Gliding areas.
I've been for a bimble this afternoon over to Skeggy and up the coast to Mablethorpe. On turning west at Mabby I was told by the zone I was on (no names no pack drill) that I was infringing Strubby glider field's Notamed area. I was actually about a mile outside, not a lot I know but I was visual with Strubby and the gliders pootling around.
It wasn't a problem, no offense taken or anything I just headed further north but I was wondering if ATC designates a larger area to glider fields than is actually on the half mil map and GPS? And yes I'm much aware of glider fields and the dangers thereof, I'm also a glider pilot.
