What is a common effect of improper flight coordination?

Improper flight coordination leads to an unstable flight path due to the incorrect balance and use of the aircraft's control surfaces. This can happen when the pilot does not properly coordinate the ailerons and rudder during maneuvers, particularly in turns. When a pilot rolls the aircraft to initiate a turn without applying corresponding rudder input, it can result in adverse yaw; this causes the aircraft to yaw away from the intended turn direction, disrupting stable flight. The resulting instability can lead to increased drag and potential loss of control, manifesting as easier entry into stall conditions or even spins if not corrected. Thus, maintaining proper coordination is crucial for keeping a stable and controlled flight path.
