QUESTION: Should I place reflective heat shields in the windshield of my BE200 when I leave it parked on the ramp?
ANSWER: Unlike your car, the windshield of the King Air has a polyvinyl layer sandwiched between two plates of glass. Using sunscreens to reflect the heat back outside the cockpit can damage this inner layer of the windshield. Of course, this can lead to premature failure of the windshield. So my advice is not to use them.
