If the rumour about operating UAVs is correct, any FTO should be aware that this will severely impede their flying. UAV and manned aircraft flying do not mix. Flying of large UAV (Predator, Reaper etc) will require a complete suspension of manned aircraft flying during arrival and departure. Maybe a re-think about moving out of Caernafon might be a good idea?
Back in the good old days (1990), I recall sitting as a passenger in one of RAE's Navaho Chieftains, heading in to land at Llanbedr, when we asked to hold. As a result we had the best seat in the house to see a Jindivik take off.
