In flight mechanics, the pressure correction factor is a parameter used to adjust indicated airspeed readings for variations in atmospheric pressure. It compensates for the impact of changing air density with altitude, providing a corrected airspeed known as calibrated airspeed. This correction ensures more accurate airspeed measurements, critical for precise aircraft performance and navigation, especially when flying at different altitudes. The formula to calculate Pressure correction factor as follows:
Where:
- Ve is the Equivalent airspeed in m/s.
- Vc is the Calibrated airspeed in m/s.
