Pressure altitude is a term used in aviation to describe the altitude of an aircraft based on atmospheric pressure. It is a key parameter for navigation and flight planning.
The formula for pressure altitude is as follows:
- Pressure Altitude (PA) is the calculated altitude based on atmospheric pressure, often measured in feet (ft) or meters (m).
- Standard Pressure Altitude is the altitude at which the current atmospheric pressure matches the standard pressure for that altitude. It is typically provided in aviation charts or tables.
- Altitude Correction is a correction factor applied to account for variations in atmospheric pressure from standard conditions.
