4.3 Unserviceability of Aeronautical Ground Lights/Equipment after Implementation of LVP:4.3.1 If any light/equipment listed in Section 4.1 becomes unserviceable or fails to meet the standard as envisaged in Table 1during LVP, TWR/SMC shall inform the aircraft accordingly, suspend LVP and information to that effect included inthe ATIS broadcast.5. SAFEGUARDING PROCEDURES5.1 These procedures ensure that ground services and facilities are prepared for low visibility operations beforeimplementing LVP. Duty Officer Tower AAI, in coordination with DM Operations CIAL, initiates safeguardingprocedures based on RVR status and MET department lookout.5.2 Safeguarding Procedures Initiation:• Visibility/RVR less than 1200m and forecast to deteriorate to 800m/550m or less. |
• Cloud ceiling less than 400ft and forecast to fall to 200ft or less.5.3 Safeguarding Procedures Include:• Positioning 1 CFT each for RWY 09 and 27.• Stopping maintenance works on the manoeuvring area and associated strip areas.• Inspecting Aeronautical ground lights during the hour preceding LVP implementation and before departuresduring LVP.• Ensuring secondary power supply availability for a maximum one-second changeover time for RWY Edge andEnd lights supported by UPS/DG Set.6. LOW VISIBILITY PROCEDURES6.1 Implementation:6.1.1 The Duty MET Officer informs the Tower Supervisor/Duty Officer Tower when visibility/RVR reduces to 800m/550mor below and/or cloud ceiling is 200ft or below. ATCO coordinates with DM Operations and ARFF to confirmcompletion of safeguarding procedures. Once confirmed, the Tower Supervisor/Duty Officer Tower implementsLVP with prior WSO approval.Table 2:RVR/Visibility for Take-off (Commercial Transport Aeroplanes) |

Note 1 - The TDZ RVR/VIS may be assessed by the pilot.Note 2 - Adequate Visual reference means, that a pilot is able to continuously identify the take-off surface and maintaindirectional control.Note 3 - For night operations at least runway edge lights or centre line lights and runway end lights are available.6.2 ACTION BY VARIOUS UNITS DURING LVP:6.2.1 MET Office:• Issue “Outlook for Low Visibility” when RVR is less than 1200m or visibility is forecast to deteriorate to 800m or less.• Ensure Transmissometer serviceability and provide direct reading of TDZ RVR observations.• Deploy manpower for manual RVR if Transmissometer is unserviceable or if LVTO is to be conducted on a runwaywithout a Transmissometer.• Provide Leader service to obtain manual RVR and inform Tower Supervisor/Duty Officer Tower of any visibility/RVRchanges.6.2.2 TWR/SMC Controller - ATC:• Implement LVP with WSO approval.• Stop all ground runs on the manoeuvring area except idle power run-up on stands after coordinating with DM OperationsCIAL. |
• Allow only vehicles with serviceable R/T on the manoeuvring area; vehicles without R/T may operate if escorted by a Follow Me Vehicle.• Permit departures only from the beginning of the Runway-In-Use.• Coordinate safeguarding procedures and declare LVP in place when visibility/ RVR goes below 800m/550m.• Stop flight operations when RVR falls below 350m and inform WSO.6.2.2.1 Taxi and Take-off Instructions:• Allow only one push-back/start-up at a time per apron, unless their taxi tracks do not conflict.• Confirm the positions of preceding aircraft for consecutive taxiing departures and clear succeeding traffic accordingly.• Departing aircraft at the holding point may enter the runway only if no landing aircraft is within 8NM from touchdown.• Check airline operator/aircraft approval for departure in RVR less than 400 m before push-back.6.2.3 DM Operations CIAL:• Conduct runway inspection to ensure serviceability of RWY Edge, Centreline, and End lights.• Inspect AGL before departures during LVP and inform ATC of any non-compliance.6.2.4 APRON Control / AOCC:• Ensure towing of aircraft under escort of Follow Me vehicles.• Provide Follow Me service to non-scheduled aircraft and restrict the number of vehicles operating on the manoeuvringarea.• Do not permit high power run-up of aircraft in the movement area.• Follow safety protocols for vehicle movement on the apron.6.2.5 Duty Manager ARFF:• Position 1 CFT each for RWY 09 and 27 after obtaining permission from ATC.• Inspect runway and taxiways for compliance.6.2.6 In-Charge - Electrical:• Continuously monitor main and standby power supply to ensure change over time of maximum one second for criticalAGL during LVP.6.2.7 Airlines:• Pilots must ensure RVR is within minima for LVTO while requesting push- back/start-up.6.2.8 Ground Handling Agencies:• Activate LVP protocols and coordinate with DM AOCC.• Enhance communication and coordination, ensure serviceability of obstruction lights on equipment, minimize groundmovement, ensure availability of retroreflective markings on equipment, ensure staff wear PPE, strictly adhere to pushbackand towing procedures, pre-arrival and departure coordination, conduct regular safety briefings, follow rigorous trainingand adherence to protocols and prepare for emergencies.6.2.9 Fuelling & Catering Agencies:• Follow strict safety protocols, use appropriate lighting, reduce speed and manoeuvre cautiously, maintain enhancedcommunication, adhere strictly to procedures, and conduct safety checks.7. TERMINATION OF LOW VISIBILITY PROCEDURES7.1 When visibility/RVR improves to 800m. |
