Claim 15:
16. A system provided onboard an aircraft, the system adapted to verify an updated flight plan of the aircraft, the system including at least a flight management system and an avionics device external the flight management system, the flight management system and the device external to the flight management system both being provided on the aircraft, the system adapted to perform the steps of:
receiving, at the avionics device external to the flight management system, the updated flight plan from a source external to the aircraft,
receiving, at the flight management system, the updated flight plan from the avionics device external the flight management system;
generating, via the flight management system, a set of updated flight parameters comprising, at least one of a fuel usage or a flight time;
comparing, via the flight management system, the set of updated flight parameters with a set of current flight parameters to determine a difference in at least one of fuel usage or flight time;
generating, via the flight management system, a set of environmental conditions comprising, at least one of a weather pattern or an air-traffic pattern to define a set of received environmental conditions;
performing, via at least one of either the flight management system or the avionics device external the flight management system, a series of plausibility checks based of the comparing;
in response to the series of plausibility checks, automatically updating at least a portion of the flight plan if plausible or generating an indication if there is an implausible condition; and
operating the aircraft according to the updated flight plan.
