Question

What is the incidence angle in the yaw plane called?

(a) Side slip angle

(b) Yaw angle

(c) Crossflow angle

(d) Angle of crosswind

This question was posed to me at a job interview.

Asked question is from Fly-By-Wire Technology in portion Fly by Wire Flight Control of Avionics

Answer 1

Right option is (a) Side slip angle

The best I can explain: The angle of incidence in the yaw plane is known as the side slip angle. It is the angle between the direction the aircraft is travelling and the direction its nose is pointing. When the side slip angle is high the aircraft is not in a coordinated turn and hence is flying inefficiently.
