Airplane : Boeing C-17 Globemaster III

16 mai 2017

St. Maartener’s were in for quite a sight on Sunday when the huge Boeing C-17 Globemaster III, a large military transport aircraft, made an approach to Princess Juliana runway four times on Sunday afternoon.

With four approaches and four takeoffs and no actually stopping to drop off or pick up anyone or anything the plane finally left – a little excitement and a big thrill on Mother’s day for all who saw her.

The military airlift aircraft was developed for the United States Air Force from the 1980s to the early 1990s, the aircraft is a high-wing, four-engine, T-tailed military transport vehicle capable of carrying payloads up to 169,000lb .
It has an international range and the ability to land on small airfields. A fully integrated electronic cockpit and advanced cargo system allows a crew of three (the pilot, co-pilot and loadmaster) to operate all systems on any type of mission.
Since it entered service in January 1995, 218 aircraft have been delivered to the US Air Force.
A propulsive lift system allows the C-17 to achieve safe landings on short runways. The C-17 is capable of landing a full payload in less than 3,000ft. The propulsive lift system uses engine exhaust to generate lift.
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 aircraft is capable of turning in a small radius and can complete a 180* star turn in 80ft. The aircraft can also carry out routine backing. A fully loaded aircraft is capable of backing up a 2% gradient slope using the directed flow thrust reversers.
The C-17 cockpit accommodates pilot, co-pilot and two observer positions. The digital avionics system has four Honeywell multifunction cathode-ray tube displays, two full-capability HUDs (head-up displays) plus cargo systems.
The quadruple-redundant electronic flight control system also has a mechanically-actuated backup system.
There are two Lockheed Martin central processing computers, one Hamilton Sundstrand data management computer and two Honeywell air data computers.
The design of the cargo compartment allows the C-17 to carry a wide range of vehicles, palleted cargo, paratroops, air-drop loads and aeromedical evacuees.
