PT6 operations
I need advice from experienced PT6 (King Air E90 especially) operators on the use of windscreen anti ice and ice deflectors.
Is there a benefit in operating the windscreen heat in temperatures above freezing in order to improve birdstrike protection? Is there any adverse effect by doing this?
Is there a benefit in having the ice vanes open during a normal takeoff/landing on a gravel strip or on a sealed runway in temperatures above freezing?
