Drifty angle is the angular difference between where the airplane’s nose is pointing (heading) and the actual path it follows over the ground (track). The heading is the direction the aircraft is oriented relative to true north, while the track is the direction of its movement over the ground. Wind pushes the aircraft, so the track can be off from the heading, creating this drift angle.

Among the choices, the pair that represents a directional difference is true heading and track. The other options mix speeds (true airspeed vs ground speed) or involve different concepts (track vs variation, or heading vs course, which is a wind‑correction concept rather than drift).
