( Transition Altitude (TA) is a specified altitude above mean sea level (MSL). When operating at or below TA, altimeter setting is set to QNH, and aircraft altimeters show the altitude above mean sea level.) (2)过渡高(Transition Height,TH):过渡高是一个特定的场面气压高。在该高及其以下,...
Mean Sea Level, or MSL, is the altitude calculated by the atmospheric pressure above sea level and is much more important when flying at higher altitudes. When we say Mean Sea Level (MSL), it is a calculation that is hard to make as the gravity field of the earth controls the tides, ...
84as the global coordinate system, and with it is the WGS84 ellipsoid. HAE, or Height Above Ellipsoid, or "elevation above surface of ellipsoid", is commonly the form of altitude a GPS receiver returns. It differs fromAGL(height above ground level) and MSL (height above mean sea level)....
Mean Sea Level, or MSL, is your true altitude or elevation. It’s the average height above standard sea level where the atmospheric pressure is measured in order to calibrate altitude. On a Sectional Chart, all of the numbers you see that denote altitudes are denoted in MSL, unless they a...

Altitude Measurement: In aviation, kilopascals calculate atmospheric pressure at various altitudes, contributing to accurate altimeter readings. Pilots rely on these readings to determine aircraft altitude above mean sea level (MSL) and safely navigate changing atmospheric conditions. ...

In a way, geoid is the opposite of that theoretical ellipsoid. It’s a hyperlocal survey of height measurements and a bunch of other factors, including geographical formations, the Earth’s gravity, and mean sea level (MSL), all of which are used to formulate height measurements for every ...

QNH is the QFE at an airfield, reduced to MSL (Mean Sea Level) RPS (Regional Pressure Setting) is the lowest forcast QNH for the next hour in a particular ASR (Altimeter Setting Region) On top of that, when operating above 3000', the SPS (Standard Pressure Setting) is used - a world...
