Abstract
A method of determining the speed of the wind to be taken into account for determining a maximum authorized takeoff weight of an aircraft. A measured speed TASof the local wind is calculated from at least one current speed TASof the local wind and an observed speed TASof the local wind on the basis of weather observations and on the basis of a heading value. The measured speed TASis compared with the observed speed TASin order to determine a calculated speed TASof the local wind while also making use of at least one instability criterion of the local wind as supplied by the weather observations and weather forecasts. The calculated speed TASis then for taking into account in order to optimize the maximize authorized takeoff weight of the aircraft.
