While use of a standardised pressure setting facilitates separation of aircraft from each other, it does not provide the aircraft's actual height above ground. At low altitudes, the altimeter is commonly set to show the altitude above sea level, which can be directly compared to the known elevation of the terrain. The pressure setting to achieve this varies with weather conditions. It is called QNH ("barometric pressure adjusted to sea level"), or "altimeter setting", and the current l… WebMar 6, 2024 · Let's say that an aircraft is in an area where the QNH is really 1013, and is at an altitude of 7500'.
