The definition of AGL is given above, so look at the related information. A pilot flying an aircraft under instrument flight rules (usually in poor visibility) must rely on the aircraft`s altimeter to decide when to deploy the landing gear and prepare for landing. Therefore, the pilot needs reliable information about the altitude of the aircraft in relation to the landing zone (usually an airport). The altimeter, which is usually a barometer calibrated in units of distance instead of atmospheric pressure, can therefore be set to display the altitude of the aircraft above the ground. This is done by communicating with the airport control tower (to get the current surface pressure) and setting the altimeter to show zero on the ground of that airport. Confusion between AGL and AMSL or improper calibration of the altimeter can result in a controlled flight in the field and the crash of a fully functional aircraft under the pilot`s control.

While the use of a barometric elevation setting that provides a zero value at the bottom of the airport is an available reference for pilots, in commercial aviation it is a country-specific procedure that is not often used (it is used, for example, in Russia and other countries). Most countries (Far East, North and South America, all of Europe, Africa, Australia) use the AMSL altitude (above mean sea level) of the airport as a reference. When landing approaches, several other references are used, including AFE (above the altitude of the field), which is the altitude that refers to the highest point of the aerodrome, TDZE (height of the landing zone) or TH (height of the threshold), both of which refer to the height of the landing site of the runway, measured AMSL and AGL, respectively. In general, “altitude” refers to distance above mean sea level (MSL or AMSL), “altitude” refers to distance above a certain point (e.g., airport, runway threshold, or ground at the current location), and “altitude” describes a feature of the terrain itself in terms of distance above MSL. [2] [3] One mnemonic that can be used is: if it`s a height, you can fly there, if it`s a height, you can go there, and if it`s the altitude, a rock will fall before it hits the ground. In meteorological and climate studies, measurements or simulations often have to refer to a specific altitude or altitude, which is, of course, AGL. However, the values of geophysical variables measured at different points on the natural surface (soil) cannot be easily compared in hilly or mountainous terrain, as part of the observed variability is due to changes in surface height. For this reason, variables such as pressure or temperature are sometimes “reduced” at sea level.
In aviation, atmospheric science and broadcasting, a height above the ground (AGL[1] or HAGL) is a height measured relative to the underground surface of the ground. This contrasts with altitude above mean sea level (AMSL or HAMSL), altitude above the ellipsoid (HAE, as reported by a GPS receiver) or altitude above average terrain (AAT or HAAT, in broadcasting technology). In other words, these expressions (AGL, AMSL, EDT, AAT) indicate where the “zero level” or “reference height” – the vertical date – is located. However, from the point of view of flight safety, the most important aspect is the height of the radio tower used to support the radio antenna. In this case, AGL altitude is the only important measure for aviation authorities, who require some tall towers to have adequate aircraft color and warning lighting to avoid collisions. In general circulation models and global climate models, the state and properties of the atmosphere at a number of distinct locations and altitudes are specified or calculated. If the topography of the continents is explicitly represented, the heights of these places are determined above the simulated ground level. This is often implemented using the sigma coordinate system, which is the pressure ratio in a location (latitude, longitude, altitude) divided by the nadir pressure of that location on the ground surface (same latitude, same longitude, height AGL = 0). In broadcasting, high-altitude AGL has relatively little direct influence on the transmission range of a transmitter. Rather, HAAT (the altitude above the average terrain (in the region)) is used to determine the distance travelled by a broadcasting station (or any other type of FM transmission or higher frequency).
