1. A system for translating one or more alert signals into an auto flight system (AFS) maneuver comprising:

  • an emergency system configured to supply one or more alert signals, the emergency system including a traffic collision avoidance system (TCAS) and an enhanced ground proximity warning system (EGPWS);

    a plurality of aircraft flight control actuators;

    an AFS in operable communication with, and configured to control, at least the aircraft flight control actuators; and

    a processor in operable communication with the emergency system to receive the one or more alert signals therefrom, the processor also in operable communication with the AFS, the processor containing a first module, a second module and a state machine and configured to receive a time signal,the first module configured to cause the processor to;

    decode the one or more alert signals,validate the one or more alert signals,determine a maneuver definition that is associated with the one or more alert signals, andconstruct one or more AFS mode commands from the maneuver definition that when executed in combination direct the AFS to perform the AFS maneuver;

    the second module configured to cause the processor to;

    execute the one or more AFS mode commands determined from the maneuver definition by selectively arming one or more standard AFS modes required to implement the AFS maneuver; and

    the state machine coupling the first module to the second module, the state machine configured to cause the processor to coordinate a function of first module with that of the second module based on the time signal,wherein the state machine comprises at least an Inhibit Active Maneuvers State, a Ready State, a Maneuver in Progress State, and a Maneuver Exit State.
