The difference between the actual heading of the aircraft and its track over the ground is called angle of drift and need not be compensated for in order for the aircraft to maintain a desired track over the ground.

The statement that the difference between the actual heading of the aircraft and its track over the ground is called angle of drift, and that it need not be compensated for to maintain a desired track over the ground, is false. This is because angle of drift refers to the effect of crosswinds on the aircraft's flight path. When an aircraft is subjected to wind from the side, the heading (the direction the nose of the aircraft is pointed) may differ from the track (the actual path over the ground).

To maintain a desired track over the ground, a pilot must compensate for this angle of drift by adjusting the aircraft's heading. This compensation ensures the aircraft travels in the intended direction rather than being blown off course by the wind. Failing to make this adjustment can lead to significant directional deviations, which could affect navigation and potentially lead to safety concerns.

Therefore, recognizing and compensating for the angle of drift is essential for pilots to navigate accurately and maintain their intended flight path.
