How much does a tailwind increase landing distance?

Tailwinds And Landing Distance Most GA aircraft performance charts give you the same guidance: for operation with tailwinds up to 10 knots, increase distances by 10% for each 2 knots. That means if you're landing with a 10 knot tailwind, your landing distance increases by 50%.

4) Increased Landing Distance The same goes for landing. For each 2 knots of tailwind in a C172S, add an additional 10% to your landing distance.

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.

Other special cases include a tailwind, where the plane and wind are acting in the same direction. As you may suspect, the speed of the aircraft increases when there is a tailwind and decreases when there is a headwind.

In the landing case, tailwinds may also result in higher number of go arounds due to the increased probability for an unstable approach. This increases both pilots' and controllers' workload. Additionally, landing aircraft would be likely to remain longer on the runway and vacate via later-than-normal taxiways.

Maximum tailwind for Landing – BLY & BLZ = 15 knots, Others 10 knots. For landing with a tailwind greater than 10 knots, use FLAPS FULL only. Maximum tailwind for Automatic Landing and Rollout = 10 knots. Maximum wind for passenger door operation is 65 kt.

There's no doubt that while you can land with a tailwind, it increases your risk of things going wrong. But at the same time, most GA airplanes have performance charts that let you calculate takeoffs and landings with up to 10 knots of tailwind.

Runway slope (gradient) has a direct effect on landing distance. For example, a 1 percent downhill slope increases landing distance by 10 percent (factor of 1.1). However, this effect is accounted for in performance computations only if the runway downhill slope exceeds 2 percent.

The Boeing 747 Jumbo Jet reached a top speed of 825 miles per hour which was boosted by a strong jet-stream and tailwind of over 200 miles per hour. Aircraft that cross the Atlantic between North America and Europe flying eastbound are usually boosted by a tailwind that can shave several hours off their flight time.

Many airplanes have limitations on the amount of crosswind that is allowed for takeoff and landing. In the case of some airliners, it's around 40kts or about 45mph or 21 Mps. A 15 mph tailwind is good. A 15 mph headwind is not so good, but is usually no big deal.
