Question

In a 45 degree banking turn, a UA will ___________.

1) Be more susceptible to spinning
2) Stall at a higher airspeed
3) Stall at a lower airspeed

Answer 1

In a 45 degree banking turn, a UA will stall at a higher airspeed due to the redirection of lift to create centripetal force, reducing the vertical lift that supports the aircraft's weight.

Step-by-step explanation:

When an unmanned aircraft (UA) or any airplane is in a 45 degree banking turn, it will stall at a higher airspeed than it would in level flight. This occurs because the lift vector is tilted during a bank turn, meaning a component of the lift that usually opposes gravity is now used to create centripetal force for the turn. As a result, more lift (and thus a higher speed) is needed to support the plane's weight and maintain altitude. When an airplane banks, the pilot must increase the angle of attack or speed to compensate for the loss of vertical lift component. Failing to do this can result in a stall because the wings are no longer producing enough lift to support the aircraft at the original airspeed.
