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

Pilot Institute

Why do jet pilots talk about speed in terms of Mach number? Why don’t they use Indicated Airspeed just like the pilots who fly slower aircraft? Pilots switch to Mach number at high altitudes to avoid inaccuracies in IAS due to compressibility effects. And why should pilots be wary of Mach 1? Here’s why. Here’s why.

Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

A tailless aircraft is a fixed-wing airplane without a horizontal stabilizing surface. With this type of aircraft, the functions of longitudinal stability and control are incorporated into the main wing. A tailless airplane is one where everything needed to fly, like lift, control, and stability, is built into the main wing.

Flight Test Files: The Douglas D-558-2 Skyrocket – Chasing Mach 2

Vintage Aviation News

These stories shine a light on the aircraft and test pilots that pushed the limits of aeronautical knowledge, many of them flying out of the legendary Dryden Flight Research Center (now Armstrong Flight Research Center) at Edwards Air Force Base, California. Research pilot John McKay flew it once in this form on September 17, 1956.

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. When the airplane is stabilized in the approach attitude and speed, begin to smoothly and slowly bring the nose up to an attitude which will cause a stall. As the airspeed slows into the white arc, extend the wing flaps.

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. The pilot also reported that the aircraft was sluggish and underpowered. feet high at the tip of the vertical stabilizer. feet long, had a 31.3-foot

Flight Test Files: Grumman F-14 Tomcat

Vintage Aviation News

The F-14s unique roll control setup, which relies on differential horizontal stabilizers and spoilers rather than traditional ailerons, provided effective control at various speeds but also introduced side forces that could contribute to spin entry. This configuration, while beneficial for carrier takeoffs, added complexity to spin behavior.

The Role of Newton’s Third Law in Aviation

Pilot Institute

Newton’s Third Law helps pilots and engineers improve flight safety and aircraft performance. They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. So, pilots must find the sweet spot: enough angle to generate strong lift but not so steep that airflow breaks away.
