# FAQ: What Does Msl Stand For 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 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 ).

## What is MSL airspace?

MSL stands for Mean Sea Level or more accurately, Above Mean Sea Level. Altitude values expressed in MSL are measured against the sea level, which makes it a constant value regardless of the terrain you’re flying over.

## 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.

## Are approach plates in MSL or AGL?

Traffic pattern altitudes are usually 800 or 1,000′ AGL but expressed as MSL. It’s good to know for planning purposes how high above the ground you will be, but (in the US at least) you use MSL on your altimeter to fly the pattern. Approach charts (US TPPs) do show AGL below the MSL values.

## 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 is MSL on cell phone?

MSL is the acronym for Master Subsidy Lock.

## What does MSL stand for in sports?

MSL means Major Soccer League. Abbreviation is mostly used in categories: Football Soccer Sports League Sport. Rating: 6.

## What is an MSL manager?

The Medical Science Liaison ( MSL ) is a specialized role within the pharmaceutical, biotechnology, medical device, and related health-care fields. Some typical tasks that an MSL may undertake include: Responding to requests for information. Providing training to sales and marketing teams.

## What airspace is above FL600?

Airspace at any altitude over FL600 (60,000 MSL) (the ceiling of Class A airspace ) is designated Class E airspace. The U.S. does not use ICAO Class F.

## Is Class B airspace AGL or MSL?

Class B airspace is generally airspace from the surface to 10,000 feet MSL surrounding the nation’s busiest airports in terms of airport operations or passenger enplanements.

## 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.
