Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

Have you ever seen an airplane with no tail and no vertical fin, but with just a sleek wing? A tailless aircraft is a fixed-wing airplane without a horizontal stabilizing surface. A tailless airplane is one where everything needed to fly, like lift, control, and stability, is built into the main wing.

Mach Number Explained: What It Is and Why Pilots Use It

Pilot Institute

Making the wing relatively flat on top with a blunter leading edge and more curvature on the bottom gives you a supercritical airfoil. Monitoring Mach Number in the Cockpit Since IAS fails to accurately estimate speed at high altitudes, pilots switch to the Mach scale to manage their speed once they’re in a high-altitude cruise.

Flight Test Files: B-47A Stratojet

Vintage Aviation News

In 1954 this photo of two swept wing airplanes was taken on the ramp of NACA High-Speed Flight Research Station. The drag chute was used on landings to help brake the airplane’s speed. The door to the cockpit area is open, showing a view of the ladder that folds down to be used by the pilots to enter and leave the area.

FAA Releases Powered-Lift Certification Guidance

Flying Magazine

Powered-lift models have characteristics of both airplanes and rotorcraft, which places the regulator in a bind when it comes to defining their airworthiness. For lift during horizontal flight, they use rigid airfoils such as wings.

The Hughes H-1 Racer: Howard Hughes’ Silver Bullet

Vintage Aviation News

However, Hughes was never one to rest on his laurels, and as he surveyed the airplanes parked in Miami, he told his chief aeronautical engineer, Glenn Odekirk, “Hell, Glenn, there isn’t a decent plane in the lot.” ” Odekirk replied, “Howard, you’ll never be satisfied until you build your own.”

What Is a Variable-Sweep Wing? How Swing Wings Work

Pilot Institute

A variable-sweep wing, also called a “swing wing,” is a type of airplane wing that can change its angle while flying. You can adjust the wings using a manual control in the cockpit. The design adds weight, complexity, and maintenance needs. Modern jets favor simpler, stealthier fixed-wing designs. What Is a Variable-Sweep Wing?
