(a)That portion of a strip of an instrument runway within a distance of at least:

(1)75 m where the code number is 3 or 4; and

(2)40 m where the code number is 1 or 2; from the centre line of the runway and its extended centre line should be prepared or constructed so as to minimise hazards arising from differences in load-bearing capacity to aeroplanes which the runway is intended to serve in the event of an aeroplane running off the runway.

(b)That portion of a strip containing a non-instrument runway within a distance of at least:

(1)75 m where the code number is 3 or 4;

(2)40 m where the code number is 2; and

(3)30 m where the code number is 1; from the centre line of the runway and its extended centre line should be prepared or constructed so as to minimise hazards arising from differences in load-bearing capacity to aeroplanes which the runway is intended to serve in the event of an aeroplane running off the runway.
