Many GA a/c are restricted to operations above a certain temperature. In my
case (Zlin 242L) the restriction is -20C at sea level and goes down to -40 C
(or F) at 9000 feet. But, the POH doesn't say why. Anybody know?

A recent thread on the Diamond Owners Website addressed the -20 degree
C limitation for the Diamond Star. According to Diamond, this is due
to temperature limitations on the avionics.
