Twinjet

From Wikipedia, the free encyclopedia

A twinjet is an aircraft powered by two jet engines. Twinjets tend to be quieter and more efficient than aircraft with more engines. Many airlines use twinjets exclusively (for example US Airways, American Airlines and Delta Air Lines in USA) . However, in the even of an engine failure, the remaining engine must provide enough thrust to keep the airplane in flight for the remainder of its journey (say, over the Atlantic), requiring large twinjets to have notably large engines (for example, those of the 777).

Some twinjets include:

• Airliners: McDonnell Douglas DC-9, Boeing 717, 737, 757, 767, 777 & 787, Airbus A300, A310, A320, A330 & A350
• Fighter planes: Tupolev Tu-124, McDonnell F2H Banshee
