The “Correction Factor” in the Altitude Correction formula is a unit conversion factor used to ensure that the result is in the desired units, such as feet or meters, depending on the units used for pressure altitude and atmospheric pressure. Its purpose is to make the correction in the appropriate units to match the altitude measurement system’s requirements. The Correction Factor doesn’t have a fixed value but depends on the units involved.
- Altitude Correction is the correction applied to the pressure altitude.
- Current Atmospheric Pressure is the actual atmospheric pressure at the aircraft’s location, typically provided in inches of Mercury (inHg) or millibars (mb).
- Standard Atmospheric Pressure is the standard pressure at the reference altitude, usually 29.92 inHg (1013.25 mb) at sea level.
- Correction Factor is a unit conversion factor to ensure that the result is in feet or meters, depending on the units used for pressure altitude.
