Harrier Jump Jet II Plus configuration) was delivered in December 2003, ending the Harrier production line. The Harrier Jump Jet, capable of taking off vertically, can only do so at less than its maximum loaded weight. In most cases, a short take off is performed, using forward speed to achieve aerodynamic lift, which uses fuel more economically than a vertical take off. On aircraft carriers, a ski-jump ramp is employed at the bow of the carrier to assist the aircraft in becoming airborne. Landings are typically performed very differently. Although a conventional landing is possible, the range of speeds at which this can
Jet airliner the 747-400. The most modern airliners are characterized by increased use of composite materials, turbofan engines with higher degree of bypass and total compression ratio, and more advanced digital avionics. Examples of the latest widebody airliners are the Airbus A380 (first flight in 2005), Boeing 787 (first flight in 2009) and Airbus A350 (first flight in 2013). These improvements allowed longer ranges and lower cost of transportation per passenger. Sukhoi Superjet 100 and Airbus A220 (formerly Bombardier CSeries) are examples of narrowbodies with similar level of technological advancements. Jet airliner A jet airliner (or jetliner, in its portmanteau form) is
