constant altitude - correct answer ✔✔For a specific angle of bank and airspeed, the rate and radius of
turn will not vary.

produced at the higher speed will be - correct answer ✔✔four times greater than at the lower speed.
Load factor is the lift generated by the wings of an aircraft at any given time - correct answer ✔✔Divided
by the total weight of the aircraft

on the wing

knots? - correct answer ✔✔96 knots
One of the main functions of flaps during the approach and landing is to - correct answer ✔✔provide
the same amount of life at a slower airspeed
