Deice fluid freezes if the temp gets low enough (below about -40 but
check this). Flaps wont come up due to being frozen etc.

It could be all kinds of things. My airplane has high and low start
restrictions and an absolute temperature limit. The start restrictions are
based on the possibility/probablility of a hot start and the absolute
temperature limit is based on the fuel gelling.

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?
