The sideslip angle () is the angle formed between the aircraft’s longitudinal axis and the relative wind, indicating the degree of lateral deviation from coordinated flight. The sideslip angle is crucial for controlling aerodynamic forces during maneuvers like slips and skids. Pilots rely on this information to maintain coordinated flight, especially in situations where wind or other factors can deviate the aircraft from its intended path. The formula to calculate sideslip angle as follows:
Where:
- is the sideslip angle,
- is the sideways or lateral component of the aircraft’s velocity,
- is the true airspeed of the aircraft.
