Given a true course of 105° and a true heading of 085°, what is the wind direction and speed?

To determine the wind direction and speed from a true course and true heading, one must consider the difference between the true heading and true course due to the wind's effect on the aircraft.

In this scenario, the true course is 105° while the true heading is 085°. The difference between these two values indicates the direction of the wind. The aircraft is heading at 085°, but due to the wind, it is actually on a course of 105°. The wind is therefore pushing the aircraft to the right of its heading, suggesting that the wind is coming from the northeast.

To calculate the wind direction, you can take the true heading and the true course, then find the wind direction. Since wind is conventionally reported as coming from the direction it originates, you can use the fact that a 20° difference from the heading to the course indicates the wind is effectively coming from around 020° (085° - 20° = 065°, but since it pushes the aircraft right, we consider it from the opposite direction).

Furthermore, to calculate wind speed, it's common to reference the change in ground speed derived from the heading and course alongside the indicated airspeed (not provided in this question). However, typical calculations might
