Figure 7-5 Mean Sea Level Decision Height

Touchdown Zone Elevation (TDZE) - The highest elevation in the first 3000 feet of the

landing surface of a particular runway.

Airport Elevation/Field Elevation - The highest point of an airport's usable runways measured

in feet from Mean Sea Level.

Height Above Touchdown (HAT) - This is an indication of your height above the ground

(AGL) when you reach MDA or DH for all straight-in approaches, however, it is not measured

from the ground below your aircraft. It is the height of the MDA or DH above the

TOUCHDOWN ZONE. The TDZE will always be shown in the Airport Sketch adjacent to the

approach end of the runway to which you are executing the straight-in approach procedure

(Figure 7-6).

Figure 7-6 Airport Elevation

Height Above Airport (HAA) - This is the height of the MDA of the published airport elevation

expressed in feet AGL. This is published only in conjunction with circling minima. Again, this

is not measure from the ground below your aircraft. The AIRPORT ELEVATION is shown in a

separate box in the Airport Sketch (Figure 7-6).

NOTE

OPNAVINST 3710.7 sets absolute minima for single piloted

aircraft at 200 feet ceiling/HAT and 1/2 mile visibility/2400 feet

RVR, or published minima, whichever is higher. All Training

Command aircraft are considered to be single-piloted.
