Transponders & Portable Collision Avoidance Systems.
Wondering how hard would it be to have an additional mode on a transponder.
Auto response mode where the transponder sends its info without being interrogated.
Aim is to provide transponder pulses for other aircraft's PCAS to detect.
Perhaps when in auto mode it starts auto sending after 1 min without interrogation and then auto transmits every 30 secs until interrogated.
Would mean a Zaon PCAS would be useful anywhere, even out side or below Secondary SurveillanceRadar (SSR) coverage.
Rather than modify the transponder, a small device could be made which listened for your transponder responses & if none for a minute it would send its own interrogation signal. Being right alongside the transponder, the devices 1030Mhz interrogation signal would to be very low level.
Just what we need for the Birdville races to keep the Dr's Bonanza away.
