Claim:
1. An upgraded preexisting flight management system (FMS) having increased functionality over a preexisting FMS, the preexisting FMS comprising: a legacy advanced flight management computer (AFMC) having aircraft performance capabilities exploitable throughout a flight of an aircraft having the preexisting FMS on board the aircraft, a legacy inertial reference unit (IRU) configured to measure navigation data, a legacy central air data computer (CADC) configured to compute data associated with the flight of the aircraft, a legacy distance measuring equipment (DME) receiver configured to measure distance based on radio signals, and a legacy digital flight guidance computer (DFGC) configured to manipulate guidance information, wherein, the legacy IRU, legacy CADC, legacy DME receiver and legacy DFGC are connected to the legacy AFMC, the upgraded system comprising: the upgraded preexisting FMS being capable of at least increased navigation database storage capacity, as well as required navigation performance (RNP), vertical navigation (VNAV), area navigation (RNAV) and required time of arrival (RTA) capability utilizing a GPS based navigation solution, while still enabling the legacy AFMC to exploit its aircraft performance capabilities throughout the flight of an aircraft having the upgraded preexisting FMS on board.
