The present invention relates to a method to determine a wind speed considered to determine the maximum take-off weight for an aircraft (10). A measured speed (TASmes) of local wind is calculated from an observed speed (TASobs) of the local wind based on a flight direction value, weather observation, and at least one current speed (TASinst) of the local wind. The measured speed (TASmes) is compared to the observed speed (TASobs) to determine a calculated speed (TASperfo) of the local wind while using at least one instability standard of the local wind such as being supplied by weather observation and weather forecast. The calculated speed (TASperfo) is considered to optimize the maximum take-off weight for the aircraft (10). |
