11.10.2.2 Recommendation.- Zfone or more obstacles
are the determining factor of an obstacle clearance altitude/
height, those obstacles should be identifed.
11.10.2.3 The elevation of the top of obstacles shall be
shown to the nearest (next higher) metre or foot.
11.10.2.4 Recommendation.- The heights of obstacles
above a datum other than mean sea level (see 11.10.2.3)
should be shown. When shown, they should be given in
parcnthcscs on the chart.
11.10.4.4 Radio navigation aids that might be used in
diversionary procedures together with their track-defining
characteristics, if any, shall be shown or indicated on the chart.
1 1.10.4.5 Radio communication frequencies, including
call signs, that are required for the execution of the procedures
shall be shown.
11.10.4.6 When required by the procedures, the distance
to the aerodrome fkom each radio navigation aid concerned
with the final approach shall be shown to the nearest kilometre
or nautical mile. When no track-defining aid indicates the
bearing of the aerodrome, the bearing shall also be shown to
the nearest degree.
11.10.2.5 When the heights of obstacles above a datum
other than mean sea level are shown, the datum shall be the 1 1.10.5 Minimum sector altitude or
aerodrome elevation except that, at aerodromes having an terminal arrival altitude
instrument runway (or runways) with a threshold elevation
more than 2 m (7 ft), below the aerodrome elevation, the chart The minimum sector altitude Or terminal arrival altitude
datum shall be the threshold elevation of the runway to which established by the competent authority shall be shown, with a
the instrument approach is related. clear indication of the sector to which it applies.
11.10.2.6 Where a datum other than mean sea level is
used, it shall be stated in a prominent position on the chart. 1 1.10.6 Portrayal of procedure tracks
11.10.2.7 Where an obstacle free zone has not been 11.10.6.1 The plan view shall show the following

shall be indicated.
a) the approach procedure track by an mowed continuous
line indicating the direction of flight;
11.10.3 Prohibited, restricted and danger areas
b) the missed approach procedure track by an mowed
Prohibited areas, restricted areas, and danger areas which may broken line;
affect the execution of the procedures shall be shown with
their identification and vertical limits. c) any additional procedure track, other than those
specified in a) and b), by an arrowed dotted line;
1 1.10.4 Radio communication facilities and
navigation aids
11.10.4.1 Radio navigation aids required for the
procedures together with their frequencies, identifications and
track-defining characteristics, if any, shall be shown. In the
case of a procedure in which more than one station is located
on the final approach track, the facility to be used for track
guidance for final approach shall be clearly identified. In
addition, consideration shall be given to the elimination from
the approach chart of those facilities that are not used by the
procedure.
11.10.4.2 The final approach fix (or final approach point
for an ILS approach procedure) and other essential fixes or
points comprising the procedure shall be shown and identified.
11.10.4.3 Recornmendation.- Thefinal approach fa (or
final approach point,for an ILS approach procedure) should be
identifed with its geographical coordinates in degrees,
minutes and seconds.
d) bearings, tracks, radials to the nearest degree and
distances to the nearest two-tenths of a kilometre or
tenth of a nautical mile or times required for the
procedure;
e) where no track-defining aid is available, the magnetic
bearing to the nearest degree to the aerodrome from the
radio navigation aids concerned with the final approach;
f ) the boundaries of any sector in which visual
manoeuvring (circling) is prohibited;
g) where specified the holding pattern and minimum
holding altitudeheight associated with the approach and
missed approach;
h) caution notes where required, prominently displayed on
the face of the chart.
1 1.10.6.2 Recommendation.- The plan view should
show the distance to the aerodrome >om each radio
navigation aid concerned with thefinal approach.
