Technical Field
[0001] This utility model belongs to the field of avionics technology, and specifically relates to a stacking protection recorder. Background Technology
[0002] The flight data recording system is used to collect and record various flight and audio data on the aircraft. The existing protective recorder's various boards are directly interconnected through wires. When replacing or maintaining the boards later, it is necessary to disconnect the wires between the modules, which makes maintenance difficult and unfavorable for field maintenance. At the same time, the original equipment has limited functionality. If it is necessary to expand other functions, additional equipment is required, which cannot meet the new requirements of lightweight and miniaturized small aircraft. Utility Model Content
