Taxiway bearing strength

        The bearing strength of a taxiway must be:

(a) at least equal to the bearing strength of the runway it serves; or

(b) otherwise capable of bearing the weights and movement frequencies of the types of aeroplanes which the taxiway serves.

6.44 Taxiway shoulders

        A code C, D, E or F taxiway must have shoulders if it is available for use by turbine‑engined aeroplanes.

Note   Taxiway shoulders are otherwise optional but are recommended.

6.45 Width of taxiway shoulders

       (1) The total width of the taxiway and the shoulders must not be less than the following (the minimum taxiway shoulder width):

       (a) for a code F taxiway — 44 m;

(b) for a code E taxiway — 38 m;

(c) for a code D taxiway — 34 m;

(d) for a code C taxiway — 25 m.

       (2) The minimum taxiway shoulder width must be maintained along the whole length of a taxiway, including:

(a) on its curved sections; and

(b) at junctions and intersections with runways and other taxiways.

Note   The requirement in subsection (1) applies despite any increase in the surface width of the taxiway itself on its curved sections, or at junctions or intersections with runways or other taxiways.

6.46 Surface of taxiway shoulders

       (1) Taxiway shoulders must:

(a) be on both sides of the taxiway; and

(b) slope downwards and away from the taxiway surface; and

(c) be resistant to aeroplane engine blast erosion; and

(d) if they have a step down from the taxiway surface — not step down by more than 25 mm; and

(e) if a runway intersects with the taxiway — merge with the runway shoulder.

Note   CASA recommends that a taxiway shoulder should also be capable of the following:
       (a) supporting an aeroplane running off the taxiway onto a shoulder without the aeroplane sustaining any structural damage;
       (b) supporting emergency and service vehicles.
       (2) If a sealed taxiway is designed for a jet engine aircraft whose engines overhang the taxiway shoulders, the surface of the shoulders must be sealed along their length to a width of at least 3 m from each taxiway edge.

6.47 Taxiway strips

       (1) A taxiway, other than an aeroplane taxilane, must be located on a taxiway strip which includes graded areas on either side of the taxiway.

Note   See Figure 6.47 (1). The taxiway sits within the graded area and overall taxiway strip.

       (2) The surface of the graded area of a taxiway strip where it abuts a taxiway or a taxiway shoulder must not have any step down from the taxiway or a taxiway shoulder exceeding 25 mm.

       (3) Any step up to the taxiway strip from a taxiway or taxiway shoulder must
