different slopes on a RESA must be as gradual as possible.

       (9) No portion of a RESA may project above the approach or take-off climb surfaces of the runway.

       (10) A RESA must be free of fixed objects or structures, other than visual or navigational aids for the guidance of aircraft or vehicles.

       (11) Any fixed object or structure permitted to be on a RESA must be of low mass and frangibly mounted.

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

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

6.27 Clearways

        A clearway, consisting of an obstruction-free rectangular plane, may be provided at the end of a runway.

Note   The purpose of a clearway is to allow an aeroplane taking off to make a portion of its initial climb to at least 35 ft (10.7 m) above the ground by the end of the clearway.

6.28 Location of clearways

        A clearway must start at the end of the TORA.

Note   The area between the end of the runway and the end of the runway strip is treated as a clearway.

6.29 Dimensions of clearways

       (1) The maximum length of any clearway must not exceed half the length of the TORA.

       (2) The width of a clearway must be at least:

(a) for a code 3 or 4 runway  150 m; and

(b) for a code 2 runway  80 m; and

(c) for a code 1 runway — 60 m.

       (3) A clearway must be at least as wide as the width of the runway strip.

6.30 Slopes on clearways

        No portion of the surface below a clearway may project above a plane with an upward slope of 1.25%, the lower limit of which is a horizontal line that:

(a) is perpendicular to the vertical plane containing the runway centreline; and

(b) passes through a point located on the runway centreline at the end of the TORA.

6.31 Objects or structures on clearways

       (1) A clearway must be free of fixed or mobile objects or structures, other than visual or navigational aids for the guidance of aircraft or vehicles.

       (2) Any fixed objects or structures permitted to be on the clearway must be of low mass and frangibly mounted.

6.32 Stopways

        A stopway on which an aeroplane may be stopped in the event of an abandoned take-off may be provided at the end of a runway.

Note   A stopway
