I’ve been on the hunt since AirVenture for evidence that ADS-B is really the future of air traffic separation and services. And, having flown from south Florida to Lake Superior, to Kalispell, Montana, and back, I’ve got news.
Aviators are adopting ADS-B. Not in droves, mind you, but being ADS-B equipped myself, I can see the other ADS-B aircraft on my display screen, and there are more of them than ever before. Along the entire trip there was only an hour in Wyoming, at low altitude, where I did not have ADS-B coverage.
No, we aviators are not keen on dropping money for avionics we aren’t certain we’ll be required to use. I mean, we resisted Mode C until the veils were dropped over Class B airspace and spun down to the ground (I actually know a couple of anarchists out there still flying Mode A transponders).
ADS-B is particularly problematic because the specs kept changing. They are, according to the FAA, set in stone now, though. For aircraft operating above 18,000 ft and/or outside the U.S. a Mode-S ADS-B transmitter (1090ES) is needed. If you stay in the U.S. and below Class A airspace you can stick with a UAT transceiver. Of course, we’ve seen stone change, too. And ADS-B is not without its weaknesses. That said, the most recent interaction I had with the FAA was on point–adapt, or you’ll be left out of controlled airspace above 10,000 ft and Class B and C airspace, they told me. On January 1, 2020. The date’s not moving. That’s the FAA’s story and all manner of individuals I spoke with are sticking to it.
These kinds of rock-solid statements by the FAA have begun to bring consternation to the people who run the avionics companies. Why? Because with less than five years left to meet the mandate, they know it will be a struggle to equip all of the aircraft in the U.S. that might need this technology with this technology.
There are only so many avionics shops. And when it comes to the higher end equipment, business jets and helicopters sporting integrated digital avionics, for instance, there are even fewer designated service centers that can handle the job. Really, though, that isn’t the crux of the problem.
At the core of the problem are older high-end integrated panels. A TSO authorization, issued in accordance with 14 CFR 21 subpart O, is not required to upgrade them. Yet, ADS-B Out systems and equipment installed or used in type-certificated aircraft must have a design approval issued under 14 CFR 21 (or must be installed by field approval, if appropriate). To upgrade these legacy avionics is proving to take far too long. That’s a lot of lost revenue and inefficiency for the companies, mostly small-to-medium businesses, that own them. And that is before the cost of equipping is considered in the mix.
Some OEMs are actually trying to persuade these aircraft owners to trade up to ADS-B and ADS-C equipped aircraft–new aircraft. Great idea on the surface, if it wasn’t for the economy. Companies are cautious after 2008. They are not easily coaxed into new acquisitions. They might be more easily convinced by their own finance departments to shed the flight department altogether instead of buying new equipment–something they did in droves in 2008-9.
Back in my light airplane world the news is not quite as bad, until you get to older light aircraft, that is. No one wants to put 10 percent or more of the value of the airplane back into the avionics, particularly for one key piece of equipment.
And experimentals? They had the advantage of being able to use less expensive, non-Compliant ADS-B boxes, until recently. The FAA is now telling us that as of January 2016 those early transceivers will no longer receive accurate traffic information. Yes, the FAA is going to make flying LESS safe for those users, at a time when there are still hardly any users on the new system. All without proving that the non-Compliant boxes are a hazard.
I think it is time to get the pens out and start complaining, to your congressman, to your local FSDO, to the FAA at 800 Independence Avenue. There are a lot of good things about the way ADS-B can change our National Airspace System, but recent declarations from the FAA have me feeling squeamish about the execution of the transition to this new system. What do you think?
