Capturing and retrieving data from aircraft (A/C) for the sake of flight test recording, maintenance and crash recording or mission recording& analysis are crucial for fault diagnoses and pilots training. Acquired data from A/C are sorted into two categories; first one is analog/discrete data from analog systems, while the second concerns the MIL-STD 1553 serial data of all its connected remote terminals. UMA2000 is a stateof-art Flight Data Recorder (FDR) was used as a programmable Data Acquisition System for acquiring analog, digital signals and MIL-STD 1553 data acquisition channels, as a Bus Monitor to gather information of flight mission from several systems on the A/C. This paper introduces a way of interfacing UMA2000 on the aircraft platform, gathering, decompressing, decoding, analyzing and converting data to engineering units for retrieving the mission information about the status of the engine, avionics, mission computers ….etc.
