HAA

Height Above Airport 
The height of the Minimum Descent Altitude (MDA) above the published airport elevation. This is published in conjunction with circling minimums.

HAT

Height Above Touchdown
The height of the Decision Height (DH) or Minimum Descent Altitude (MDA) above the highest runway elevation in the touchdown zone of the runway. HAT is published on instrument approach charts in conjunction with all straight-in minimums.

 

AFE 

Above Field Elevation

Above Field elevation is the height measured above  the highest point on the usable runway which is depicted on our charts.

AGL 

Above Ground Level

Above Ground Level (AGL) is the altitude expressed in feet measured above the ground.

 

MSL

Mean Sea Level
