A rotorcraft gauge display prioritization system for a rotorcraft of a type having at least one engine component, at least one gearbox, first and second sensors and a single-output gauge, the system comprising: a priority engine configured to: receive a first measurement from a first sensor associated with an engine component of the rotorcraft and a second measurement from a second sensor associated with a gearbox of the rotorcraft; select a prioritization criterion based on at least the received first and second measurements from the first and second sensors, and select, without user input, one priority measurement for display from the received measurements based on the prioritization criterion selected by the display prioritization system, the one priority measurement representing an operating level or value associated with a respective one of the engine component or the gearbox of importance to the pilot; and an output engine configured to instruct a single-output gauge disposed within a cockpit to display information representative of the one priority measurement selected by the display prioritization system without user input to the pilot such that the gauge displays only the information representative of the one priority measurement and does not display information representative of any other received measurements so that all of the sensor measurements from the engine component and the gearbox are combined into the single-output gauge. a priority engine configured to: receive a first measurement from a first sensor associated with an engine component of the rotorcraft and a second measurement from a second sensor associated with a gearbox of the rotorcraft; select a prioritization criterion based on at least the received first and second measurements from the first and second sensors, and select, without user input, one priority measurement for display from the received measurements based on the prioritization criterion selected by the display prioritization system, the one priority measurement representing an operating level or value associated with a respective one of the engine component or the gearbox of importance to the pilot; and receive a first measurement from a first sensor associated with an engine component of the rotorcraft and a second measurement from a second sensor associated with a gearbox of the rotorcraft; select a prioritization criterion based on at least the received first and second measurements from the first and second sensors, and select, without user input, one priority measurement for display from the received measurements based on the prioritization criterion selected by the display prioritization system, the one priority measurement representing an operating level or value associated with a respective one of the engine component or the gearbox of importance to the pilot; and an output engine configured to instruct a single-output gauge disposed within a cockpit to display information representative of the one priority measurement selected by the display prioritization system without user input to the pilot such that the gauge displays only the information representative of the one priority measurement and does not display information representative of any other received measurements so that all of the sensor measurements from the engine component and the gearbox are combined into the single-output gauge.
