Powered-lift: Heavier-than-air aircraft capable of vertical takeoff, vertical landing, and low speed flight that depends principally on engine-driven lift devices or engine thrust for lift during these flight regimes and on nonrotating airfoil(s) for lift during horizontal flight.

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.

This principle is fundamental in generating lift, thrust, and maneuverability, allowing aircraft to fly. Thrust (how it moves forward). They are designed with a special shape called an airfoil, which encourages passing air to turn and deflect downward. That force is called thrust. Wings do just that.

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.
