Airport Diagram -
a. Scope - Airport diagrams are specifically designed to assist in
Oceana NAS
the movement of ground traffic at locations with complex
runway/taxiway configurations and to provide information for
updating computer-based navigation systems (i.e., INS, GPS)
aboard aircraft. Airport diagrams are not intended to be used
for approach and landing or departure operations.
b. Runway dimensions, elevations, and gradient (if greater than
0.3 degrees up or down)
c.
Airport diagram scales are variable
d. Runway heading to the nearest tenth of a degree
e. Dimension of runway overruns
f.
Runway identification number
g. Location of arresting gear, barriers, and displaced thresholds
h. Position and identification of taxiways, ramps, and parking
areas
i.
Type of runway surface
