Chapter 5 Annex 14 - Aerodromes
Note 4.- See 5.4.3 for specifications on runway vacated c) on a taxiway intended for use in RVR conditions of less
signs. than a value of 350 m, the longitudinal spacing should not
exceed 15 m.
5.3.16.8 Taxiway centre line lights shall be in accordance
with the specifications of: 5.3.16.1 3 Recommendation.- Taxiway centre line lights
on a taxiway curve should continue from the straight portion of
a) Appendix 2, Figure A2- 12, A2-13, or A2-14 for the taxiway at a constant distancefrom the outside edge of the
taxiways intended for use in runway visual range taxiway curve. The lights should bespaced at intervals such that
conditions of less than a value of 350 m; and a clear indication of the curve is provided.
h) Appendix 2, Figure A2-15 or A2-16 for other taxiways.
5.3.16.9 Recommendation.- Where higher intensities
are required, fmm an operational point of view, taxiway centre
line lights on rapid exit taxiways intended for use in runway
visual range conditions less than a value of 350 m should be
in accordance with the specifications of Appendix 2,
Figure A2-12. The number of levels of brilliancy settings for
these lights should be the same as that for the runway centre
line lights.
5.3.16.14 Recommendation.- On a taxiway intended
fir use in RVR conditions of less than a value of 350 m, the
lights on a curve should not exceed a spacing of 15 m and on
a curve of less than 400 m radius the lights should be spaced
at intervals of not greater than 7.5 m. This spacing should
extend for 60 m before and after the curve.
Note 1.- Spacings on curves that have been found suitable
for a taxiway intended for use in RVR conditions of 350 m or
greater are:
5.3.16.1 0 Recommendation.- Where taxiway centre Curve radius Light spacing
line lights are specified as components of an advanced su$ace
movement guidance and control system and where, from an up to 400 m 7.5 m
operational point of view, higher intensities are required to 401 m to 899 m I5 m
maintain ground movements at a certain speed in vey Inw 900 m or greater 30 m
visibilities or in bright daytime conditions, taxiway centre line
lights should be in accordance with the specifications of Note 2.- See 3.9.5 and Figure 3-2.
Appendix 2, Figure A2-17, A2-18 or A2-19.
Note.- High-intensity centre line lights should only be Taxiway centre line lights
used in case of an absolute necessity and following a specific on rapid exit taxiways
study.
Location
5.3.16.1 1 Recommendation.- Taxiway centre line lights
should normally be located on the taxiway centre line marking,
except that they may be offset by not more than 30 cm where it
is not practicable to locaie them on the marking.
Taxiway centre line lights
on taxiways
5.3.16.15 Recommendation.- Taiiway centre line lights
on a rapid exit taxiway should commence at a point at least
60 m before the beginning of the taxiway centre line curve and
continue beyond the end of the curve to a point on the centre
line of the taxiway where an aeroplane can be expected to
reach nnrmal taxiing speed. The lights on that portion parallel
to the runway centre line should always be at least 60 cmfrom
any row of runway centre line lights, as shown in Figure 5-25.
5.3.16.16 Recommendation.- The lights should be
spaced at longitudinal intervals of not more than 15 m, except
that, where runway centre line lights are not provided, a
greater interval not exceeding 30 m may be used.
5.3.16.12 Recommendation.- Taxiway centre line lights
on a straight section of a taxiway should be spaced at longi- TILx.way centre line lights
tudinal intervals of not more than 30 m, except that: on other exit taxiways
a) larger intervals nnt exceeding 60 m may he u~edw here,
because of the prevailing meteorological conditiok, Location
adequate guidance is provided by such spacing;
5.3.16.17 Recommendation, Taxiway centre line
b) intervals less than 30 m should be provided on short lights on exit taxiways other than rapid exit taxiways should
straight sections; and commence at the point where the taxiway centre line marking
