![]() CMC Electronics’ GPS Receiver Selected By BAE Systems The quadruple-redundant electronic flight control system also has a mechanically-actuated backup system. The digital avionics system has four Honeywell multifunction cathode-ray tube displays, two full-capability HUDs (head-up displays) plus cargo systems. Cockpit of the C-17 Globemaster III Image C-17 Overhead Panel – Image C-17 cockpit accommodates pilot, co-pilot and two observer positions. A fully loaded aircraft is capable of backing up a 2% gradient slope using the directed flow thrust reversers. The aircraft can also carry out routine backing. The aircraft is capable of turning in a small radius and can complete a 180° star turn in 80ft. The landing gear can support steep-angle combat zone landings. The main gear extends straight down from its sponsons all landing gear assemblies will open by gravity in case of system failure. The nose gear retracts forward and is steerable by rudder pedals, as well as a tiller for tight ground maneuvering. The nose landing gear has two wheels, while each of the two main gear assemblies has six wheels in two rows of three. It is unclear if the entire fleet has been kitted up to ER specification. In later production, at least some C-17s were fitted with a wing center-section tank with a capacity of 36,340 liters (9,600 US gallons) of fuel, these aircraft being informally designated as “C-17 ER”. An inert-gas generation system helps reduce fuel system fires or explosions. There are six fuel tanks in the wings, with a total capacity of 102,614 liters (27,108 US gallons), and an inflight refueling socket behind the cockpit. Auxiliary power unitĪ Honeywell auxiliary power unit (APU) turbine is fitted in the front of the right main landing gear sponson to provide engine starting and ground power a “ram air turbine” will be extended from the right sponson in the case of a comprehensive power failure, to provide hydraulic system power for minimal flight control. The engine exhaust is directed onto large flaps, which extend into the exhaust stream, allowing the aircraft to fly a steep approach at a relatively low landing speed. The propulsive lift system uses engine exhaust to generate lift. The C-17 is capable of landing a full payload in less than 3,000ft. ![]() A propulsive lift system allows the C-17 to achieve safe landings on short runways.
