- pressure altitude
- Definição1
- The altitude in standard atmosphere at which the pressure is the same as the existing pressure. Because a pneumatic altimeter operates solely on pressure, pressure altitude is the uncorrected altitude indicated by an altimeter when its barometric scale is adjusted to standard sea-level pressure of 29.92 inches of mercury, or 1013.2 millibars.
