- Runway Crosswind -
Enter Runway Heading, Wind Direction in degrees (°) and Wind Speed in Kts into the form.
Colored warnings will be shown when head-, tail- or crosswinds exceed 15 or 20 kts and wind angles greater than 45 ° and 60 ° .
Rule of thumb: with a 30 ° wind angle the crosswind is 50% of the wind speed; at 45 ° the crosswind is 70%; over 60 ° the crosswind is 100%.
