Windshield Heat
Asked a question about the use of windshield heat for an exam question, and the answers include,
1. Stop windshield fogging up on departure when climbing into warmer air,
2. Increasing strength of windshield incase of a bird strike.
Had a look through various technical notes and also aircraft flight manuals but can't find any reference to the bird strike bit.
Have a recollection of somebody mentioning that in some of the first generation jet's the winshield heat was turned on for that purpose.
