Getting back to the original question...FLARM doesn't talk to anything other than another FLARM receiver. The RAF retro fitted FLARM to their Tutors for greater SA. A few years ago I was gliding over Oxfordshire when I saw a FLARM contact coming towards me a 1000' lower (a powered ac - this can be configured in the set-up), it was the BBMF Lancaster and the Canadian one with Spitfire and Hurricane escort. So yes to the question if you have the kit.
