11.6 Identification

11.6.1 The chart shall be identified by the name of the city or town, or area, which the aerodrome serves, the name of the aerodrome, the abbreviation of the type of radio navigation aid(s) on which the instrument approach procedure or the visual manoeuvring (circling) procedure is established and the designator of the runway where applicable.

11.6.2 Where the instrument approach procedure is limited to certain categories of aircraft this shall be shown in parentheses at the end of the identification.

Questions:

1. What shall the coverage of the chart be?

2. What should the format of the chart be?

3. What projection shall be used?

4. How shall the chart be identified?

CHAPTER 12. VISUAL APPROACH CHART – ICAO

Part 1

12.1 Function

12.1.1 This chart shall provide flight crews with information which will enable them to transit from the en-route descent to approach phases of flight to the runway of intended landing by means of visual reference.

12.2 Applicability

12.2.1 The Visual Approach Chart — ICAO shall be made available in the manner prescribed in 1.3.2 for all aerodromes used by international civil aviation where:

1. only limited navigation facilities are available; or

2. radio communication facilities are not available; or

3. no adequate aeronautical charts of the aerodrome and its surroundings at 1:500 000 or greater scale are available: or

4. visual approach procedures have been established.

12.3 Scale

12.3.1 The scale shall be sufficiently large to permit depiction of significant features and indication of the aerodrome layout.

12.3.2 Recommendation. - The scale should not be smaller than 1:500000.

Note. - A scale of 1:250 000 or 1:200 000 is preferred.

12.3.3 Recommendation. - When an Instrument Approach Chart is available for a given aerodrome, the Visual Approach Chart should be drawn to the same scale.

12.4 Format

12.4.1 Recommendation. - The sheet size should be 210  148 mm 18.27  5.82 in).

Note. - It would be advantageous to print the charts in several colours, selected to provide maximum legibility in varying degrees and kinds of light.

Questions:

1. What is the function of the chart?

2. What is the applicability of the chart?

3. What scale shall be used?

4. What should the format of the chart be?

CHAPTER 12. VISUAL APPROACH CHART – ICAO

Part 2

12.5 Projection

12.5.1 A conformal projection on which a straight line approximates a great circle shall be used.

12.5.2 Recommendation. - Graduation marks should be placed at consistent intervals along the neat lines.

12.6 Identification

12.6.1 The chart shall be identified by the name of the city or town which the aerodrome serves and the name of the aerodrome.

12.7 Culture and topography

12.7.1 Natural and cultural landmarks shall be shown (e.g. bluffs, cliffs, sand dunes, cities, towns, roads, railroads, isolated lighthouses, etc.).

12.7.1.1 Recommendation. - Geographical place names should be included only when they are required to avoid confusion or ambiguity.

12.7.2 Shore lines, lakes, rivers and streams shall be shown.

12.7.3 Relief shall be shown in a manner best suited to the particular elevation and obstacle characteristics of the area covered by the chart.

12.7.4 Recommendation. - When shown, spot elevations should be carefully selected.

Note. - The value of certain spot elevations heights in relation to both mean sea level and aerodrome elevation may be given.

12.7.5 The figures relating to different reference levels shall be clearly differentiated in their presentation.
