Abstract

The present invention relates to a method for monitoring the integrity of an inertial measurement assembly (10) of an aircraft, the measurement assembly comprising at least one high-grade measurement unit (20); and at least two low-grade measurement units (30, 40); wherein each of the measurement units (20, 30, 40) comprises a sensor unit (22, 32, 42) and a processing unit (24, 34, 44) operatively coupled to the respective sensor unit (22, 32, 42), wherein the respective sensor units (22, 32, 42) measure accelerations and angular rates of the aircraft and provide raw data based on said measurements; wherein the respective processing units (24, 34, 44) process the raw data provided by the sensor units (22, 32, 42) and provide processed data reflecting the velocity and/or attitude of the aircraft; the method comprising: at a sensor monitoring unit (50), receiving the raw data output by each of the sensor units (22, 32, 42) and evaluating according to at least one predetermined criterion whether the raw data of each sensor unit (22, 32, 42) are consistent with one another; and at an attitude monitoring unit (52), receiving the processed data output by each of the processing units (24, 34, 44) and evaluating according to at least one predetermined criterion whether the processed data of each processing unit (24, 34, 44) are consistent with one another. The invention furthermore relates to a corresponding inertial measurement assembly (10) of an aircraft with integrated integrity monitoring and an aircraft comprising such an assembly.
