must not have any step down from the runway, the runway shoulder or the stopway exceeding 25 mm.

Note   CASA recommends that within the graded area of the runway strip, constructions such as plinths, runway ends, paved taxiway edges etc. are such as to avoid presenting a non-frangible buried vertical face to aircraft wheels in the runway direction, in soft ground conditions.

       (2) Maintenance must ensure that no step up to the runway strip from the runway, the runway shoulder or stopway exceeds 25 mm.

       (3) Effective drainage (but not involving open drains) must ensure that water does not pool or pond in the graded area of a runway strip.

        Note   Where deemed necessary for proper drainage, an open-air storm water conveyance is permitted in the non-graded portion of a runway strip. However, for such cases, CASA recommends that the storm water conveyance should be placed as far as possible from the runway.

       (4) The area of a runway strip at the end of a runway that is at least 30 m from the runway threshold must be constructed in such a way as to resist erosion from jet blast, prop wash or rotor wash so that a landing aeroplane is not endangered by the effects of such erosion on the runway, runway shoulder or stopway edge.

Note   See sections 6.16 to 6.25 for runway strip standards.

6.23 Composition of runway strips

        The graded portion of a runway strip must be prepared, constructed and maintained so as to minimise hazards arising from differences in the load-bearing capacity of aeroplanes which the runway is intended to serve, in the event of an aeroplane running off the runway.

6.24 Objects or structures on runway strips

Note   The runway strip forms part of the obstacle restriction area. CASA approval is required for objects, other than approved visual and navigational aids, which are located within the obstacle restriction area. See subsection 7.02 (1).

       (1) A runway strip must be free of fixed objects or structures, other than visual or navigational aids for the guidance of aircraft or vehicles:

(a) within 77.5 m of the centreline of a code 4F precision approach CAT I, II or III runway; and

(b) within 60 m of the centreline of a code 3 or 4 precision approach CAT I, II or III runway; and

(c) within 45 m of the centreline of a code 1 or 2 precision approach CAT I runway.

       (2) Any fixed object or structure permitted to be on the runway strip (including visual or navigational aids) must be of low mass and frangibly mounted.

       (3) When a runway is in use for take-off or landing, no mobile object may be on any part of
