CHAPTER 4. AERODROME OBSTACLE CHART -
ICAO TYPE B
This chart shall provide information to satisfy the following
functions:
a) the determination of minimum safe altitudesfheights
including those for circling procedures;
b) the determination of procedures for use in the event of
an emergency during take-off or landing;
c) the application of obstacle clearing and marking criteria;
and
d) the provision of source material for aeronautical charts.
4.2 Availability
4.2.1 Recommendation.- Aerodrome Obstacle Charts
- ICAO Type B should be made available, in the manner
prescribed in 1.3.2, for all aerodromes regularly used by
international civil aviation.
4.2.2 When a chart combining the specifications of
Chapters 3 and 4 is made available, it shall be called the
Aerodrome Obstacle Chart - ICAO (Comprehensive).
4.4.2 The horizontal scale shall be within the range of
1:10 000 to 1:20 000.
4.4.3 A horizontal linear scale showing both metres and
feet shall be included in the chart. When necessary, a linear
scale for kilometres and a linear scale for nautical miles shall
also be shown.
4.5 Format
The charts shall include:
a) any necessary explanation of the projection used;
b) any necessary identification of the grid used;
c) a notation indicating that obstacles are those which
penetrate the surfaces specified in Annex 14, Volume I,
Chapter 4;
d) a box for recording amendments and dates thereof;
e) outside the neat line, every minute of latitude and
longitude marked in degrees and minutes.
Note.- Lines of latitude and longitude may be shown
across the face of the chart.
4.3 Units of measurement
4.3.1 Elevations shall be shown to the nearest half-metre 4.6 Identification
or to the nearest foot.
The chart shall be identified by the name of the country in
4.3.2 Linear dimensions be shown to the nearest which the aerodrome is located, the name of the city or town,
half-mctrc. or area, which the aerodrome serves and the name of the
aerodrome.
4.4 Coverage and scale
4.4.1 The extent of each plan shall be sufficient to cover 4.7 Culture and topography
all significant obstacles.
4.7.1 Drainage and hydrographic details shall be kept to a
Note.- Isolated distant obstacles that would unnecessarily minimum.
increase the sheet size may be indicated by the appropriate
symbol and an arrow, provided that the distance and 4.7.2 Buildings and other salient features associated with
bearing from the aerodrome reference point and elevation are the aerodrome shall be shown. Wherever possible, they shall
given. be shown to scale.
ANNEX 4 4-1 1/11/01
Annex 4 -Aeronautical Charts Chapter 4
4.7.3 All objects, either cultural or natural, that project
above the take-off and approach surfaces specified in 4.9 or
the clearing and marking surfaces specified in Annex 14,
Volume I, Chapter 4 shall be shown.
4.7.4 Roads and railroads within the take-off and
approach area, and less than 600 m (2 000 ft) from the end of
the runway or runway extensions, shall be shown.
Note.- Geographical names of features may be shown if of
significance.
4.8 Magnetic variation
The chart shall show a compass rose orientated to the True
North, or a North point, showing the magnetic variation to the
nearest degrcc with the date of magnetic information and
annual change.
4.9 Aeronautical data
4.9.1 The charts shall show:
a) the aerodrome reference point and its geographical
coordinates in degrees, minutes and seconds;
b) the outline of the runways by a solid line;
C) the length and width of the runway;
d) the magnetic bearing to the nearest degree of the
runway and the runway number;
c) thc clcvation of the runway ccntrc linc at cach cnd of
the runway, at the stopway, at the origin of each takeoff
and approach area, and at each significant change
of slope of runway and stopway;
f) taxiways, aprons and parking areas identified as such,
and the outlines by a solid line;
g) stopways identified as such and depicted by a broken
line;
h) the length of each stopway;
i) clearways identified as such and depicted by a broken
line;
j) the length of each clearway;
k) take-off and approach surfaces identified as such and
depicted by a broken line;
1) take-off and approach areas;
Note.- The take-off area is described in 3.8.2.1.
The approach area consists of an area on the surface
of the earth lying directly below the approach surface
as specljied in Annex 14, Volume I, Chapter 4.
