Operation
The Harrier Jump Jet, capable of taking off vertically, can only do so at less than its maximum weight. In most cases the aircraft does a short take off where it gains forward speed and thus aerodynamic lift, saving fuel.
On aircraft carriers a ramp is frequently employed at the end of the carrier which allows the aircraft to accelerate along the carrier and then use a lower amount of fuel to take to the air.
Landings are also typically performed very differently. Although a conventional landing is possible, the range of speeds that this can be done over is narrow (due to relatively vulnerable outrigger undercarriage). Operationally the aircraft therefore usually does a near vertical landing with some forward speed.

Famous quotes containing the word operation:
“You may read any quantity of books, and you may almost as ignorant as you were at starting, if you don’t have, at the back of your minds, the change for words in definite images which can only be acquired through the operation of your observing faculties on the phenomena of nature.”
—Thomas Henry Huxley (1825–95)
“It is critical vision alone which can mitigate the unimpeded operation of the automatic.”
—Marshall McLuhan (1911–1980)
“It requires a surgical operation to get a joke well into a Scotch understanding. The only idea of wit, or rather that inferior variety of the electric talent which prevails occasionally in the North, and which, under the name of “Wut,” is so infinitely distressing to people of good taste, is laughing immoderately at stated intervals.”
—Sydney Smith (1771–1845)
