static air temperature การใช้

• In order to compute TAS the air data computer must convert total air temperature to static air temperature.
• Combining the above with the expression for Mach number gives an expression for TAS as a function of impact pressure, static pressure and static air temperature ( valid for subsonic flow ):
• In simple aircraft, without an air data computer or Machmeter, true airspeed can be calculated as a function of calibrated airspeed and local air density ( or static air temperature and pressure altitude which determine density ).
