LOW VISIBILITY PROCEDURES:
1.PURPOSE
The Purpose of this SOP is to set out process and procedures to ensure added safety measures during bad weather/poor visibility conditions, to ensure smooth, safe and efficient conduct of aircraft operations, by establishing:
a) Conditions for implementation of LVP.
b) Safeguarding procedure (SP) for implementation of LVP.
c) Procedure for termination of LVP
2. SCOPE
Maharishi Valmiki International Airport, Ayodhyadham, Ayodhya is certified ILS CAT I aerodrome with a prescribed landing minima of 550 m RVR for RWY 29. The DGCA CAR on All Weather Operations mandates the establishment of Low Visibility Procedures for continuing operations below RVR values of 550 m. Accordingly Low Visibility Procedures have been established at Maharishi Valmiki International Airport, Ayodhyadham, Ayodhya to enhance and ensure safety during low visibility / bad weather conditions
3. DEFINITIONS & ABBREVIATIONS DEFINITIONS:
RVR: Runway visual range (RVR)-The range over which the pilot of an aircraft on the centre line of a runway can see the runway surface markings or the lights delineating the runway or identifying its centre line.
Touchdown zone-The portion of a runway, beyond the threshold, where it is intended that landing aero planes first contact the runway.
Obstacle Free Zone: The airspace above the inner approach surface, inner transitional surface and balked landing surface and that portion of the strip bounded by these surfaces, which is not penetrated by any fixed obstacle other than of low mass and frangible mounting, required for air navigation purposes.
Safeguarding Procedures: Safeguarding Procedures (SP) are instructions for relevant airport departments and airside operators to prepare ground services and facilities for low visibility operations, in order that when LVP are implemented all SP are complete and airport is configured for Low Visibility Procedures and Low Visibility Take-offs.
