3 Terminology and units of measurement
3.1 Terminology
The membrane box is used as a sensitive element to measure the atmospheric static pressure, and the measured static pressure is converted into
An instrument that converts pressure into altitude.
Use the diaphragm as a sensitive element to measure atmospheric static pressure and total pressure, and use the changes between airspeed and atmospheric static pressure and total pressure.
An instrument that regularly converts measured static pressure and total pressure into airspeed.
3.1.3 CapsuleMachgauges
The diaphragm is used as a sensitive element to measure the atmospheric static pressure and total pressure, and the change between Mach number and atmospheric static pressure and total pressure is used.
An instrument that converts the measured static pressure and total pressure into Mach number according to the chemical law.
3.2 Unit of measurement
The measurement unit used by the altimeter is meters (m) or kilometers (km).
The unit of measurement used by the airspeed indicator is kilometers per hour (km/h).
