A method of assessing the effect of wind on the aircraft drift from track.
MAX DRIFT - The maximum drift an aircraft will suffer from a wind directly abeam the flight path. This is estimated by taking the windspeed and dividing it by the aircraft’s speed in nm / minute.
E.g. An aircraft flying at 240 kts is covering 4 nm / minute. With a wind from directly abeam with a speed of 20 kts the aircraft will suffer a drift of 5˚.
20 / 4 = 5
