The pitch angle of an aircraft refers to the angle at which the longitudinal axis of the aircraft deviates from the horizontal plane. It indicates whether the aircraft’s nose is pointing upwards (positive pitch) or downwards (negative pitch) relative to the horizontal. The pitch angle of an aircraft is also commonly known as the attitude […]

The angle of attack (AOA) is the angle between the chord line of an airfoil and the relative wind. It is typically measured in degrees or radians. A positive angle of attack typically generates lift, while a negative angle of attack can result in a stall or increased drag. The formula for the angle of

In flight mechanics, the Reynolds number (Re) is a dimensionless quantity used to characterize the flow of air around an aircraft. It’s defined as the ratio of inertial forces to viscous forces in the airflow. The Reynolds number is crucial in determining whether the flow around an aircraft is laminar or turbulent and affects various

The rate of turn (ROT) from the turn radius in flight mechanics refers to the angular velocity at which an aircraft changes its heading while maintaining a constant altitude and airspeed. The formula indicates that the rate of turn is inversely proportional to the turn radius. In other words, smaller turn radii result in higher rates
