A method of controlling respective outputs of diverse types of crew interfaces (70, 400-450) for outputting visible, audio and tactile information to a human pilot for flight control of an aircraft, having steps of: receiving flight status information from multiple different sources, determining unified estimations of a current aircraft state and of a current phase of flight, based on at least the flight status information from the multiple different sources, generating respective coordinated visible, audio and tactile presentations for the diverse types of crew interfaces (70, 400-450), coordinated so that they provide mutually consistent indications of the unified estimation of the current aircraft state, according to the unified estimation of the current phase of flight, and causing the respective coordinated presentations to be output by the diverse types of crew interfaces (70, 400-450) to the human pilot; wherein the diverse types of crew interfaces (70, 400-450) comprising a visual type, an audio type and a tactile type, the visual type comprising at least one of: a head down display, a head up display and a head mounted display, the audio type comprising headsets or cockpit loudspeakers each optionally providing 3D audio, and the tactile type comprising at least one of: a throttle tactile output, a rudder pedal tactile output, and a stick tactile output, and the step of causing the respective coordinated presentations to be output comprises controlling these types of crew interface; and the step of determining the unified estimation of current phase of flight comprises determining the phase is one of: a take-off phase, a cruise phase, an approach phase, a touch down phase, a braking phase and a taxi phase. receiving flight status information from multiple different sources, determining unified estimations of a current aircraft state and of a current phase of flight, based on at least the flight status information from the multiple different sources, generating respective coordinated visible, audio and tactile presentations for the diverse types of crew interfaces (70, 400-450), coordinated so that they provide mutually consistent indications of the unified estimation of the current aircraft state, according to the unified estimation of the current phase of flight, and causing the respective coordinated presentations to be output by the diverse types of crew interfaces (70, 400-450) to the human pilot; wherein the diverse types of crew interfaces (70, 400-450) comprising a visual type, an audio type and a tactile type, the visual type comprising at least one of: a head down display, a head up display and a head mounted display, the audio type comprising headsets or cockpit loudspeakers each optionally providing 3D audio, and the tactile type comprising at least one of: a throttle tactile output, a rudder pedal tactile output, and a stick tactile output, and the step of causing the respective coordinated presentations to be output comprises controlling these types of crew interface; and the step of determining the unified estimation of current phase of flight comprises determining the phase is one of: a take-off phase, a cruise phase, an approach phase, a touch down phase, a braking phase and a taxi phase.
