Embedded engine diagnostic system

摘要

An engine diagnostic system includes a plurality of sensors (4). One of the plurality of sensors includes a speed sensor generating a speed value indicative of aircraft speed. A processor (2) is coupled to the sensors and stores prior mission data and current mission data in a data memory (12) when the speed value is within a predetermined velocity range. A fault indicator (6) is provided which is visible from the exterior of the aircraft. The processor detects a presence or absence of a fault in response to the prior mission data and current mission data and activates the fault indicator in response to the presence of a fault.
