Mastering Stalls: How to Recognize, Prevent, and Recover Safely

Flight Training Central

Depending on design, airfoils used in general aviation, stall at angles of attack between 16 to 18 degrees. The power on stall simulates the takeoff and departure situations, and the power off stalls the approach and landing conditions. At the normal approach speed, lower the nose to the approach pitch attitude.

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?

There’s Something Essential in the Bank

Flying Magazine

Wing warping,” as this approach was called, was satisfactory for very slow airplanes, but faster ones required more rigidity, and by around 1908 or 1909 the idea had arisen of replacing part of the trailing edge of a wing with a hinged, controllable flap.

What Is Bernoulli’s Principle? A Simple Guide for Pilots

Pilot Institute

Airfoils use this principle, with faster airflow over the top creating lower pressure. As the airflow approaches the wing, the flow splits above and below the leading edge. Engineers use Bernoullis principle to shape airfoils to optimize the pressure difference needed for efficient lift generation.

Nemesis NXT

Plane and Pilot

The NXT was designed using computer-based computational fluid dynamics (CFD), NASA-derived airfoils, and was tested in the Lockheed wind tunnel to refine the aerodynamics. He flies downwind leg at 150 mph, final approach at 130, and touchdown at 110the NXT stalls at 90 mph. Flying the NXT is an experience.

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. That was one thing I was kind of surprised at.”
