Angle de correction de cap

L' angle de correction de cap (également connu sous le nom d' angle d'ajustement de cap ) est l'angle qui doit être appliqué au cap actuel d'un avion pour corriger les erreurs de navigation ou les écarts par rapport à la trajectoire de vol souhaitée. Il est généralement utilisé lorsque l'avion s'écarte de sa trajectoire en raison de facteurs tels qu'une dérive du vent, des imprécisions de navigation ou un cap incorrect.

This angle is calculated by considering:

1. Wind Drift: If the wind is pushing the aircraft off its intended course, the course correction angle will be the angle required to counteract the wind’s effect and bring the aircraft back on the correct path.
2. Current Heading and Desired Course: The angle between the aircraft’s current heading and the intended course path determines how much correction is needed.
3. Magnetic or True Heading: Depending on the reference system being used, the correction might be relative to magnetic or true north.

For example, if a flight is supposed to fly on a heading of 090° (east), but winds are pushing it to the south, the course correction angle will indicate the new heading (e.g., 080° or 100°) to maintain the correct track.

In practice, pilots use tools like flight management systems (FMS), navigational charts, or manual calculations to determine the course correction angle during flight, ensuring they stay on the correct route despite deviations.
