• (a) vehicles and other mobile obstacles on the movement area shall be marked so as to be visible to pilots during aircraft operations;

• (b) where the heliport is used at night or in conditions of low visibility, vehicles and other mobile obstacles on the manoeuvring area shall be lighted;

• (c) elevated aeronautical ground lights on the movement area shall be marked so as to be conspicuous by day; and

• (d) in accordance with the applicable heliport standard, a fixed obstacle located on the safety area shall be

  • (i) marked, and

  • (ii) where the heliport is certified to be available for use at night, lighted.

(2) The operator of a heliport shall mark and, if the heliport is certified to be available for use at night, light fixed obstacles located within the area identified in the applicable heliport standard, except where the obstacle is

• (a) shielded by another fixed obstacle that is marked in accordance with Standard 621;

• (b) conspicuous by reason of its shape, dimensions or colour;
