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. Lift, drag, and handling correlate well with IAS in the lower atmosphere.

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

Pilot Institute

Many explanations on websites, videos, and even some textbooks oversimplify or misrepresent the true mechanics of lift. In reality, lift generation involves both Bernoullis principle and Newtons third law working together. Read on to understand Bernoullis principle and how it relates to lift the right way.

5 Most Common Aircraft Flap Types (Explained by a CFI)

Northstar VFR

Novak, CFI As a student pilot, you've probably already heard your instructor talk about using flaps during takeoff, landing, and sometimes even during slow flight practice. When deployed, they increase the wings lift and drag, allowing the airplane to fly safely at slower speeds. By Jillian C. How Do Flaps Work?

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. The Difference Between a Chord Line and a Camber Line The chord line is a straight line that crosses the leading and trailing edges of the airfoil. The mean camber line is drawn halfway between the upper and lower surfaces.

Tailless Aircraft: How Airplanes Fly Without a Tail

Pilot Institute

A tailless airplane is one where everything needed to fly, like lift, control, and stability, is built into the main wing. In level flight, the aircraft is adjusted so that the wingtips dont add lift. Upward Deflection : Raising both elevons decreases the camber of the wing. Lift is reduced, and the nose pitches downward.

Everything You Need To Know About Ailerons

Pilot Institute

Have you ever wondered how pilots keep control at high speeds, during stalls, or even when systems fail? Key Takeaways Ailerons control the aircrafts roll by adjusting lift on each wing. The pilot is able to control the aircrafts roll by turning the control yoke or sidestick in the cockpit. Why does this increase the lift?

The Most Misunderstood Aerodynamic Concepts

Flight Training Central

I have heard from a couple of different pilot examiner friends that there are a number of basic aerodynamic concepts that are often misunderstood by pilot applicants. At the private pilot level, this is disappointing, but may be understandable. This lower pressure on the top of the wing is a part of the lift production.
