LOW VISIBILITY PROCEDUES
KHAJURAHO AIRPORT, KHAJURAHO (VEKO)
1 INTRODUCTION
1.1 Until the latest amendment of DGCA Civil Aviation Requirements (CAR) section 8, Series ‘C’, Part-I on All-Weather
Operations, Low visibility procedures were required at aerodromes for the purpose of ensuring safe operations during
Categories II and III approaches and/or low visibility take-offs (LVTO).
1.2 However, in latest amendment to CAR (Rev. 10), para 5.3, following provision regarding Low visibility procedures is
added. “An operator shall not conduct takeoff with RVR/visibility less than standard Category I conditions of 550m
RVR/800 m visibility unless low visibility procedures are enforced”.
1.3 This provision necessitated the need for low visibility procedures for accommodating/permitting departures in
Visibility/RVR less than 800M/550M even at such airports where there are no CAT II and CAT III operations
1.4 As per provisions of Aerodrome Design and Operations CAR and ICAO Annex 14, Runway centre line lights are
required for take-off in RVR below 400 M. Further, as per Aerodrome Design and operations CAR para 9.8.7, Surface
Movement Radar(SMR) need to be provided at an aerodrome intended for use in Runway Visual Range conditions
less than a value of 350 M
1.5 Accordingly, Low visibility Procedures have been developed for Khajuraho Airport to accommodate/permit departures
in Visibility/RVR less than 800M/550M from RWY 19 (runway served with RVR instruments). and since, there is No
SMR facility at Khajuraho Airport, these procedures will be applicable for take-off in VIS/RVR below 800M/550M but
not less than 400 M RVR.
2 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 :
(i) Conditions for implementation of LVP.
(ii) Safeguarding procedure (SP) for implementation of LVP.
(iii) Procedure for termination of LVP
3 SCOPE
Khajuraho is certified ILS CAT I aerodrome with a prescribed landing minima of 550 m RVR for RWY 19. The
DGCA CAR on All Weather Operations mandates establishment of Low Visibility Procedures for continuing departure
operations below RVR values of 550 m but not less than 400m RVR. Accordingly Low Visibility Procedures have been
established at Khajuraho Airport to enhance and ensure safety during low visibility / bad weather conditions.
4. DEFINITIONS AND 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 landing aeroplanes 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.
