CHARTING/AERONAUTICAL INFORMATION PUBLICATION (AIP)
8.1 GENERAL
Material relating to the publication of charts is contained in Annex 4 as follows:
a) Standard Arrival Chart — Instrument (STAR) — ICAO, in Annex 4, Chapter 10; and
b) Instrument Approach Chart — ICAO, in Annex 4, Chapter 11.
8.2 CHARTED ALTITUDES/FLIGHT LEVELS
In addition to minimum IFR altitudes established for each segment of the procedure, procedure altitudes/heights will
also be provided. Procedure altitudes/heights will, in all cases, be at or above any minimum crossing altitude associated
with the segment. Procedure altitude/height will be established taking into account the air traffic control needs for that
phase of flight. (See Table I-4-8-1.)
8.3 ARRIVAL
In some cases it is necessary to designate arrival routes from the en-route structure to the initial approach fix. Only
those routes that provide an operational advantage are established and published. These routes take local air traffic flow
into consideration.
8.4 APPROACH
8.4.1 General
8.4.1.1 Optimum and maximum descent gradients and angles are specified depending on the type of procedure
and the segment of the approach. The descent gradient(s)/angles used in the construction of the procedure are published
for the final approach segment. It is preferable that they also be published for the other approach segments, where
appropriate.
8.4.1.2 Where distance information is available, descent profile advisory information for the final approach
should be provided to assist the pilot to maintain the calculated descent gradient. This should be a table showing
altitudes/heights through which the aircraft should be passing at each 2 km or 1 NM as appropriate.
