Twinjet

Twinjet

A twinjet is a jet aircraft powered by two engines. There are two common configurations of the engines; one sees either engine slung under a wing, and the other sees them mounted at the back of the fuselage. Twinjets tend to be quieter and more efficient than aircraft with either three or four engines. Many airlines use twinjets exclusively, such as US Airways, American Airlines , Delta Air Lines and Continental Airlines in the United States.

In the event of an engine failure, the remaining engine must provide enough thrust to keep the airplane in flight until land can be reached. This is the basis of ETOPS/LROPS, a set of standards twinjets traveling over water must meet.

Some twinjets include:
* Airliners: McDonnell Douglas DC-9 (Including MD-80), Boeing 717, 737, 757, 767, 777 & 787, Airbus A300, A310, A320, A330 & A350
* Fighter planes:Lockheed F22, McDonnell F2H Banshee, McDonnell Douglas F-15 Eagle, Eurofighter Typhoon, Dassault Rafale, Grumman F-14 Tomcat and McDonnell Douglas F-18 Hornet.

*Trijet
*ETOPS/LROPS
