17
Q

During a constant bank level turn, what effect would an increase in airspeed have on the rate and radius of turn?

Q

Conditions that determine the pitch attitude required to maintain level flight are

Q

Rate of turn can be increased and radius or turn decreased by

A

decreasing airspeed and increasing the bank.

20
Q

The primary reason the angle of attack must be increased , to maintain a constant altitude during a coordinated turn, is because the

A

Vertical component of lift has decreased as a result of the bank.
