Subsonic Relationships between Pressure Altitude, Calibrated Airspeed, and Mach Number.

摘要

This handbook derives equations for pressure altitude, calibrated airspeed, and Mach number valid for subsonic Mach numbers in the troposphere and the stratosphere using the 1976 U.S. standard atmosphere. Equations are also developed for equivalent airspeed, true airspeed, local speed of sound, and incompressible dynamic pressure. Numerical examples are presented solving for pressure altitude, calibrated airspeed, or Mach number using the other two parameters.
