摘要
In a flight management system (FMS) of an aircraft, there is included a speed generator that outputs a speed command for the aircraft in accordance with a preselected mode. The FMS further includes an apparatus performing a method for adjusting the speed to achieve a desired arrival time. The apparatus comprises a unit for generating a speed adjustment coefficient (KSA), a unit for calculating wind forecast error, and a unit for adjusting the command speed outputted from the speed generator. The adjusting unit utilizes the KSA, actual wind speed at the current aircraft position, and wind forecast error at the aircraft position. The speed adjustment compensates for the error in the wind forecast, in order to achieve the desired arrival-time.
