Flight indicator with testing means for a helicopter

摘要

A flight indicator for an aircraft, intended to give the power margin available on at least one engine of the aircraft. The indicator includes sensors (2, 3, 4) capable of delivering data relating to various monitored parameters of the engine, means (5) of processing the data coming from the sensors (2, 3, 4), and display (6) showing the processed data relating to that parameter among the monitored engine parameters, whose current value is closest to the limiting value for the parameter. The indicator includes a testing device (12) for testing the analytical consistency between at least one of the parameters and at least one other of the parameters.
