How much time can a tailwind save?

A 3,000-mile flight flown at 500 knots takes six hours in no wind. With a 100-knot tailwind, the flight takes five hours, and a 100-knot headwind in the opposite direction would balloon the flight time to 7.5 hours. The roundtrip with no wind: 12 hours. The roundtrip with a tailwind/headwind: 12.5 hours.

In the cruise phase, tailwinds make flights more efficient by reducing fuel burn (due to the reduced drag).

A: Airplanes only know their speed in relation to the air around them. If there is a 200 mph tail wind, the speed of the airplane across the ground would be over 750 mph.

AMARG: The World's Biggest Boneyard. On average, an aircraft is operable for about 30 years before it has to be retired. A Boeing 747 can endure about 35,000 pressurization cycles and flights—roughly 135,000 to 165,000 flight hours—before metal fatigue sets in. 747s are retired after approximately 27 years of service.

Operate in accordance with Manufacturer's Limitations: Aircraft manufacturers publish a tailwind component limit for both takeoff and landing in the AFM. In most cases, it is in the order of 10 knots but may be as high as 15 knots.

Because headwind increases the lift, pilots prefer to land and take off in headwind. Tailwind is wind blowing from behind the aircraft. It reduces the lift and aircraft generally avoid taking off or landing in tailwind.

Even a bit of tailwind can be a hazard. Tailwind conditions can have adverse effects on aircraft performance and handling qualities in the critical flight phases of takeoff, approach and landing. Tailwind, for instance, increases the required runway length to land on or takeoff from.

Built in 1967 to produce the mammoth jet, it remains the world's largest manufacturing plant according to Boeing. But after five decades, customer demand for the 747 eroded as Boeing and Airbus (AIR.PA) developed more fuel efficient two-engine widebody planes.
