Altitude

Hey guys I wanted to know what is the difference between altitude agl and altitude msl. Thanks

AGL is above ground level. MSL is mean sea level. Some places would be very high and say 5000ft msl, but you actually might just be 0ft agl.

Agl is above ground level. MSL is sea level. If you’re flying near mountains AGl is better because msl isn’t your actual height above ground.

Thanks guys, helped!

in my ‘bar’ at the bottom of the screen I always have AGL as well as GS as two of the details as this helps a lot in flying and avoiding things like flying into mountains and getting penalties for taxing/flying to fast!

@Joe had a great post on this in another thread that had this image.

If you’re flying over uneven terrain (like mountains) you’re AGL may be constantly changing although your MSL hasn’t changed and you are at level flight. Just a side note.

Yea, make sure when flying in Denver to have altitude agl on your status bar.
