7.3 Coverage and scale
Note 1.— A uniform scale for charts of this type cannot be specified due
to the varying degree of congestion of information in certain areas.
Note 2.— A linear scale based on the mean scale of the chart may be shown.
7.3.1 Recommendation.— Layout of sheet lines should be determined by the
density and pattern of the ATS route structure.
7.3.2 Large variations of scale between adjacent charts showing a
continuous route structure shall be avoided.
7.3.3 An adequate overlap of charts shall be provided to ensure continuity
of navigation.

7.4 Projection
7.4.1 Recommendation.— A conformal projection on which a straight line
approximates a great circle should be used.
7.4.2 Parallels and meridians shall be shown at suitable intervals.
7.4.3 Graduation marks shall be placed at consistent intervals along
selected parallels and meridians.

7.6 Culture and
topography
7.6.1 Generalized shore lines of all open water areas, large lakes and
rivers shall be shown except where they conflict with data more applicable to
the function of the chart.
7.6.2 Within each quadrilateral formed by the parallels and meridians, the
area minimum altitude shall be shown, except as provided for in 7.6.3.
Note 1.— Quadrilaterals formed by the parallels and meridians normally
correspond to the whole degree of latitude and longitude. Regardless of the
chart scale being used, the area minimum altitude relates to the consequent
quadrilateral.
Note 2. — Refer to the Procedures for Air Navigation — Aircraft Operations
(PANS OPS, Doc 8168), Volume II, Part I, Section 2, Chapter 1, 1.8, for method
for determination of area minimum altitude.
7.6.3 Recommendation.— In areas of high latitude where it is determined by
the appropriate authority that True North orientation of the chart is
impractical, the area minimum altitude should be shown within each
quadrilateral formed by reference lines of the graticule (grid) used.
7.6.4 Where charts are not True North orientated, this fact and the
selected orientation used shall be clearly indicated.

7.8 Bearings, tracks
and radials
7.8.1 Bearings, tracks and radials shall be magnetic, except as provided
for in 7.8.2. Where bearings and tracks are additionally provided as true
values for RNAV segments, they shall be shown in parentheses to the nearest
tenth of a degree, e.g. 290° (294.9°T).
7.8.2 Recommendation.— In areas of high latitude where it is determined by
the appropriate authority that reference to Magnetic North is impractical,
another suitable reference, i.e. True North or Grid North, should be used.
7.8.3 Where bearings, tracks or radials are given with reference to True
North or Grid North, this shall be clearly indicated. When Grid North is used,
its reference grid meridian shall be identified.

All ATS
routes
|
|
|
|
|
|
|
a) the radio navigation aids associated with the air traffic
services system together with their names, identifications, frequencies and
geographical coordinates in degrees, minutes and seconds;
b) in respect of DME, additionally the elevation of the
transmitting antenna of the DME to the nearest 30 m (100 ft);
c) an indication of
all designated airspace, including lateral and vertical limits and the
appropriate class of airspace;
d) All ATS routes for en-route flight including route
designators, the track to the nearest degree in both directions along each
segment of the routes and, where established, the designation of the navigation
specification(s) including any limitations and the direction of traffic flow;
Note.— Guidance material on the organization of ATS routes
for en-route flight publication which may be used to facilitate charting is
contained in the Aeronautical Information Services Manual (Doc 8126).
e) all significant points which define the ATS routes and
are not marked by the position of a radio navigation aid, together with their
name-codes and geographical coordinates in degrees, minutes and seconds;
f) in respect of
waypoints defining VOR/DME area navigation routes, additionally, 1) the station
identification and radio frequency of the reference VOR/DME; 2) the bearing to
the nearest tenth of a degree and the distance to the nearest two-tenths of a
kilometre (tenth of a nautical mile) from the reference VOR/ DME, if the
waypoint is not collocated with it;
g) an indication of
all compulsory and “on-request” reporting points and ATS/MET reporting points;
h) the distances to the nearest kilometre or nautical mile
between significant points constituting turning points or reporting points;
Note.— Overall
distances between radio navigation aids may also be shown.
i) change-over points
on route segments defined by reference to very high frequency omnidirectional
radio ranges, indicating the distances to the nearest kilometre or nautical
mile to the navigation aids;
Note.— Change-over points established at the mid-point
between two aids, or at the intersection of two radials in the case of a route
which changes direction between the aids, need not be shown for each route
segment if a general statement regarding their existence is made.
j) minimum en-route altitudes and minimum obstacle clearance
altitudes, on ATS routes to the nearest higher 50 metres or 100 feet (see Annex
11, 2.22);
k) communication
facilities listed with their channels and, if applicable, logon address and
satellite voice communications (SATVOICE) number; and
l) air defence
identification zone (ADIZ) properly identified. Note.— ADIZ procedures may be
