## What is the meaning of MSL?

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 ).

## Do pilots use MSL or 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. Pilots use altimeters, which measure the AGL, when the aircraft is flying at relatively low heights landing at an airport.

## 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.

## 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.

## Do pilots use feet or meters?

Cloud height, visibility, runway length, and other distance measurements are often stated in meters or kilometers in those countries that use the metric system. Feet is just a “too good” natural fit for altitude, and is practically a dimensionless quantity. ATC and Pilots don’t care if it’s feet, meters, or whatzits.

## Is density altitude MSL or AGL?

There are 5 types of altitude in aviation: Absolute altitude in feet AGL ( above ground level) True altitude in feet MSL (above mean sea level ) Pressure Altitude. Density Altitude.

## 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.

## Is sea level 0 feet?

Sea level is the base for measuring elevation. Sea level elevation is defined as 0 ft. All other elevations are measured from sea level. Those places on Earth that are above sea level have positive elevations, and those places on Earth that are below sea level have negative elevations.

## What does AGL mean in aviation?

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

## What is height in aviation?

Height. It is simply the distance between the plane and the ground underneath directly influenced by the rise of terrains. For example, if you fly at an altitude of 100 feet above the ground and passed on a plateau height of 70 feet, suddenly your height above ground becomes 30 feet only.

## Are sectional charts MSL or AGL?

Sectional charts normally show both mean sea level ( MSL ) and above ground level ( AGL ) heights for towers. The top number is the height in MSL and the bottom number — in parentheses — is the height of the tower in AGL.
