The components of aerodynamic forces and moments are written as dimensionless coefficients called aerodynamic coefficients. The aerodynamic pressure is defined by a certain equation. The drag of a profile results from the compressive forces in the axis of the aircraft. However, it can be broken down into three distinct parts: form drag; wake drag; and induced drag. The form drag is related to the shape of the profile. The wake drag is related to the detachment of the air streams at the rear of the profile. The induced drag is related to the pressure differences between the undersurface and the upper surfaces of the wing. The lateral lift force is positive when it is directed to the right of the aircraft. The most commonly used aerodynamic derivatives are those relating to the angle of attack and sideslip, rudder deflection and the pitch, roll and yaw speeds.
