Communications frequencies for the major airports shown on an area chart are given in a block as
illustrated above.

GENERALIZED TERRAIN CONTOURS

Terrain information may be depicted on area charts when terrain within the area chart coverage rises
more than 4000 feet above the main airport.

Generalized terrain contour lines and contour values are depicted. Gradient tints indicate the
elevation change between contour intervals. Contour lines, values and tints are printed in brown.
Within contour intervals some, but not all, terrain high points may be included along with their
elevation above mean sea level for use as an additional reference.

THE TERRAIN CONTOUR INFORMATION DEPICTED DOES NOT ASSURE CLEARANCE ABOVE
OR AROUND TERRAIN OR MAN-MADE STRUCTURES. THERE MAY BE HIGHER UNCHARTED
TERRAIN OR MAN-MADE STRUCTURES WITHIN THE SAME VICINITY. TERRAIN CONTOUR
INFORMATION IS USEFUL FOR ORIENTATION AND GENERAL VISUALIZATION OF TERRAIN.
IT DOES NOT REPLACE THE MINIMUM ALTITUDES DICTATED BY THE AIRWAY AND AIR
ROUTE STRUCTURE. Furthermore, the absence of terrain contour information does not ensure the
absence of terrain or structures
.
