Hi Piperboy
drop in at Feshiebridge (Cairngorm Gliding Club) some weekend! (PPR). Nice strip - but not in Easterlies though!
Watched a series on army helicopter pilots training once - they were flying in Snowdonia and the trainee commented - "Lots of downdraught here" - well duh, yes, on the lee side of a big ridge!
Rotor is even more to be avoided!
