A few of my colleagues and I had discussions with management in the past about the 365, its data only went up to +40c, when asked to fly the aircraft on +40 c days we refused stating the manufacturer had no performance data for above 40c, ie weight limits, etc.
They stated that as soon as you get airborne you are ascending into cooler temperatures, I said, yes, but you have to land sometime, and if its over 40 c and I mush in, im for a row of outhouses. Dauphins don't like the hot temperatures, and my right boot isn't big enough to hold the pedal all day <img src="wink.gif" border="0">
