For instance, in Australia, VMC minima outside controlled airspace are clear of cloud with 5,000 m visibility below 3,000 ft AMSL or 1,000 ft AGL (whichever is higher), and 1,000 ft vertical/1,500 m horizontal separation from cloud above these altitudes or in controlled airspace. Above 10,000 ft, 8,000 m visibility is required to maintain VMC.

In aviation, atmospheric sciences and broadcasting, a height above ground level (AGL [1] or HAGL) is a height measured with respect to the underlying ground surface.This is as opposed to height above mean sea level (AMSL or HAMSL), height above ellipsoid (HAE, as reported by a GPS receiver), or height above average terrain (AAT or HAAT, in broadcast engineering).
ASOS sensors, located at Salinas, California. Surface weather observations have traditionally been taken at airports due to safety concerns during takeoffs and landings. The ICAO defines the International Standard Atmosphere (also known as ICAO Standard Atmosphere), which is the model of the standard variation of pressure, temperature, density, and viscosity with elevation/altitude in the ...
The QNH altimeter setting is one of the data included in METAR messages. An alternative setting is QFE or SPS/STD: An alternative setting is QFE or SPS/STD: QNH - is the barometric altimeter setting that causes an altimeter to read aircraft elevation above mean sea level - altitude ( AMSL - above mean sea level) in ISA temperature conditions in ...
It relates to the packaging and handling precautions for some semiconductors. The MSL is an electronic standard for the time period in which a moisture sensitive device can be exposed to ambient room conditions (30 °C/85%RH at Level 1; 30 °C/60%RH at all other levels). Increasingly, semiconductors have been manufactured in smaller sizes.
Height above mean sea level is a measure of a location's vertical distance (height, elevation or altitude) in reference to a vertical datum based on a historic mean sea level.
Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW). In non-tidal areas, e.g. the Baltic Sea , mean sea level (MSL) is used. [ 2 ] A chart datum is a type of vertical datum and must not be confused with the horizontal datum for the chart.
