The Lockheed C-5 Galaxy is a large military transport aircraft designed and built by Lockheed, and now maintained and upgraded by its successor, Lockheed Martin.It provides the United States Air Force (USAF) with a heavy intercontinental-range strategic airlift capability, one that can carry outsized and oversized loads, including all air-certifiable cargo.
The light characteristics of all light units are identical. In good visibility conditions the guidance information can be used at ranges up to 5 miles (8.0 km) by day and night. At night the light bars can be seen at ranges of at least 20 miles (32 km). PAPI systems are readily available from airfield lighting manufacturers worldwide.
Landing lights are usually of very high intensity, because of the considerable distance that may separate an aircraft from terrain or obstacles. The landing lights of large aircraft can easily be seen by other aircraft over 100 miles away. Key considerations of landing light design include intensity, reliability, weight, and power consumption.
At 222 feet across, almost 300 feet in length, and 65 feet above the ground, Lockheed Martin's C-5 Galaxy is the largest transport aircraft in the US Air Force.. With a cargo hull 121 feet long ...
Wave-off lights – red flashing lamps which, when lit, indicate that the pilot must add full power and go around – a mandatory command. When the wave-off lights are lit, all other lamps are extinguished. The wave-off lights are operated manually by the LSO. Some (particularly later) optical landing systems include additional lamps:
The visual approach slope indicator (VASI) is a system of lights on the side of an airport runway threshold that provides visual descent guidance information during final approach. These lights may be visible from up to 8 kilometres (5.0 mi) during the day and up to 32 kilometres (20 mi) or more at night.
The landing gear represents 2.5 to 5% of the maximum takeoff weight (MTOW) and 1.5 to 1.75% of the aircraft cost, but 20% of the airframe direct maintenance cost. A suitably-designed wheel can support 30 t (66,000 lb), tolerate a ground speed of 300 km/h and roll a distance of 500,000 km (310,000 mi) ; it has a 20,000 hours time between overhaul and a 60,000 hours or 20 year life time.
The sea ice runway was capable of handling wheeled aircraft, which have included to date: Lockheed C-5 Galaxy, Lockheed C-141 Starlifter, Boeing C-17 Globemaster III, Lockheed C-130 Hercules and Lockheed P-3 Orion. In the summer season of 2009/2010 the RNZAF trialed a modified Boeing 757 operationally. The intention was to use the Boeing 757 ...
