How do you determine heading and track when wind data is available?

• A. Ignore wind and fly by heading only
• B. Ground speed is the only consideration
• C. Wind does not affect heading
• D. Use wind vectors to determine track and heading, applying wind correction angle

Answer: (D)

When wind data is available you determine heading and track by combining wind and aircraft motion as vectors. The aircraft’s nose points in the heading you set, while the wind pushes the aircraft over the ground, producing a ground track. To fly a desired ground track, you apply the wind correction angle—the angle between the desired track and the actual heading needed to compensate for wind. In practice, you choose a heading that, when the wind vector is added to the airspeed vector, yields the target ground track; the ground speed comes from the combined vectors. This approach keeps you on course and also gives you a realistic estimate of time and distance because wind affects both direction and speed over the ground. Ignoring wind, or focusing only on ground speed, would let crosswinds drift you off target, and saying wind doesn’t affect heading isn’t accurate because you must adjust the heading to counteract wind.
