LVP'S (V2)

• Runway 25 is equipped for Cat 3b operations. The following list gives guidance on the systems required to carry out Cat 2/3 approaches. The list is not exhaustive.
  
  1. IRVR (manual RVR not permitted for Cat 2/3 approaches)
  
  2. Standby generators. If the unavailability of an alternate power supply exceeds a period of 2 hours, approaches should be restricted to non-precision instrument status and take-offs limited to visual ranges greater than 400m
  
  3. Cat 2/3 ILS
  
  4. Stopbars, taxiway guidance, centreline lighting.

• FLOW RATES
  
  When IRVR is less than 400m, unless aircraft manoeuvring are continuously visible to ADC, or aircraft are continuously visible to each other, ADC must restrict arrival and departures as follows:
  
  1. No more than one departure is permitted to taxi to the A2 hold
  
  2. Subsequent departures must not be taxied until the A2 stopbar can be selected
  
  3. Approach should sequence arrivals with 15nm spacing
  
  4. Declared movement rate (in and out) is 10 per hour.

• VISIBILITY CONDITIONS:
  
  VISIBILITY ONE : Visual surveillance
  
  PREPARATION PHASE : Met visibility is 2000m or less / cloud base is 300ft or less / VCFG is reported
  
  LVP's : IRVR 800m or less / cloud ceiling less than 200ft

PREP PHASE

• ATC will prepare for LVP's whenever any of the following conditions occur: 1. The reported Met visibility is 2000m or less 2. The cloud base is 300ft or less 3. Fog in the vicinity (VCFG) is reported.

• Inform BIA Operations via the direct line to "Prepare for LVP's"
