9.8.6 Where a surface movement guidance and control
system is provided by selective switching of stop bars and
taxiway centre line lights, the following requirements shall be
met:
a) taxiway routes which are indicated by illuminated
taxiway centre line lights shall be capable of being
terminated by an illuminated stop bar;
b) the control circuits shall be so arranged that when a stop
bar located ahead of an aircraft is illuminated, the
appropriate section of taxiway centre line lights beyond
it is suppressed; and
c) the taxiway centre line lights are activated ahead of an
aircraft when the stop bar is suppressed.
Note 1.— See Sections 5.3.16 and 5.3.19 for specifications
on taxiway centre line lights and stop bars, respectively.
Note 2.— Guidance on installation of stop bars and
taxiway centre line lights in surface movement guidance and
control systems is given in the Aerodrome Design Manual,
Part 4.
9.8.7 Recommendation.— Surface movement radar for
the manoeuvring area should be provided at an aerodrome
intended for use in runway visual range conditions less than a
value of 350 m.
9.8.8 Recommendation.— Surface movement radar for
the manoeuvring area should be provided at an aerodrome
other than that in 9.8.7 when traffic density and operating
conditions are such that regularity of traffic flow cannot be
maintained by alternative procedures and facilities.
Note.— Guidance on the use of surface movement radar is
given in the Manual of Surface Movement Guidance and
Control Systems (SMGCS) and in the Air Traffic Services
Planning Manual (Doc 9426).
9.9 Siting of equipment and installations
on operational areas
Note 1.— Requirements for obstacle limitation surfaces are
specified in 4.2.
Note 2.— The design of light fixtures and their supporting
structures, light units of visual approach slope indicators,
signs, and markers, is specified in 5.3.1, 5.3.5, 5.4.1 and 5.5.1,
respectively. Guidance on the frangible design of visual and
non-visual aids for navigation is given in the Aerodrome
Design Manual (Doc 9157), Part 6.
9.9.1 Unless its function requires it to be there for air
navigation purposes, no equipment or installation shall be:
a) on a runway strip, a runway end safety area, a taxiway
strip or within the distances specified in Table 3-1,
column 11, if it would endanger an aircraft; or
b) on a clearway if it would endanger an aircraft in the air.
9.9.2 Any equipment or installation required for air
navigation purposes which must be located:
a) on that portion of a runway strip within:
1) 75 m of the runway centre line where the code
number is 3 or 4; or
2) 45 m of the runway centre line where the code
number is 1 or 2; or
b) on a runway end safety area, a taxiway strip or within
the distances specified in Table 3-1; or
c) on a clearway and which would endanger an aircraft in
the air;
shall be frangible and mounted as low as possible.
9.9.3 Existing non-visual aids need not meet the
requirement of 9.9.2 until 1 January 2010.
9.9.4 Recommendation.— Any equipment or installation
required for air navigation purposes which must be located on
the non-graded portion of a runway strip should be regarded
