WebAug 18, 2024 · Ground effect only begins to show up when you're within one wingspan of the ground. But, it really reduces your drag when you're within 20% of your wingspan to the ground. At that height, your wing only generates 60% of its normal induced drag. Share Improve this answer Follow answered Aug 17, 2024 at 20:04 Farhan ♦ 29.3k 14 108 182 For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface. Reduced drag when in ground effect during takeoff can cause the aircraft to "float" while below the recommended climb speed. The pilot can then fly just above the runway while the aircraft accelerates in ground effect until a safe climb speed is reached. fishing rockaway beach oregon

It all happens within one wingspan or less of the ground. So the next time you find yourself floating down the runway, go-around, and try another landing at a little slower speed. …

Ground Effect is the name given to the positive influence on the lifting characteristics of the horizontal surfaces of an aircraft wing when it is close to the ground. This effect is a consequence of the distortion of the airflow below such surfaces attributable to the proximity of the ground. It applies to … See more The increase in Liftlift created by Ground Effect comes primarily from a reduction in the amount of induced draggenerated which improves the lift/drag ratio. In most circumstances, this … See more In ground effect, the angle of attack required before a wing stalls, for a given amount of lift, is reduced.
