New Transponder Capabilities

[flybuddy]

I've currently got a Skyview and was considering adding either the SV-XPNDR-261 or 262. What would the value be in upgrading this from my current KT76C transponder? I have flown both TIS and ADSB equipped aircraft and have found the TIS to be fairly worthless in the small percent of targets it displays. Is there some future capability to the new transponders that may make this more worthwhile? I also see a Dynon note about needing the 261 over the 262 for possible 2020 ADSB compliance--why wouldn't the 262 comply if used below 18K and 175 knots? thx for any opinions..Tom

One of the most attractive features of our transponders for many builders is the elimination of panel space and cutout for a transponder, and allowing for control of the transponder through the SkyView display.

Current information from the feds indicates the Class 2 transponder will not meet the ADS-B Out mandate because of its lower transmission power.  The feds are designing the ADS-B system with geographical spacing of ground stations predicated on the transmission distance capability of the higher-power Class 1 transponders.

What constitutes Class 1 vs. Class 2 transponders?

Are you saying that you still think the more powerful new Dynon transponder will qualify for ADS-B Out?

What about ADS-B In?

Technically class 1 and class 2 have different TSO's. Functionally, the main difference is the output power (watts).

At this point, the class 1 transponder we sell meets all current requirements of the 2020 ADS-B out mandate. This doesn't mean that the FAA can't or won't change requirements, but there are no indications this will happen.

The transponder is not an ADS-B in device. These are never legally required in a plane, so you can use a totally experimental one. We don't have a solution in this area right now but do expect we will have something in this area in the future.

Dynon support,

Thanks for the clarification.
