A slip will result when which of the following occurs?

A slip occurs when the aircraft is not aligned with the relative wind during a coordinated turn, resulting in a sideways motion through the air. This situation typically arises when the aircraft is banked and there is insufficient use of rudder to maintain a straight flight path, leading to a condition where either the aircraft is skidding, or the turn radius is too tight for the amount of bank being applied.

When both the appropriate amount of bank angle and rudder input are not achieved, the airplane can enter a slip condition. This is particularly relevant in scenarios where some degree of yawing occurs relative to the direction of the turn, resulting in reduced aerodynamic efficiency and control.

In this context, understanding that both B and C contribute to the occurrence of a slip aids in grasping the dynamics of flight and aircraft control during maneuvers, emphasizing the importance of coordination between roll and yaw inputs during turns. Maintaining proper coordination is crucial to avoid slips, thereby ensuring safer and more efficient flight.
