You turn on pitot heat this time of year?


Anytime there is visible moisture in the air.

Even when it is 80 F degrees? That is simply a waste of electrical
energy.

Flying on board a Beech 1900 DFW-ELD about three months ago outside temp on
the ground 85 descending from 17000 I watched ice form on the leading edge
of the wing and on the spinner. It wasn't completely gone until we descended
through 13000.
