Airplanes and Aerodynamics

To enable the pilot to make steeper approaches to a landing without increasing the airspeed.

During unaccelerated flight.

Lift equals weight and thrust equals drag.

Stalled.

Both wings are stalled.

Frost will disrupt the smooth flow of air over the wing, adversely affecting its lifting capability.

Frost spoils the smooth flow of air over the wings, thereby decreasing lifting capability.

Frost may prevent the airplane from becoming airborne at normal takeoff speed.

The result of the interference of the surface of the Earth with the airflow patterns about an airplane.

less than the length of the wingspan above the surface.

Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.
