Key elements of the full upgrade package include a Northrop Grumman APN-241 terrain following/terrain avoidance system; a terrain awareness and warning system; and enhanced and synthetic vision systems (SVS). This combination, along with real-time reference to a digital terrain elevation database, enables accurate low-level flight in any condition and regardless of terrain or the presence of man-made obstacles, says Gil Russo, a senior director at Elbit's aerospace division.
The SVS, meanwhile, shows a 3-D synthetic image of the external environment on a flight display.
Elbit was recently awarded a contract by the Israeli defence ministry to upgrade the Israeli air force's C-130H transports. The modernisation project will extend the operational life of the aircraft and significantly improve their operational capability, particularly during precision flying, low-level night flight and operations in adverse weather conditions.
The effort will replace obsolete analogue cockpit systems, which have become unreliable and costly to maintain after four decades of intensive service.
