Instructions under CAR 235A — minimum runway width for aeroplanes
This instrument commences on 1 March 2012.
This instrument specifies the minimum runway width applicable to an aeroplane or a type of aeroplane.
I issue the instructions in Schedule 1.
Schedule 1 Instructions
(1) In this Schedule:
an aeroplane’s reference field length is:
(a) in the case of an aeroplane to which Civil Aviation Order 20.7.1B applies — the balanced field length; or
(b) in the case of any other aeroplane — the take-off distance that the aeroplane requires for take-off.;
calculated in accordance with subclause (2).
(2) For subclause (1):
the balanced field length or the take-off distance that an aeroplane requires for take-off is the balanced field length, or the take-off distance, that, according to the aeroplane’s flight manual, the aeroplane requires for take-off:
(a) on a level runway; and
(b) at maximum certificated take-off weight; and
(c) in still air; and
(d) at sea level; and
(e) in standard atmospheric conditions.
(3) For these instructions:
the aerodrome reference code (code number and code letter) for an aeroplane is obtained from Table 1 as follows:
(a) the code number for the aeroplane is the number in Column 1 opposite the applicable aeroplane reference field length in Column 2;
(b) the code letter for the aeroplane is the letter in Column 3 opposite the applicable wing span or outer main gear wheel span in Columns 4 and 5, being whichever occurs later.
Table 1 — Aerodrome reference code
Aeroplane reference field length
Outer main gear wheel span
Less than 800 m
Up to but not including 15 m
Up to but not including 4.5 m
800 m up to but not including 1 200 m
15 m up to but not including 24 m
4.5 m up to but not including 6 m
1 200 m up to but not including 1 800 m
24 m up to but not including 36 m
6 m up to but not including 9 m
1 800 m and over
36 m up to but not including 52 m
9 m up to but not including 14 m
52 m up to but not including 65 m
9 m up to but not including 14 m
65 m up to but not including 80 m
14 m up to but not including 16 m
Note Table 1 is in accordance with Table 2.1-1 of the Manual of Standards Part 139 — Aerodromes, which addresses the use of ICAO aerodrome reference codes to specify standards for aerodrome facilities.
2 Minimum runway width for aeroplanes
Subject to clauses 3 and 4, the minimum runway width for an aeroplane or aeroplane type is obtained by finding the aerodrome reference code (code number and code letter) applicable to the aeroplane or aeroplane type and applying the code to the minimum runway width data provided in Table 2, with the minimum runway width required being at the intersection of the row that specifies the aeroplane’s code number and the column that specifies the code letter.
Table 2 — Minimum runway widths
1 The runway width for certain aeroplanes may be reduced to 15 m or 10 m, as applicable, in accordance with clause 3 or 4.
3 Minimum runway width for certain small aeroplanes
(1) Subject to subclauses (2) and (3) and clause 4, the minimum runway width for an aeroplane that has a maximum certificated take-off weight of not more than 5 700 kg is 15 m.
(2) The minimum runway width for an aeroplane that has a maximum certificated take-off weight of not more than 2 000 kg and is taking off from, or landing at, a place with little or no cross-wind is 10 m.
(3) For an aeroplane engaged in agricultural operations, which would otherwise be subject to subclause (1), the minimum runway width is 10 m.
4 Minimum runway width for certain small aeroplanes
The minimum runway width for an aeroplane that has a maximum certificated take‑off weight of not more than 5 700 kg and is taking off from, or landing at, a place that meets the requirements of paragraph 92 (1) (d) of CAR 1988 is 10 m.
