(b)
A preceding departing aircraft is airborne and has passed over the localizer aerial.
The LSA in front of an arriving aircraft shall not be infringed from the time it is 2NM fm the touchdown until it has completed its landing roll. The Low Visibility Taxi routes are intended to assist the pilots in determining their location on the airport during the periods of low visibility. The centerline lights on the taxiway not in use may be switched off. During Take-off in Cat II, Cat IIIA, IIIB condition the LSA in front of a departing aircraft shall not be infringed from the time that take-off clearance is issued until the aircraft has departed and passed over the localizer aerial. ATC shall initiate emergency, action, if an aircraft not seen or is not in radio contact as expected.
7.6.3. Surface Movement Control Procedures
Pilots need additional guidance and information when taxing during periods of reduced visibility. The view from the cockpit of the aircraft is very limited. Therefore taxi instructions and essential traffic information should be passes in a clear and concise manner. Taxing aircraft should be routed in accordance with the prescribed Low Visibility Routes to ensure a simple one-way traffic flow is maintained, however it may be necessary for operational reasons to sometimes route aircraft via alternative taxiways. During LVP full use should be made of intermediate Taxi holding point and selective switching of taxiway centerline lights to control traffic and provide additional visual guidance to pilots.
Surface Movement Control shall monitor the status of taxiway lights and immediately advise the aircraft under its control of any unserviceability affecting the LVP taxiways. During the period of LVP the lights on taxiways that are not being used should be switched off wherever possible. Surface Movement Control should monitor the progress of arriving aircraft as they vacate the runway after landing and ensure that they do not stop within the LSA thereby degrading ILS integrity for subsequent landing aircraft. Pilots shall report RWY vacated on RTF when the aircraft has reached the colour size to ensure that the entire aircraft is clear of the ILS sensitive area. Vehicles movement when RVR is less than 550 m should be restricted. Only operationally essential vehicle duly authorized by Apron Control should be permitted to operate. These vehicles shall remain out side the Localizer Sensitive Area (LSA). Any movement of vehicle on the maneuvering area shall be coordinated with ATC.
