If the Glider had had £390 worth of PCAS he would have “seen” the Tutor (assuming it had a transponder. If the BGA encouraged the fitting of Flarm and PCAS and the rest of us fitted Flarm and PCAS we would all be £1000 less well off but much less likely to fly into each other. I am hoping to test a Flarm in my MCR very soon (will report back) and already have PCAS. Collision avoidance which combines detection of Flarm and Transponders is less than 12 months away.
Flarm has a range of 3 - 5km (according to the manual), my PCAS is set to 5nm.
