1.1 Aims and Objectives 1 SECTION 1 - Low Visibility Procedures (LVP s) ADR.OPS.B.045 Low visibility operations states The aerodrome operator shall ensure that means and procedures are established and implemented for providing safe conditions for aerodrome operations in low visibility conditions. Low visibility procedures shall require prior approval by the Competent Authority. To provide a safe environment for operation of aircraft in conditions when surface visibility is reduced below 1500m. A serious constraint during these conditions is the inability of the ATC aerodrome controller to see the manoeuvring area. During low visibility conditions, the manoeuvring area shall therefore be guarded against unauthorised vehicle movements. The implementation of LVP s by the ATC Aerodrome Controller shall be a two-phase procedure, LVP1 (Safeguarding) and LVP2 being the enforcement of LVPs. 1.2 Background LVPs are designed to protect: The active runway from incursion by aircraft, vehicles or persons. The ILS Localiser Sensitive Area from unauthorised entry The Obstacle Free Zone During LVPs, vehicle movements on the manoeuvring area will only be permitted on receipt of an ATC clearance for operationally essential reasons e.g. Emergency services, AOU Inspections, Bird Scaring, and AGL inspections etc. All personnel trained in Low visibility shall be recorded and audited as part of the Airport Company internal audit system. RFFS personnel shall be responsible for the provision of driver training during LVP conditions. All vehicles on the manoeuvring area during LVP s shall be equipped with: Radio communications to maintain contact with ATC at all times; A current map of the aerodrome (Airfield Map) LVP s are subject to the ATC internal audit system. It is important that all staff operating airside should be aware of the requirement for LVPs and of the implications of Category (CAT) II/III ILS operations. In order to safeguard these procedures it is necessary to adopt certain practices for staff working airside. LBA has for many years operated in low visibility with the involvement of all apron users without any major associated incident occurring on the apron during fog conditions. A general culture and understanding is already in place. However, in view of the risks of operating in more Page 6 of 9
demanding weather conditions additional detailed procedures are required to ensure that safety is maintained as part of a Safety Management System (SMS). 1.3 Definitions Category I, II and III All criteria and minima for Category I, II and III can be found in ICAO Annex 10 V1 and CAP 670 Part C Section 2. Further guidance can be found in MATS PT II,, Chapter 15 All Weather Operations 1.4 Category II/III requirements Before an operator is able to undertake a Category II/III approach and landing a number of requirements must be met: The aircraft systems must be serviceable to Category II/III standards. The weather conditions must meet the operational requirements for the particular type of aircraft being used. The aircrews must be trained and currently rated to the standard of procedures being used. The aerodrome ground lighting must be serviceable to Category II/III tolerances. The aerodrome ILS must be serviceable to Category II/III tolerances. 1.5 Aircraft equipped with Enhanced Vision Systems Runway 14 suitable for EVS operations in accordance with ILS03 EU OPS. Runway 32 suitable for EVS operations in accordance with ILS03 EU OPS. 1.6 Lower than Standard Category I Runway 14 suitable for Lower Than Standard Category I operations in accordance with ILS03 EU OPS. Runway 14 suitable for Lower Than Standard Category I operations to a minimum RVR of 450m with runway centreline lights unserviceable. Runway 32 suitable for Lower Than Standard Category I operations to a minimum RVR of 400m with either runway centreline lights or touchdown zone lights unserviceable. Runway 32 suitable for Lower Than Standard Category I operations to a minimum RVR of 450m with both centreline lights and touchdown zone lights unserviceable. 1.7 Other than Standard Category II Runway 32 suitable for Other Than Standard Category II operations in accordance with ILS03 EU OPS. Runway 32 suitable for Other Than Standard Category II operations to a minimum RVR of 450m with both centreline lights and touchdown zone lights unserviceable. Note: Other Than Standard Category II operations do not required Supplementary Lighting. Page 7 of 9
The RVR s specified for all procedures are the minimum available. The actual RVR s that operators may use may be higher depending on operator limitations. 1.8 LVP Aerodrome Safeguarding It is a requirement that to safeguard operations in low visibility, special procedures are implemented by Air Traffic Control (ATC) when LVPs are initiated. ATC and/or AOU will authorise the switching on of the LVP warning signs located at strategic points on the airfield and to perform the standard LVP check, which may have to be carried out after LVP s have been announced. An AOU LVP check includes: - Multiflight West apron Gate 1 (Pedestrian gate by security barrier) Multiflight Central apron Gate 4A (Vehicle gate) Multiflight Central apron Gate 4B (associated pedestrian gate) Multiflight Central apron Gate 5 (Pedestrian gate to Multiflight east building) Multiflight east apron Gate 6 (Vehicle gate) Multiflight east apron Gate 7 (Pedestrian gate) Vehicle Hold Point 1 (VH1) LCC traffic lights LVP Signs (Stands 19, 17, 8, 7 and Fire Station) Close Fuel Farm B Gates that lead onto Alpha Taxiway. It is essential that in LVPs all staff working airside are aware of the safety implications and proceed with extreme caution at all times. Aircraft will be moving to/from stands in restricted visibility and reaction time and vehicle-stopping time is increased. Vigilance must be increased and a careful look out must be maintained. In LVPs the following procedures will apply: Vehicle movements must whenever possible route via the airside road or if not able to do so via the inner edge of the apron nearest to the terminal building. Vehicle operating and lighting requirements must be in accordance with AOP 15. Only essential vehicle movements associated with aircraft operations are permitted. The apron road speed limit is reduced to 5 mph. Access to parked aircraft must be made directly from the airside road at right angles to the aircraft stand. The access gate to Fuel compound B must be closed to prevent an Alpha taxiway incursion. The movement of passengers on the apron must be very carefully controlled at all times. Airline or Handling agent s ground staff must ensure that safety of passengers is paramount. If the visibility is such that adequate control cannot be maintained, then passengers must be transferred by bus to/from the gates. If necessary, additional staff should be utilised to guarantee the safety of passengers. Page 8 of 9
All apron users must be aware of the potential dangers of ramp activities in LVPs. In low visibility there is a risk of disorientation and drivers should be experienced in low visibility operations and trained accordingly. Until a supervisor considers a driver is sufficiently experienced in such conditions, a person who is competent to operate in low visibility should always accompany the less experienced driver. The Airport Company will monitor activities in LVPs and should any operator be concerned about operating in LVPs or have any particular concerns they should discuss this with their supervisor who will bring it to the attention of the AOU. 1.9 LVP Procedures for ATC These are detailed in MATS PT II,, Chapter 15 All Weather Operations 1.10 Cancellation of LVP s The cancellation of LVPs is the responsibility of the ATC Aerodrome Controller actions as per the checklist referred to in MATS PT II,, Chapter 15 1.11 Records The Duty ATCO shall record the time of initiation and cessation of LVP s in the ATC Watch Log together with all associated actions. The Airport Operator is legally required to provide the CAA with information concerning all aircraft landings and take-offs made during RVRs of 1500m or less. This can be obtained via the ATC Chroma system. 1.12 Follow Me Procedures In order to provide assistance to aircraft taxying during LVP conditions, a Follow Me is available. AOU will provide this service and will only be given at the request of a pilot for assistance. 1.12.1 Arrivals ATC will contact AOU by R/T and pass the Type of Aircraft, Apron Entry Point and Stand Number. 1.12.2 Departures If requested by the Pilot, ATC will request the Follow Me vehicle through AOU. 1.13 RFFS Search Procedures For training purposes it is a requirement that the RFFS department conduct LVP Search Procedures during actual LVP conditions. These will be conducted during darkness when there are no ATC movements and the Crew Commander will liaise with ATC before the start of the exercise. 1.14 Assessment of Runway Visual Range (RVR) 1.14.1 Runway Visual Range (Human Observation Method) The measurement of RVR s by the human observation method is unavailable at LBA. In the event that an IRVR measurement is not available, the pilot should be passed the met visibility and advised that RVR is not available. Page 9 of 9
