Use the sliders to set the forecast wind and aircraft airspeed
The boxes over each compass point show the calculated wind correction and groundspeed for a given set of conditions
Wind Direction = 150°
wind speed = 25kts
True airspeed = 100kts
1. To fly a track of 225°, for 25nm:
Wind correction angle = -14°, groundspeed = 91kt.
Result: fly heading of 211° for 19mins
2. To fly a track of 315° for 25nm:
Wind correction angle = -4°, groundspeed = 124kt.
Result: fly heading of 311° for 14mins
