All,
While building, I'm flying a Grumman Tiger (it's almost a certified RV-9A) in a club. It seems that our club's not-so-old Bendix King KT73 mode S transponder is dying. It's an orphan with a flat rate repair fee of $3000. Considering we can buy a new ADS-B transponder with a WAAS source for not much more than that right now and that we would eventually have to cross that bridge, we're thinking it's time to pull the trigger on a 2020 compliant system.
So...which integrated transponder do we choose? The easy option is Garmin's GTX 335 with internal WAAS. Presently, we don't need ADS-B in as three of us pooled our money and bought a Stratus 2s. We love it, it's great. Reading up on ADS-B in and out on an FAA site I'm concerned about us getting "degraded" ADS-B in service even though we would be compliant. There's a thread somewhere on VAF about this, too.
With the Garmin, I THINK the system would see us as two clients. One would be our Stratus for ADS-B in that would show SIL=0 and the other would be the GTX335. In this instance, I don't think the system would give us all the benefits that are meant to come with ADS-B.
Another option is Appaero's transponder, but that makes me nervous as I don't know how long Appaero will be around and it seems silly to buy a panel mount device because we have a portable (and likely consumer grade) piece of electronics.
The third option is buy the GTX 345 and sell the Stratus. It apparently works with Foreflight.
Does anyone have any insight into the ins and out of IN/OUT?
