Does head position affect pilot wound chances?

[Latrobe]

If I were to be looking back at the plane shooting at me would I have a higher chance of being pilot wound than if I was looking straight ahead, keeping the armor plating between me and the bullets? Or is the pilot stationary in your plane no matter where you are looking?

Yes.
Head positions, jumping to different stations and so on just changes your point of view, nothing else.
