The Altitude Correction is a factor used in aviation to adjust pressure altitude to account for variations from standard atmospheric conditions.
The formula for Altitude Correction is as follows:
- 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.
