A question for someone with transponder and PCAS experience:
How do the collision avoidance systems respond to transponder
equipped gliders in a gaggle, or transponder equipped tow planes?

I only have experience with 2 installations in gliders:
1. Transponder equipped, no collision avoidance system.
2. FLARM.

Searching for the next installation, hoping it can consume little
power, integrate with power traffic, and behave as well as the FLARM.
