Quick Crosswind Calculation



A little geometry/trigonometry goes a long way...

30 degree crosswind... multiply by 0.5 to get the crosswind component

eg wind 30 degrees off runway heading at 20 kts x 0.5 = 10 kts

45 degree crosswind... multiply by 0.7 to get the crosswind component

eg wind 45 degrees off runway heading at 20 kts x 0.7 = 14 kts

60 degree crosswind... multiply by 0.9 to get the crosswind component

eg wind 60 degrees off runway heading at 20 kts x 0.9 = 18 kts
