The Boeing 777-100 trijet concept was proposed in 1978 to compete with other trijets of the time. In the early 1970s, the Boeing 747, McDonnell Douglas DC-10, and the Lockheed L-1011 TriStar became the first generation of wide-body passenger airliners to enter service. [7]
Pilots landing a Boeing 777. In aviation, the sterile flight deck rule or sterile cockpit rule is a procedural requirement that during critical phases of flight (normally below 10,000 ft or 3,000 m), only activities required for the safe operation of the aircraft may be carried out by the flight crew, and all non-essential activities in the cockpit are forbidden.
Manufacturers often underestimate the cost of the D check. Boeing underestimates the cost for four of its aircraft, and the expectation is that it has underestimated it for the B787-9 which in 2018 had not been in service for long enough to have been put through a D check. [15] All amounts in millions of United States dollars, as of 2018. [15]
ETOPS-180 was only possible after one year of trouble-free 120-minute ETOPS experience. In 1990 Boeing convinced the FAA that it could deliver an airliner with ETOPS-180 on its entry into service. This process was called Early ETOPS. The Boeing 777 was the first aircraft to be introduced with an ETOPS rating of 180 minutes.
The most well-known is the system of normal, alternate, direct laws and mechanical alternate control laws of the Airbus A320-A380. [3] The other is Boeing's fly-by-wire system, used in the Boeing 777, Boeing 787 Dreamliner and Boeing 747-8. [4] [6]
The aircraft manufacturer-designated checklists are always included in a QRH, and often the airline company or operator will include its own procedures. Therefore, there is no single universal QRH and they may differ widely in contents, but in practice, individual versions of it are referred to as the Quick Reference Handbook. [ 3 ]
A pilot of a DC-10 consulting his checklist. In aviation, a preflight checklist is a list of tasks that should be performed by pilots and aircrew prior to takeoff. Its purpose is to improve flight safety by ensuring that no important tasks are forgotten. Failure to correctly conduct a preflight check using a checklist is a major contributing ...
B-HNL, originally registered as N7771, at Geneva Airport on 9 September 1995. The Boeing 777 is the world's largest twin-engine jet and the first of two Boeing aircraft to feature fly-by-wire flight controls, followed by the Boeing 787 Dreamliner.
