(ii)45 m of the runway centre line where the code number is 1 or 2; or

(2)on a runway end safety area, a taxiway strip, or within the distances specified in Table D-1; or

(1)is situated within 240 m from the end of the strip and within:

(i)60 m of the extended runway centre line where the code number is 3 or 4; or

(ii)45 m of the extended runway centre line where the code number is 1 or 2; or

(2)penetrates the inner approach surface, the inner transitional surface, or the balked landing surface; should be frangible and mounted as low as possible.

(f)Any equipment or installation required for air navigation or for aircraft safety purposes that is an obstacle of operational significance in accordance with CS ADR-DSN.J.470(d), CS ADR-DSN.J.475(e), CS ADR-DSN.J.480(g), or CS ADR-DSN.J.485(e) should be frangible and mounted as low as possible.
