Abstract

The present invention relates to a platform and method for testing aircraft message trigger logics. Apparatus for testing message trigger logics of aircraft comprises: DFDAU (Digital Flight Data Acquisition Unit), which is adapted to receive message trigger logics to be tested; an input interface, which is adapted to receive data of aircraft condition; and a simulation signal generator, which is adapted to generate simulation signals according to the data of aircraft condition; wherein, the DFDAU is adapted to receive the simulation signals, and generate messages according to the message trigger logics to be tested.

Description

technical field [0001] The invention relates to an aircraft test device and a test method, in particular to a test platform and a test method for aircraft message trigger logic. Background technique [0002] In order to monitor and analyze the status of the aircraft, a large number of sensors are installed on the aircraft. These sensors detect and collect a large amount of aircraft status data such as the acceleration, airspeed, altitude, wing configuration, external temperature, cabin temperature and pressure, and engine performance of the aircraft. The core component for collecting and processing aircraft status data on the aircraft is the digital aircraft status data acquisition component DFDAU (Digital Flight Data Acquisition Unit). The aircraft status data collected by all sensors and transmitted by related equipment are transmitted to the aircraft DFDAU. [0003] DFDAU is an integrated airborne data acquisition and processing system. DFDAU includes a data acquisitio...
