engines.
Note.- As a minimum, the width of the shoulders would
need to cover the outer engine of the most demanding
aeroplane and thus may be wider than the associated runway
shoulders.
3.3.13 Recommendation.- The strength of runway turn
pad shoulders should be capable of withstanding the
occasional passage of the aeroplane it is designed to serve
without inducing structural damage to the aeroplane and to
the supporting ground vehicles that may operate on the
shouldel:
3.4 Runway strips
Slopes on runway turn pads
3.3.8 Recommendation.- The longitudinal and
transverse slopes on a runway turn pad should be suficient to
prevent the accumulation of water on the su$ace and facilitate
rapid drainage of su$ace watel: The slopes should be the
same as those on the adjacent runway pavement su$ace.
Strength of runway turn pads
3.3.9 Recommendation.- The strength of a runway turn
pad should be at least equal to that of the a~i'joiningr unway
which it serves, due consideration being given to the fact that
the turn pad will be subjected to slow-moving traffic making
hard turns and consequent higher stresses on the pavement.
General
3.4.1 A runway and any associated stopways shall be
included in a strip.
Length of runway strips
3.4.2 A strip shall extend before the threshold and beyond
the end of the runway or stopway for a distance of at least:
- 60 m where the code number is 2, 3 or 4;
- 60 m where the code number is 1 and the runway is an
instrument one; and
Chapter 3 Annex 14 -Aerodromes
- 30 m where the code number is 1 and the runway is a
non-instrument one.
c) within 45 rn of the runway centre line of a precision
approach runway category I where the code number is 1
or 2.
Width of runway strips No mobile object shall be permitted on this part of the runway
strip during the use of the runway for landing or take-off.
3.4.3 A strip including a precision approach runway shall,
wherever practicable, extend laterally to a distance of at least:
- 150 m where the code number is 3 or 4; and Grading of runway strips
3.4.8 Recommendation.- That portion of a strip of an
instrument runway within a distance of at least:
- 75 m where the code number is 1 or 2;
on each side of the centre line of the runway and its extended
centre line throughout the length of the strip. - 75 m where the code number is 3 or 4: and
3.4.4 Recommendation.- A strip including a non- - 40 m where the code number is 1 or 2;
precision approach runway should extend laterally to a
distance of at least: from the centre line of the runway and its extended centre line
should provide a graded area for aeroplanes which the nmway
is intended to serve in the event of an aeroplane running
off the runway.
- I50 m where the code number is 3 or 4; and
- 75 m where the code number is 1 or 2;
Note.- Guidance on grading of a greater area of a strip
including a precision approach runway where the code
number is 3 or 4 is given in Attachment A, Section 8.
on each side of the centre line of the runway and its extended
centre line throughout the length of the strip.
3.4.5 Recommendation.- A strip including a noninstrument
runway should extend on each side of the centre
line of the runway and its extended centre line throughout the
length of the strip, to a distance of at least:
3.4.9 Recommendation.- That portion of a strip of a
non-instrument runway within a distance of at least:
- 75 m where the code number is 3 or 4;
- 75 m where the code number is 3 or 4; - 40 m where the code number is 2; and
- 40 m where the code number is 2; and - 30 m where the code number is I ;
- 30 m where the code number is 1 from the centre line of the runway and its extended centre line
should provide a graded area for aeroplanes which the nmway
is intended to serve in the went of an aeroplane running
Objects on runway strips off the runway.
Note.- See 9.9 for information regarding siting of
equipment and installations on runway strips.
3.4.10 The surface of that portion of a strip that abuts a
runway, shoulder or stopway shall be flush with the surface of
the runway, shoulder or stopway.
3.4.6 Recommendation, An object situated on a runway
strip which may endanger aeroplanes should be regarded as
an obstacle and should, as far as practicable, be removed. 3.4.1 1 Recommendation.- That portion of a strip to at
least 30 m before a threshold should be prepared against blast
erosion in order to protect a landing aeroplane ji-om the
danger of an exposed edge.
3.4.7 No fixed object, other than visual aids required for
air navigation purposes and satisfying the relevant frangibility
