor the tower, maintain 1,800 feet, and land. Transients can park at Pioneer field, outside the main show site. From the time we shut down to the time our ride arrived was 10 minutes. There’s no walking, no humping heavy bags. They pulled off the main road and we jumped in and left. Clearly the folks at EAA know helicopter pilots, and the arrival suits them perfectly.

 

With the R44′s fuel-burn rate, and lackluster groundspeed in headwinds, it might not be the most efficient cross-country machine. It is, however, a lot of fun, which is all that matters when you are on your way to Oshkosh.
