Electronics hardware of A400M military transportation aircraft will be designed by EADS company for eight countries including Turkey. EADS company will use DTM (Data Transfer Medium), which designed by TÜBİTAK Bilgem, for holding and transferring encrypted data between DAC (Defensive Aimed Computer) and PFMSE (Pre-Flight Messaging Service) Figure 1.

DTM will ensure secure communication of A400M with other peripherals. The consortium where Turkey is participating will produce A400M expected to be theFuture International Military Airlifter (FIMA). DTM consists of NATO approved Secure Flash Memory (SIR) and IA (interface Adapter). DTM send and receive confidential flight data to/from  DAC (Defensive Aimed Computer) via Ethernet. DTM can securely store saved flight reports on SIR and flight reports can be installed to PFMSE via USB port of SIR. Figure 2.
