the procedures specialist.
11.7.3 Recommendation.- In areas where relief is
lower than specifed in 11.7.2, all relief exceeding 150 m
(500fi) above the aerodrome elevation should be shown by
smoothed contour lines, contour values and layer tints printed
in brown. Appropriate spot elevations, including the highest
elevation within each top contour line, should also be shown
printed in black.
Note 1.- The next higher suitable contour line appearing
on base topographic maps exceeding 150 m (5009) above the
aerodrome elevation may be selected to start layer tinting.
Note 2.- An appropriate brown coloul; on which half-tone
layer tinting is to be based, is specifed in Appendix 3 -
Colour Guide for contours and topographic fiatures.

pattern from the air shall be shown by the appropriate symbol.
Abandoned aerodromes shall be identified as abandoned.
11.10.1.2 The runway pattern, at a scale sufficiently large
to show it clearly, shall be shown for:
1) the aerodrome on which the procedure is based;
2) aerodromes affecting the traffic pattern or so situated as
to be likely, under adverse weather conditions, to be
mistaken for the aerodrome of intended landing.
1 1.10.1.3 The aerodrome elevation shall be shown to the
nearest metre or foot in a prominent position on the chart.
1 1.10.1.4 The threshold elevation or, where applicable,
the highest elevation of the touchdown zone shall be shown to
the nearest metre or foot.
