Question

What is the grazing angle?

(a) Smallest angle between pilot’s line of vision and the cockpit windscreen

(b) Same as over nose angle

(c) Seat back angle

(d) Seat reference angle

I got this question during an interview.

My question comes from Crew Station in chapter Crew Station, Passengers, and Payload of Aircraft Design

Answer 1

Correct option is (a) Smallest angle between pilot’s line of vision and the cockpit windscreen

For explanation I would say: The transparency grazing angle is defined as the smallest angle between pilot’s line of vision and the cockpit windscreen. It is not same as the overnose angle. Seat reference point is defined as the point where seat pan meets back.
