Nimbus,
Thanks for the reply, which confirms my view, reinforced by my recent experience, that it's statistically pointless for a GA pilot transitting in UK to listen on 130.4.
Perhaps you might care to listen out on the nearest LARS frequency the next few times you fly and see just how busy our Class G airspace is.
As a glider pilot, you don't want any more equipment, I do fully understand the technical difficulties this would present. As you say, EASA may well require that gliders, in common with other small aircraft, carry more electronics in the near future.
To argue against further legislation, with any hope of gaining an exemption, the gliding fraternity would need to present a very strong case with a viable alternative. To propose that GA neglects its established and proven procedures to call on the gliding frequency would be untenable.
GA has by definition to avoid YOU but if GA has no idea you are there, how can they?
