In one embodiment, a vehicle prognostic and diagnostic system comprises: a vehicle maintenance computer (VMC) for prognosis and diagnosis of faults; a vehicle operations network (VON) providing a communications link between the VMC and vehicle related processors; sensors communicatively coupled to the VON providing sensor data relating to operations of vehicle sub-systems; a vehicle maintenance database communicatively coupled to the VMC providing vehicle maintenance information to the VMC; a transceiver coupled to the VMC, the transceiver selecting at least one data link from a plurality of data links for communication with a ground station. The VMC detects when a fault occurs or is likely to occur based on sensor data and the vehicle maintenance data. The VMC queries the database for mitigating action when it detects a fault occurs or is likely to occur. The transceiver uploads a message to the ground station when the database cannot provide mitigating action.
