extended continuously through the continents.
Note 2.- Gravity-related heights (elevations) are also
referred to as orthometric heights while distances of points
above the ellipsoid are refrred to as ellipsoidal heights.
2.1 8.2.2 In addition to the elevations referenced to MSL,
for the specific surveyed ground positions, geoid undulation
(referenced to the WGS-84 ellipsoid) for those positions shall
also be published as specified for a particular chart.
Note.- Specifications governing the determination and
reporting (accuracy of field work and data integrity) of
elevation and geoid undulation at specific positions at
aerodromes/heliports are given in Annex 14, Volumes I and II,
Chapter 2, and in Table 2 of Appendices 5 and I , respectively.
2.18.2.3 The order of chart resolution of elevation and
geoid undulation shall be that specified for a particular chart
series and in accordance with Appendix 6, Table 2.
2.1 8.3 Temporal reference system
2.1 8.3.1 The Gregorian calendar and Coordinated
Universal Time (UTC) shall be used as the temporal reference
systcm.
2.18.3.2 When a different temporal reference system is
used for charting, this shall be indicated in GEN 2.1.2 of the
Aeronautical Information Publication (AIP).

CHAPTER 3. AERODROME OBSTACLE CHART -
ICAO TYPE A (OPERATING LIMITATIONS)
3.1 Function Note.- When the production of the charts would be
expedited thereby, a scale of l:20 000 may be used.
This chart, in combination with the Aerodrome Obstacle Chart
- ICAO Type C 01. with the relevant information published in 3.4.4 The vertical scale shall be ten times the horizontal
the AIP, shall provide the data necessary to enable an operator scale.
to comply with the operating limitations of Annex 6, Parts I
and 11, Chapter 5, and Part 111, Chapter 3. 3.4.5 Linear scales. Horizontal and vertical linear scales
showing both metres and feet shall be included in the charts.
3.2 Availability
3.5 Format
3.2.1 Aerodrome Obstacle Charts - ICAO Type A
(Operating Limitations) shall be made available in the manner
prescribed in 1.3.:! for all aerodromes regularly used by
international civil aviation, except for those aerodromes where
there are no obstacles in the take-off flight path areas.
3.2.2 Where a chart is not required because no obstacles
exist in the take-off flight path area, a notification to this effect
shall be published.
3.5.1 The charts shall depict a plan and profile of each
runway, any associated stopway or clearway, the take-off
flight path area and obstacles.
3.5.2 The profile for each runway, stopway, clearway and
the obstacles in the take-off flight path area shall be shown
above its corresponding plan. The profile of an alternative
take-off flight path area shall comprise a linear projection of
the full take-off flight path and shall be disposed above its
corresponding plan in the manner most suited to the ready
interpretation of the information.
3.3 Units of measurement 3.5.3 A profile grid shall be ruled over the entire profile
area exclusive of the runway. The zero for vertical coordinates
3.3.1 Elevatima shall be shown to the nearest half-metre shall be mean sea level. The zero for horizontal coordinates
or to the nearest foot. shall be the end of the runway finthest from the take-off flight
path area concerned. Graduation marks indicating the sub-
3.3.2 ~i~~~ dimensions shall be shown to the nearest divisions of intervals shall be shown along the base of the grid
ha1 f-metre. and along the vertical margins.
3.4 Coverage and scale
3.5.3.1 Recommendation.- The vertical grid should
have intervals of 30 rn (IOOP) and the horizontal grid should
have intervals of 300 m (I 000f).
3.5.4 The chart shall include:
3.4.1 The extent of each plan shall be sufficient to cover
all obstacles.
a) a box for recording the operational data specified in
Note.- Isolated distant obstacles that would unnecessarily 3.8.3;
increase the sheet .size may be indicated by the appropriate
symbol and an arrow, provided that the distance and bearing b) a box for recording amendments and dates thereof.
from the end of the runway farthest removed and the elevation
are given.
3.6 Identification
3.4.2 The horizontal scale shall be within the ran"ee of
1:10 000 to 1:15 000. The chart shall be identified by the name of the country in
which the aerodrome is located, the name of the city or town,
3.4.3 Recomm.endation.- The horizontal scale should or area, which the aerodrome serves, the name of the
be 1:lO 000. aerodrome and the designator(s) of the mnway(s).
