TAS = 140Kt, True HDG = 302, W/V 045(T)/45kt, calculate drift angle & GS

Crosswind Component = W x Sin (diff between Track and W/V)
= 45 x Sin (103)
= 43.8kts
Head wind Component = W x Cos (diff between Track and W/V)
= 45 x Cos (103)
= -`10 kts.......- stands for Tail wind
so Gs will be TAS +(Headwind comp)= Ground speed

140+(10)=150Kts

drift angle
Tan(theta)= Crosswind component/TAS
= 43.8/140=17.13deg

Wind is from around 5 o clock...therefore ur drifting left i.e. 17Left

i don't care what are the options..these are the accurate figures
