Given the following information,determine the crosswind components (XWC), according to Mental Dead Reckoning (MDR)...
Magnetic track: 315°
Wind (magnetic): 015°/20 kt
Mental Dead Reckoning (MDR) crosswind component:
The XWC can be calculated using a “clock code rule”, where each 15° of wind angle is represented by ¼ of an hour – meaning ¼ the wind strength
Wind angle |
15° |
30° |
45° |
60° |
% of wind speed |
25 |
50 |
75 |
100 |
(wind angle is the angle between the wind vector and the track/runway direction to the nearest 10°)
- In this case, the angle between the wind vectpr and the track equals 60°. Therefore, based on the table above, we can conclude that the crosswind component equals 100% of the wind speed ⇒ 20 kt.
