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

Pilot Institute

Center of Gravity: Used to calculate and balance the aircraft’s center of gravity. In general, the chord line is used as an easy-to-understand reference when referring to the properties of a wing or airfoil. Where its pivot point is, is called the center of gravity. It goes something like this.

The No Longer Invisible Angle of Attack: AOA Indicators

Learn to Fly

This happens regardless of weight, bank angle, temperature, density altitude, or center of gravity. An angle of attack (AOA) indicator can determine the aerodynamic health of the airfoil (wing). An airplane will, however, always stall at the same angle of attack, called the critical angle of attack.

The Hazards of Aircraft Icing: Explained

Pilot Institute

Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Ice build-up on the airframe changes the airflow pattern around these airfoils. Additional Dangers of Ice Accumulation Icing also makes your aircraft heavier and can even change the position of the center of gravity.

Nothing Small About It

Plane and Pilot

The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance. This is a Riblett-airfoil airplane with a slow stall speed (we got it down to 42 knots IAS and it didn’t stall) and a cruise speed of 120 knots.
