What effect does raising a wing in a turn have on the bank angle?

Increases the turn radius.
Decreases the turn radius.
Increases the stall speed.
Decreases the lift.

The correct answer is: Increases the turn radius.

When a pilot raises a wing in a turn, this action effectively increases the bank angle of the airplane. As the bank angle increases, the aircraft's turn radius also increases. This is due to the relationship between bank angle and centripetal force; a greater bank angle results in a tighter turn due to the increased load factor, allowing for a larger turn radius. Conversely, a lower bank angle would result in a smaller turn radius, as less lateral lift would be required to maintain the turn. The physics of flight dictates that as the bank is increased, more lift is needed to counteract the weight of the aircraft and maintain altitude, which can sometimes contribute to performance issues such as an increased stall speed if the angle increases too much without proper management. Thus, raising a wing leads to an increase in bank angle, which, in turn, results in an increase in the turn radius.
