PUBLICATION OF INFORMATION RELATING TO
AERONAUTICAL CHARTS AND AERODROMES
(Paragraph 8, Part VIII — AIS refers)
INFORMATION REQUIRED
FOR THE PRODUCTION OF
AERONAUTICAL CHARTS
1. Area charts, including SID/STAR charts, should
always portray track/bearing, distance and minimum safe
altitude information.
2. Terminal procedures should be presented in a
graphic format.
3. Reporting points should always be identified,
whether compulsory or on request, and defined by
geographical coordinates.
4. Adequate distance information should be shown,
particularly where turns are involved. An average distance
based on a standard speed/rate of climb should be used.
5. For DME, TACAN and VORTAC stations, the
antenna elevation in metres (feet) MSL should be included
in all NOTAM related to new facilities and incorporated
into AIPs as permanent information. Similarly, information
is required in respect of the exact variation value which has
been used for the alignment of VORs. All subsequent
reorientations should be promulgated by NOTAM and
included in the AIP.
6. Geographical coordinates for navigation aids and
significant points should be indicated in degrees, minutes
and seconds and, as of 1 January 1998, be expressed in
relation to WGS-84.
7. Statements in AIPs concerning directional use of
ATS routes should be as positive as possible. Statements
such as “normally used” lead to congestion on charts due to
notes, and confusion is created as to whether the route can
be used in the direction required. Such ambiguity could be
avoided if only the heading relating to the preferential
direction were to be entered in the segment/heading column
of the AIP.
8. Publication of new or revised instrument approach
procedures should be accompanied by an Instrument
Approach Chart. In cases where this is not feasible (e.g. due
to short notice), the text of the related NOTAM should
contain at least the following information, as appropriate:
a) minimum sector altitude with reference facility;
b) transition altitude/level;
c) runway direction;
d) reference datum for height information and OCH;
e) turn limit of the procedure turn or base turn expressed
as a time/speed or distance;
f) turn altitude/height;
g) ILS glide path angle;
h) the height of the glide path at the specified fixes;
i) distance of the radio fix on the final approach to the
runway threshold;
j) ILS reference datum height (RDH);
k) ILS category;
l) missed approach point (MAPt);
