We have increased glider activity in Snowdonia right now. Most (but not all) of them have FLARM fitted. Whilst flying in an ACM sortie yesterday we met one of the few non-FLARM gliders at about 12000'. He clearly didn't show up on TCAS, wasn't visible to Swanwick and wouldn't have shown on the FLARM screen even if we'd been able to see it in cockpit.
Can someone please explain how this system is supposed to help us?!
