Abstract: A system for monitoring the operation of an aircraft, especially a helicopter, includes data acquisition and processing components and display components which are able to display at least one indicator for at least one parameter relating to the operation of the aircraft. The system furthermore includes selection components which allow an operator to select at least one option for a specific configuration of the system, and components able to automatically configure, during the selection of at least one option, at least the data acquisition, processing and display components so as to adapt them to the selected option.

Abstract: The present invention relates to a method and a device (1) for assistance with the maintenance of an aircraft, especially of a helicopter, intended for replaying maintenance information. According to the invention, data relating to the operation of the said aircraft are recorded, with a view to their being replayed in the form of maintenance information, these data being accessible to a monitoring and visual display system (2) of the said aircraft, and only data capable of being visually displayed by the said monitoring and visual display system (2) are recorded with a view to presenting them to at least one pilot of the said aircraft.

Abstract: The present invention relates to a detection device comprising means (3) able to measure the value of a parameter, said device (1) being able to deliver values lying within a first measurement range which is limited at least by a first limit value. According to the invention, this device (1) furthermore comprises means (5) for modifying before delivery thereof any measured value so as to deliver a corresponding value which is defined in a second measurement range, said second measurement range being limited by at least a first limitation value which is different from said first limit value and which forms part of said first measurement range.

Abstract: A system for monitoring the operation of an aircraft, especially a helicopter, which automatically provides information which relates to the operation of the aircraft. Data acquisition and processing units centralize data relating to the aircraft together and group them in information pages. At least one information page contains a flight report of at least the latest flight of the aircraft, which simultaneously provides a flight number, flight duration, number of cycles of the engines, number of cycles of the turbine, and any appropriate message regarding detected faults and/or whether any of the aircraft's limitations have been exceeded. A display unit displays the information within the view of at least one pilot of the aircraft. At the end of a flight, a selection unit automatically selects a flight report which is automatically displayed by the display.

Abstract: A flight indicator for an aircraft, intended to give the power margin available on at least one engine of the aircraft as a function of the flight conditions. The indicator includes sensors (2, 3, 4) capable of delivering data relating to various monitored parameters of the engine, device (5) for processing the data coming from the sensors (2, 3, 4), and display device (6) showing, on a display screen (7) the processed data relating to that parameter among the monitored engine parameters, whose current value is closest to the limiting value for such parameter, each limiting value being established taking the ambient pressure (P0) and ambient temperature (T0) into account, in real time.
