reported cloud ceiling is less than the precision approach Category I decision height published in the AIP for the runway to be used; or

(ii)          the visibility is less than the precision approach Category I RVR minimum published in the AIP for the runway to be used;

(b)         a take-off operation when the reported visibility or RVR on the runway to be used is less than 550 m.
Note When LVP are implemented, the aerodrome operator is required to complete all operator preparations relevant to LVP to commence, and confirm to ATC that these preparations are complete. See also subsection 10.17.3 of Manual of Standards (MOS) – Part 139 Aerodromes.

10.3.3.3         ATC must inform pilots that LVP are in force, but only after:

(a)         ATC has verified that LVP at the aerodrome are fully implemented; and

(b)         for an aerodrome that supports instrument approach operations with minima less than precision approach Category I — procedures are in place to safeguard the ILS critical or sensitive areas as required for the classification on the ILS and in accordance with subsection 10.3.4.6; and

(c)          for an aerodrome that supports localiser-guided take offs — procedures are in place to safeguard the localiser critical and sensitive areas as required for the classification on the ILS and in accordance with subsection 10.3.4.7.

10.3.4              Protecting ILS critical and sensitive areas

10.3.4.1         ATC must not permit a vehicle or personnel within the relevant ILS critical areas during ILS operations.

10.3.4.2         Subject to 10.3.4.3, ATC must not permit an aircraft to be within the relevant ILS critical area if:

(a)         the cloud ceiling is at, or below, 600 ft; or

(b)         the visibility is 2 000 m or less.
Notes
1. The relevant ILS critical area means either the critical area appropriate to the largest aircraft that uses the aerodrome, or the critical area appropriate to the particular size and shape of the aircraft or vehicle.
2. An aircraft taking off and passing over the relevant localiser is not taken to be penetrating the relevant localiser critical area.

10.3.4.3         Subject to 10.3.4.4, an aircraft may enter an ILS critical area:

(a)         without ATC clearance, while landing or vacating a runway after landing; or

(b)         under ATC clearance, provided:

(i)            an approaching aircraft has not passed the ILS outer marker; or

(ii)          if an outer marker is not available — an approaching aircraft is not within 4 NM of the landing runway threshold.

10.3.4.4         If an aircraft penetrates the critical area when the cloud ceiling is at, or below, 600 ft, or the visibility is 2 000 m or less, ATC must broadcast an appropriate warning to:

(a)         any approaching aircraft that have passed the ILS outer marker; or
