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
Power tower (power take-off) Power tower (power take-off) A power tower is a type of mechanical power take-off (or pto) which resides on an auxiliary transmission. It is mounted to the top of an auxiliary transmission (also known as a brownie or joey box) and its vertical housing has earned it the name power tower. Unlike traditional transmission or engine mounted power take-offs the power tower can provide the engine's full rated power output. It is commonly used to drive large winches or hydraulic pumps. Unlike the power take-off of an agricultural tractor, the attachment of any device to the power tower is usually
