Amongst the key avionics features of the aircraft are the EUROGRID battlefield management and map display systems, integrated communications (HF/VHF/FM radio and satellite) and data transfer links, a high-authority digital automatic flight control system, and redundant MIL 1553 data buses. Two redundant mission computers control the weapons, sensors, and targeting functions. The Tiger's navigational suite includes GPS, dual redundant inertial referencing, Doppler radar, separated air data units, radio altimeter and distributed air speed sensors. A dedicated nose-mounted forward-looking infrared (FLIR) sensor is used by the pilot for night time flying.
