912ULS Temp in Vegas

Hi Joseph,

Here in Australia, summer day temps can rise to 45C+ (113F) in the middle of the day.

Part of my Rotax engine management, is to schedule my flying to avoid the heat of the day.

If hot weather is forecast, I start my flying at first light, with the aim of being on the ground, when temperatures get much above 35C (95F).

I find being on the ground, in a small aircraft (low wing), above 30C (86F) the cockpit is turning into an oven. This coupled with engine temperature concerns on TO/Climb Out and the inevitable convective turbulence, that start to appear by late morning, means that this period is not fun/best avoided (great for glider pilots).

We have the same day time temps in Arizona too, but we still fly just after sun up. If I fly in the middle of the day it's  flying  high and taking off flatter and at a faster speed to help cowl air flow.
