When flying a desired ground track, crabbing the aircraft into the wind is a means to compensate for what?

Crabbing the aircraft into the wind is necessary to compensate for drift. When an aircraft is flying in a crosswind, the wind can push the aircraft off its intended ground track, causing it to drift to one side of the desired path. To maintain the desired ground track, the pilot must angle the aircraft’s nose into the wind, which is referred to as "crabbing." By doing so, the forces from the wind are counteracted, allowing the aircraft to progress in the intended direction while still flying straight ahead.

Drift occurs because the aircraft's actual path over the ground can differ from its heading due to lateral wind forces. Without compensating for this drift, the aircraft would end up flying off course, which is why understanding and effectively applying crabbing techniques is essential for accurate navigation and positioning over the ground.
