Aerodynamics for Naval Aviators

We define angle of attack as the angle formed between the leading edge of
the wing and the relative wind.
The angle of incidence would be the angular difference between the
longitidunal axis of the airplane and a line drawn through the leading and
trailing edges of the wing.(Chord Line)

Isn't the "angle of attack" as defined above really the angle between
the chord line and the relative wind? The leading edge is a line in a
totally different direction.

You are right. Chord line is absolutely correct. (Senior moment :-)
