After the deadline

[FlyingRon]

In fact, you MUST operate your transponder (if you have one) in controlled airspace.
The ADSB-required rules apply to what we used to know as the places you HAD to have a transponder/encoder before.

You should absolutely continue to use your transponder since it will make you visible to appropriately equipped aircraft.

Well, very few aircraft are "appropriate equipped" to see a simple transponder. What it does is make your position and altitude known to ATC radar which then can relay it via the various traffic information services as well as making it available to controllers. Still, you want it on.

The real elephant in the room will be getting the waiver to fly into ADS-B out airspace to verify system operation if and when one chooses to equip their plane after the deadline.

You don't have to fly within ADSB-required airspace, only airspace that has ADSB service coverage which is a much larger area.

Oops forgot the rule airspace requirement was for the rebate. My bad.

[Mayhemxpc]

yep. I will tell you how that works out. My plane is in annual right now and the ADSB Out transponder is being swapped out during that time. If things don't get done by Dec 31...and right now it looks like that won't happen I will find out about the waiver. My home airport in within the DC SFRA.

Yikes. I thought I was in an uncomfortable spot, being based 1/2 mile outside Atlanta's Class B ring, and with the new ADSB/TXP sitting in a box in my basement...

Gotta finish the RV-10, or at least get the fuselage to the paint shop, before I can spend any time upgrading the -6...

[Airmutt]

Hey Kyle, thought you were flying out of Cartersville. Did you move down to Pauling County???

We could spend quite a bit of time debating this to no purpose so I'll concede right away that if we are talking about single engine GA aircraft under $250k, none are equipped with TCAS/ACAS. My apologies. This misses the point.

The idea of not turning your transponder on because few of us have aircraft equipped to see that transponder is misguided at best. There are plenty of fast aircraft flying in non-ADS-B rule airspace that are equipped to see you so it's not just a "shall" as pointed out above, it's also a good idea.

In addition, as already stated while ADS-B towers do not interrogate mode A/C transponders, they do see the replies when these transponders are replying to interrogations by atc and ACAS/TCAS equipped aircraft. Those ADS-B towers then broadcast that information to all ADS-B IN equipped aircraft. Again it doesn't matter if no one around here has spent the extra $1k on ADS-B IN, those aircraft are out there and having your transponder on will at times make you far more visible to them.

No one advocated turning off mode A/C transponders especially since 91.215 specifically directs just the opposite.

I think you meant very few aircraft in your experience Ron. The majority of aircraft are TCAS/ACAS equipped, and many aircraft in uncontrolled airspace are TCAS/ACAS/PCAS equipped. In addition, ADS-B towers will repeat mode A/C replies so everyone with ADS-B IN can see these aircraft if something is interrogating them.

Therefore, those owners choosing not to upgrade mode A/C transponders with ADS-B should have their transponders on at all times in the air.
