A flight management system which is capable of monitoring changes in airplane characteristics. The flight management system is configured with a datalink management function that enables the uploading of updated performance table data from a ground station via a datalink. Upon receipt of updated aerodynamic and propulsion performance data via the datalink, the flight management system creates or updates a set of airplane performance tables or curves in a database which can be utilized to compute more accurate flight profile and trip prediction parameters, such as estimated time of arrival and predicted fuel consumption quantity.

A flight management system which has access to customized information concerning the actual characteristics of a specific airplane or a specific fleet of airplanes of the same model when computing a predicted flight profile and associated trip prediction parameters. This up-to-date airplane-specific or fleet-specific information is digital data configured as a separately loadable database called a 'customized performance database'. This customized performance database contains a smaller set of performance data&#x2014;such as fuel flow correction, drag coefficient correction, and re-optimized speed/altitude tables&#x2014;than is contained in the baseline performance database. The flight management system will continue to use a baseline performance database as a 'limit' on the numbers computed using the customized performance database. The customized performance database can include tables or curves that are customizable by airlines.
