Plain English Meaning
Small adjustments the pilot makes with the controls to put the airplane back on the path they meant to fly.
Full Definition
Control inputs made by the pilot to adjust the airplane's track over the ground or its path through the air so that it matches the intended path. In ground track work, these corrections compensate for the effect of wind drift to keep the airplane following a planned line over the ground.
Context Anchor
Seen when learning drift and ground track control, especially while using outside visual references to keep the airplane following a planned line over the ground.
