Flight Management System Having Performance Table Datalink Capability

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.
