CHAPTER 18. AERONAUTICAL NAVIGATION CHART -
ICAO SMALL SCALE
18.1 Function
This chart shall:
1) serve as an air navigation aid for flight crews of long
range aircraft at high altitudes;
2) provide selective checkpoints over extensive ranges for
identification at high altitudes and speeds, which are
required for visual confirmation of position;
3) provide for continuous visual reference to the ground
during long range flights over areas lacking radio or
other electronic navigation aids, or over areas where
visual navigation is preferred or becomes necessary;
4) provide a general purpose chart series for long range
flight planning and plotting.
18.3.4 Linear scales for kilometres and nautical miles
arranged in the following order:
- kilometres,
- nautical miles,
with their zero points in the same vertical line shall be shown
in the margin.
18.3.5 Recommendation.- The length of the linear
scale should be not less than 200 mm (8 in).
18.3.6 A conversion scale (metreslfeet) shall be shown in
the margin.
18.4 Format
18.4.1 The title and marginal notes shall be in one of the
working languages of ICAO.
18.2 Availability
Note.- The language of the publishing country or any

Aeronautical Chart Manual (Doc 8697).
Note 2.- The sheet size may represent the maximum press
size available to the producing agency.
18.3.2 The scale shall be in the range of 1:2 000 000 to
1:5 000 000.
18.3.3 The scale of the chart shall be substituted in the
title for the words "Small Scale".
18.5 Projection
18.5.1 A conformal (ortlio~riorphic) projection st~all be
used.
18.5.1.1 The name and basic parameters of the projection
shall be shown in the margin.
18.5.2 Parallels shall be shown at intervals of 1"
18.5.2.1 Graduations on thc parallels shall bc shown at
sufficiently close intervals compatible with the latitude and the
scale of the chart.
18.5.3 Meridians shall be shown at intervals compatible
with the latitude and the scale of the chart.
