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. Recovery is made by lowering the nose, simultaneously applying full power while maintaining directional control with coordinated use of aileron and rudder. The recovery procedure is the same as for all stalls.

There’s Something Essential in the Bank

Flying Magazine

Despite the early invention of the aileron, wing warping continued to be used, even on some fighters, as late as 1916. The function of an aileron, or any hinged trailing-edge surface, is commonly explained in ground school by simple analogy to, say, a door opened on a windy day. It affects the entire area ahead of the aileron as well.

Flight Test Files: Convair XF-92A Dart

Vintage Aviation News

The delta wing’s large area (425 square feet), thin airfoil cross section, low weight, and structural strength made a great combination for a supersonic aircraft. It was controlled by a conventional rudder and full-span elevons that functioned as elevators and ailerons. The XF-92A was then used to test the delta-wing concept.

Chord Line in Aviation? What It Is and Why It Is Important

Pilot Institute

Wing Control: Flaps, slats, and ailerons change the chord line, impacting lift and control. In general, the chord line is used as an easy-to-understand reference when referring to the properties of a wing or airfoil. Basically, the mean camber line is meant to indicate the midpoint between the top and bottom surfaces of the airfoil.

The Albree Pigeon-Fraser: The First American Fighter

Vintage Aviation News

The Pigeon-Fraser Model SG was powered by a single 100hp Gnme rotary engine, had a length of 24 feet with a wingspan of 37 feet, 11 inches, and its single-set of wings featured a flat-bottomed airfoil. Timson had designed nearly ten years prior.

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. When the aircraft encounters a vortex and its strong enough to induce roll, the pilot counters it by using the ailerons against the roll and tries to fly out of the wake as soon as possible.
