Flying A Holding Pattern
Many aircraft have a specific holding speed published by the manufacturer; this is a lower speed at which the aircraft uses less fuel per hour than normal cruise speeds. A typical holding speed for transport category aircraft is 210 to 265 knots (491 km/h). Holding speeds are a function of aircraft weight at the point of holding. If possible, a holding pattern is flown with flaps and landing gear up to save fuel.
Entry procedures and accurate flying of the holding procedure are essential parts of IFR pilot training, and will always be tested on examination flights.
Modern autopilots, coupled with flight management systems, can enter and fly holding patterns automatically.

Famous quotes containing the words flying, holding and/or pattern:
“A word carries far—very far—deals destruction through time as the bullets go flying through space.”
—Joseph Conrad (1857–1924)
“It was a close place. I took it up, and held it in my hand. I was trembling, because I’d got to decide, forever, betwixt two things, and I knowed it. I studied a minute, sort of holding my breath, and then says to myself: “All right, then, I’ll go to hell”—and tore it up.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“It was her stern necessity: all things
Are of one pattern made; bird, beast, and flower,
Deceive us, seeming to be many things,
And are but one. Beheld far off, they differ
As God and devil; bring them to the mind,
They dull its edge with their monotony.”
—Ralph Waldo Emerson (1803–1882)
