Re: Crosswind application(s)
ToPocHi
The simple formulae behind the clock method can be used to determine the crosswind component in reverse if you have a drift indication on your instruments.
Drift angle multiplied by groundspeed in nm/minute = crosswind component.
e.g. Drift = 8 degrees, GS on approach = 150
Crosswind component = 8 x 2.5 = 20kt.
Useful if ATC have passed the wind on the field, use clock method to determine crosswind for landing. Check crosswind component inbound e.g. 1500ft. If there is a significant difference there may be a bit of shear on the approach.
