NOTE:
a) If the intensity of any lights has reduced more than 50 % of its minimum required level, the light shall be considered
unserviceable.
b) Engg-E shall ensure the above serviceability requirements for runway lighting system before implementation of the LVP.
Any non-compliance shall immediately be reported to ATC and Apron Control.
c) UPS can supply power for a period of maximum 30 minutes.
6. SAFEGUARDING PROCEDURES
Safeguarding Procedures (SP) are instructions for airport departments, Airline operators, ground handling agents and other
agencies working in the airside to prepare ground services and facilities for low visibility operations in order that LVP are
|
implemented after all Safeguarding Procedures (SP) are completed.
Duty Officer Tower/Tower Supervisor will initiate and co-coordinate with all the concerned agencies for completion of
safeguarding procedures before implementation of Low Visibility Procedures.
6.1 Safeguarding Procedures shall be initiated when:
The Visibility/RVR is less than 1200m and the forecast is to deteriorate to 800m or less.
6.2 Safeguarding procedures include:
a) Runway inspection shall be carried out by the Apron Controller on duty along with electrical engineering officials before
implementation of LVP.
b) Positioning of one CFT each at the two predetermined positions (ATC approach road outside the Runway strip and near
Fire Station).
c) Stopping of all maintenance works on the manoeuvring area as well as removal of all men and mobile equipment from the
said area including RWY strip.
d) Safeguarding the Runway from incursion via various access road to the runway. This may be achieved by removing all
non-essential vehicles from the operational area and/or by temporarily displaying “LVP - Low Visibility Procedure in
operation” signs at roads leading to the Runways, essential Taxiways and apron.
e) The identified points for displaying the sign boards are;
i) On perimeter road holding position Hill road.
ii) On perimeter road holding position Isolation Bay/ TWY D
iii) On perimeter road holding position GP 10 (west side)
