to initiate the aerodrome's LVP.

       (2) At a controlled aerodrome, the aerodrome operator must cooperate with ATC to ensure that LVP are fully implemented before:

(a) for approach operations — the earlier of the following:

 (i) the reported cloud ceiling falls below the precision approach CAT I decision height published in the AIP for the runway to be used;

 (ii) the visibility falls below the precision approach CAT I RVR minimum published in the AIP for the runway to be used; and

(b) for take-off operations — the reported runway visibility falls below 800m, or RVR on the relevant runway falls below 550 m.

Notes

       1. The point at which restrictions on aerodrome operations should be progressively introduced as the weather deteriorates will vary from aerodrome to aerodrome depending on local conditions. The point should relate to a specific RVR or runway visibility measurement in a worsening weather situation and should be based on the rate of weather deterioration and the amount of lead time necessary to implement extra measures.
       2. In order to continue unrestricted operations for as long as possible while weather conditions deteriorate, LVP should be designed to implement most of the ground-based measures in good time, and in certain circumstances before they are absolutely necessary. The final measures should be implemented only when the weather conditions demand it. However, there is potential for misunderstandings to occur as to the status of LVP at the aerodrome. Procedures should ensure that the potential for such misunderstandings is minimised and that there is a single point from which definitive information about the current status of LVPs can be confirmed.
       3. ATC will inform pilots that LVP are in force, but only after:
          (a) ATC has verified that all LVP measures at the aerodrome are in place; and
          (b) for an aerodrome conducting instrument approach operations with minima less than those for precision approach CAT I or with localiser-guided take-offs — procedures are in place to safeguard ILS critical and sensitive areas.

       4. ATC will normally inform the aerodrome operator when LVP measures must be implemented.
       5. LVP are specific to each aerodrome and may apply to a segment or the entire manoeuvring area as agreed to by the air traffic management service provider.
       (3) The aerodrome operator must advise ATC when all aerodrome operator preparations for initiation of LVP are complete.

       (4) At a non-controlled aerodrome, LVP must be fully implemented before a pilot performs a low-visibility departure with a runway visibility below 800 m.

       (5) For subsection (4), the aerodrome operator must advise the pilot when all aerodrome operator preparations for the initiation of the LVP that are required for low-visibility departures are complete.
