 Altimetry Help    QNH Your source for: Online Aviation Instrument Simulators + E6b, CR3 and other Flight Computer Calculators

 Using the QNH (altimeter setting) Calculator Example 1: If the pressure altitude at the airport is 2530 ft and the airport's altitude is 1820 ft, what is the altimeter setting? Begin by highlighting the field that corresponds to airport altitude in ft. Enter the 1820 value. Now highlight the field that corresponds to the pressure altitude in ft. Enter the 2530 value. The remaining field is the altimeter setting. Press "Eval" and read the answer 29.16 inHg on (a). You also get a result in HPa or mbars in (b). Example 2: What is the airport's altitude if the altimeter setting is 30.14 inHg and the pressure altitude is 4520 ft?: Begin by highlighting the field that corresponds to the altimeter setting in inHg. Enter the 30.14 value. Now highlight the field that corresponds to the pressure altitude in ft. Enter the 4520 value. The remaining field is the airport altitude. Press "Eval" and read the answer 4722 ft on (a). You also get a result in meters in (b).
