What occurs to the radius of a turn if the airspeed is decreased during a coordinated level turn?

• A. The radius remains unchanged.
• B. The radius decreases.
• C. The radius increases.
• D. The radius fluctuates.

Answer: (B)

When the airspeed of an aircraft is decreased during a coordinated level turn, the radius of the turn decreases. This phenomenon can be explained by the relationship between speed, bank angle, and turn radius in aviation. In a coordinated turn, the aircraft generates a horizontal lift component that acts as the centripetal force needed to maintain the turn. The formula that connects these elements can be summarized as follows: the radius of the turn decreases as the speed decreases, provided the bank angle remains constant. This is due to the fact that a lower airspeed requires a smaller radius to maintain level flight during a turn, as the centripetal force needed is less when the aircraft is traveling slower. Therefore, reducing the airspeed causes the aircraft to turn more sharply, resulting in a smaller turn radius. This is crucial for pilots to understand, as managing speed effectively allows for better handling and control of the aircraft during flight maneuvers.
