Couple of PANS - engine stopped on a dH82a during a stall turn and did not restart on the dive, sorted my field then put out the Pan AFTER I had the landing planned, definitely the way round to do it.Next was uncertain of position over Wales, in IMC and getting no VOR reception - headwind had increased from the forecast 40kts to 60!
My one Mayday was actually the FO calling it on taking a Swan through an A330 engine getting airborne from Glasgow, PAN would have been fine, but I have no problem with someone calling a Mayday instead, better that way round than Pan when it should be Mayday!
