Basic Airplane Aerodynamics

A basic overview of the forces associated with straight and level flight, climbs, descents, and turns.


4 FORCES OF FLIGHT

Lift, Weight, Thrust and Drag

FORCES IN CLIMBS AND DESCENTS

AERODYNAMICS OF A TURN

COORDINATED AND UNCOORDINATED TURNS

SKIDDING TURN

 Forces in a Skidding Turn

In a skidding turn, the CF is greater than the HCL. This is because the rate of turn is too great for the angle of bank. The aircraft is yawed to the inside of the turning flight path in a skidding turn.

A skidding turn can be corrected by reducing rudder in the direction of the turn, and/or increasing the bank angle.
