Bookworm:
... but when you demo the primary EoC you show them with the aircraft in the reference attitude (approx cruise) and then demo in a climbing turn that the elevator still affects pitch and that the rudder still yaws the aircraft left/right
from the pilot's perspective and irrespective of the aircraft's attitude.
How do you propose to use your flight dynamics definition of yaw reference in that situation and in a way that will add value to the poor old stude? One way may be to simply teach that the rudder cause the aircraft to sideslip left/right but that would be counter to (
AFAIK) all current teaching - it would also make terminology a bit tricky when teaching aeros.
IMHO (not so humble, actually
) this debate has moved from the practical to the esoteric. KISS for the stude's sake. All control effects are taught referenced to the aircraft's axes, piloting discussions should use the same reference frames.
