RESPONSIBILITY |
4.1 |
Condition for Safeguarding Procedures |
At Maharishi Valmiki International Airport, Ayodhyadham, Ayodhya Safeguarding Procedures shall be initiated when:a) The Visibility/RVR is less than 1200 m and visibility/RVR is forecast to deteriorate to 800m or less; and/orb) The cloud ceiling is 400 ft. and forecast to fall to 200 ft. or less. |
|
4.2 |
Safeguarding Procedures (SP) |
Safeguarding Procedures are the necessary actions to prepare the airport for Low Visibility Procedures. They include:a) Carry out Runway, Taxiway, Road Holding, emergency access road and Apron inspection to ensure serviceability of visual aids and Ground Lights.b) Stop all maintenance works on the manoeuvring area and vacate all men, Material and equipment from the manoeuvring area.c) Termination of all work in progress in the localizer and glide path sensitive area.d) Removal of all equipment/material from localizer and glide path sensitive area.e) Restrictions on the movement of vehicles on the manoeuvring area and aprons. Limit the number of vehicles in the manoeuvring area to bare minimum. To meet any inescapable operational needs, vehicles may be escorted by Follow Me under intimation to ATC.f) Barricade provided at road holding point of service road leading to runway and other manoeuvring area is in closed condition except fire station approach road to runway. If traffic lights are provided at road holding point the same should be in ON condition.g) Ensuring availability of secondary power supply for changeover, with switchover time of maximum 1 second for RWY Edge, RWY End and Threshold lights supported by UPS.h) Initiate action for Manual RVR in coordination with IMD, if RVR equipment is unserviceable. |

i) Ops In-charge will co-coordinate with all the concerned agencies for implementation of Low Visibility Procedures.j) Ops In-charge will inspect Movement area, AGL System and Associated Roads with all the concerned HOD as per Check ListNote-1: RWY Edge, Threshold lights and RWY End lights may continue to operate on main power supply during safeguarding Procedures. Whenever LVP is to be implemented the RWY Edge, Threshold lights and RWY End lights shall be put on Standby Power Supply (DG set or UPS). This operation needs to be completed before LVP is implemented.Note-2: As UPS is available at Maharishi Valmiki International Airport, Ayodhyadham, Ayodhya capable of maintaining the required AGL system with one second of Switchover time, the main supply can continue to be the primary source of supply, and the Generator Supply can be kept as Standby Power supply. In case UPS is unserviceable, Generator supply shall be the primary source of power supply and Main power supply shall act as standby power supply.) |

4.3 |
Implementation of SP |
When meteorological conditions meet the criteria for initiation of SP as stipulated in Sl. No 4.1, the duty officer tower will inform Ops In-charge. Ops In-charge will coordinate with IC Electrical, Civil, Fire and MT.NOTE: Action to be taken by various agencies is attached as Annexure 1.Ops Inimplementation of SP check list must be completed.When all the concerned agencies have completed their necessary actions, they shall report to DUTY OFFICER TOWER (ATC) that their Safeguarding Procedure (SP) is completed, and the airport is safeguarded for LVP operations. |

Condition for Low Visibility Procedures |
Low Visibility Procedures shall be implemented when -a) Visibility is less than 800 m; and/or Cloud ceiling is less than 200 ft.; ANDb) Safeguarding Procedures (SP) have been completed, and the airport is safeguarded. |
|
4.5 |
Low Visibility Procedures (LVP |
a) Low Visibility Procedures are the actions to ensure the safe operation of aircraft during periods of reduced visibility or low cloud base.b) LVP shall only be implemented when Safeguarding Procedures (SP) has been completed, and the airport is configured for low visibility operations.(Note: Though LVP is implemented when RVR is less than 800m, ILS CAT I operation will continue till Visibility/RVR is not less than 550m) |

4.6 |
Implementation ofLVP |
When meteorological conditions meet the criteria for LVP as stipulated in Sl. No. 4.4Duty Officer Tower (ATC) implements Low Visibility Procedure, and the following action shall be followed:a) ATC shall declare LVP in force, and intimate In-charge- Airside Operations / ARFF. This information will also be included in the DATISb) ARFF shall ensure positioning of 1 CFT at the predetermined position Grid Location C4, immediately on implementation of LVP.c) In-charge Airside Operations on receiving the information shall inform concerned stakeholders (ARFF, MET, E&M, CSO & Airlines/GHA) of enforcement of LVP.d) All maintenance work on the apron shall be stopped. However, any maintenance work of urgent nature may be carried out under strict monitoring of Follow Me in coordination with ATC.e) Records of all vehicles operating on the manoeuvring area during LVP shall be maintained by In-charge- Airside Operations and the record be made available to ATC.f) In-charge- Airside Operations shall in coordination with ATC, implement Mandatory Follow Me’ service for all aircraft on apron, if the visibility conditions so demand.g) ATC shall permit only one pushback at a time on apron and one aircraft on the manoeuvring area.h) No towing of aircraft shall be permitted during LVP. However, in case of urgent requirement, towing may be permitted under mandatory ‘Follow Me’ guidance.i) High Power Engine Ground Run (HPEGR) will not be permitted during LVP. If any HPEGR is already in progress, aircraft will be advised to stop engine run and proceed to allocated stand |

j) If RVR equipment is unserviceable, manual RVR shall be obtained and provided for all departing aircraft.k) Suspend operations if RVR drops below 400 m.l) The presence of a Met Officer shall be ensured in ATC Tower during the time of LVP for assisting the ATC Controller with updated met reports.In-charge, Airside Operations shall be responsible for carrying out the following actions:a) Carry out inspection of manoeuvring and movement areas as part of Safeguarding Procedures.b) Coordinate with engineering departments to ensure availability of backup power system before implementation of LVP.c) Coordinate with ATC and IMD for manual RVR, if the RVR equipment is reported to be unserviceable.d) Ensure that the Safeguarding Procedures are completed prior to implementation of LVP and report the same to ATC.e) Strictly restrict/regulate vehicular traffic on the manoeuvring area. Record of all vehicles operating on the manoeuvring area during LVP shall be maintained and the record be made available to ATC.f) Stop all works within the manoeuvring area.g) Report any unserviceability of AGL which is essential for the implementation of LVP (RWY edge lights, RWY end lights and RWY threshold lights) and advise ATC not to implement LVP or ifalready in force, advise on termination.h) Ensure that Runway lights are inspected every 2 hours after implementation of LVP during its continuance. |

4.7 |
TERMINATION OF LVP |
a) When visibility/RVR improves to 800 m or more and/or cloud ceiling is 200 feet or higher and upward trend is forecasted by the Met Officer.b) ATC shall inform In-charge, Airside Operations regarding the termination of LVP He shall inform all concerned departments about termination of LVP.c) If SP are initiated and Low Visibility Procedures are not subsequently implemented and the visibility/RVR improves and is more than 1200 m and/or the cloud ceiling is 400 ft. or higher and both are forecast to remain above the required SP criteria, ATC may cancel SP. |
