# FAQ: What Does Msl Mean In Aviation?

## What is MSL vs AGL?

Above Ground Level, or AGL, describes the literal height above the ground over which you’re flying. Mean Sea Level, or MSL, is your true altitude or elevation. A plane that flies at 10,000 feet MSL and stays level registers as flying at 10,000 feet MSL — no matter the terrain changes below the pilot.

## How is MSL calculated?

For a period of about 19 years, the MSL has been continuously measured using the rise and fall of the ocean on the seacoasts. The atmospheric pressure and temperature also play a role in the continuous motion of the sea and being able to measure its level. A datum is the easiest way to calculate the MSL.

## What does the term of MSL mean?

Average height of the surface of the sea for all stages of the tide over a 19-year period. NOTE: when the abbreviation MSL is used in conjunction with a number of feet, it implies altitude above sea level (e.g., 1000 feet MSL ).

## Is airport elevation in MSL or AGL?

The Federal Aviation Administration (FAA) defines the Airport Elevation as the highest point of an airport’s usable runways and is measured in height above mean sea level. AGL is the altitude expressed in the actual number of feet measured above the ground.

## Is Oroca MSL or AGL?

Flight Planning When planning your flight remember that the MEF and OROCA are listed in msl and ceilings are in agl.

## Does altimeter show AGL or MSL?

Despite MSL being considered the “true” altitude, AGL is more commonly used in aviation. The altimeter of your drone, as well those of manned aircraft, use the AGL values when flying near an established facility or the aircraft’s takeoff point.

## What is MSL datum?

For the purpose of measuring the height of objects on land, the usual datum used is mean sea level ( MSL ). This is a tidal datum which is described as the arithmetic mean of the hourly water elevation taken over a specific 19 years cycle.

## What level is sea level?

A common and relatively straightforward mean sea – level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales.

## Why is MSL written on railway station?

With the help of the mean sea level, the train driver and the guard can measure the gradient or slope between two stations. This helps the driver and the train engineers to calculate the speed to be maintained between the stations. The elevation is also mentioned on railway bridges.

## What does Fl mean in aviation?

Flight Level ( FL ) Altitude above sea-level in 100 feet units measured according to a standard atmosphere. Strictly speaking a flight level is an indication of pressure, not of altitude.

## What does AGL mean in aviation?

ABOVE GROUND LEVEL ( AGL ): An elevation datum given in feet above ground level.
