Notes:

This is the Tornado cockpit Data Entry Unit which has a drawer for the TDM (C0231, C0559) data cartridge and provides the interface to the aircraft systems. The drawer for the TDM has 12 round glass-windowed photo-transistors, interspersed with photo-diodes to form a 12-bit electro-optical data interface that is more rugged than normal mechanical electrical connectors. This interface structure can be seen more clearly on the TDM.
This unit is missing its door/cartridge latch.

Mission planning was once carried out with the aid of paper maps but modern military aircraft have sophisticated navigation and attack systems and film or digital map displays. An aircraft’s mission is planned on the ground at a workstation  now called  an Advanced Mission Planning Aid (AMPA).
Currently Tornado missions are planned manually, and a cassette preparation ground station (CPGS) is used to load the plan on to a cassette which is taken to the aircraft and downloaded into the mission computer via the voice recorder. While the plan is being prepared the aircraft waits, armed and ready to go.
Apart from the route and waypoints information on threats, Radio/Nav settings, Weapons settings, terrain and flight profile are just some of the information a pilot might need for a successful mission.
Although it cannot be verified at present it is likely that these units were made by Powerplant Systems Division.
