Max drift calculation

[BEagle]

See: http://www.pprune.org/forums/showthread.php?t=208745

Max drift = Wind velocity / (TAS in miles per minute)

Then apply the relevant 'clock factor' - i.e. if the angle between the wind and track is 15 deg use 1/4 max drift, 30 deg use 1/2 Max drift, if it's 45 deg, use 3/4, 60 or more use all of it.

Unfortunately you will read nonsense such as '3 deg per 5 kt' - please ignore that and use the correct method as described above.
