Mission planning was 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 and a data loading device, a non-volatile memory cartridge, is employed to download the mission information from the mission planning workstation and transfer it to the aircraft systems. 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.
ODMI0230: This is the Tornado cockpit Data Entry Unit which has a drawer for the TDM (ODMI0231, ODMI0559) 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.
