Wingtip Vortices and Wake Turbulence

Pilot Institute

When air flows over the aircraft wing, the shape of the airfoil creates low pressure above the wing and relatively higher pressure below the wing. Pilots need to keep this behavior in mind as theyre likely to encounter these vortices while theyre on approach or during departure. How Are Wingtip Vortices Formed?

A Bristol Bulldog Biplane Fighter is Once Again in the Sky

Vintage Aviation News

” Bristol Bulldog at Tillamook Airport After a short time in the air, Storo circled around to approach Tillamook Airport setting up for landing. The tail touched down hard, but to save the landing—and the airplane—Storo put power to it and went around for another approach. It is a terrible airplane for crosswinds.

The Role of Newton’s Third Law in Aviation

Pilot Institute

They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. This is why the typical airfoil shape has a curved top and a flat bottom, especially in slower-speed general aviation aircraft. Whenever aircraft encounter crosswinds, the most noticeable impact is felt in yaw.

Return to Form

Plane and Pilot

For one thing, the F2s fuselage hangs from a completely new wing with two distinct airfoil shapes. An obvious discontinuity leads to a thinner airfoil inboard. You might ask what happens with crosswind landings when you take away rudder authority. Wings, Things Major aerodynamic tweaks have been made. In this case, nothing.

Nothing Small About It

Plane and Pilot

But it was apparent the smallest Grumman flying boat was too small and full of quirks—the cabin door won’t open if the flaps are down, for example—to justify something approaching a direct copy. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.
