SECTION 2: CHAPTER 2 AERODROME LIGHTING AIDS Flashcards
Operating instructions for individual lighting systems and the intensity setting to be used in different weather conditions, by day and night, shall be detailed in MATS Part 2.
Guidance on typical luminous intensity settings can be found in CAP 168 Chapter 6. These settings may be varied at the controller’s discretion or at the request of a pilot, provided that other aircraft will not be adversely affected.
At certain aerodromes, where RVR reference lights are in use, the runway lighting may be temporarily switched off if this will facilitate an accurate count of the reference lights for RVR purposes. This shall not be done either:
(1) while an aircraft is taking-off;
(2) after an aircraft has reported completing a final procedure turn; or
(3) after an aircraft has reached 5 miles from touchdown on a radar approach
Aerodrome lighting appropriate to the runway a pilot is to use shall be displayed for an appropriate period of time as specified in MATS Part 2, before any ETA and after any ATD as follows:
(1) By day: High intensity systems, where installed on the runway to be used, whenever the visibility is less than 5 km and/or the cloud base is less than 700 feet;
(2) By night: Irrespective of weather conditions
When the ATD of an aircraft is such that lighting will be displayed after aerodrome closing time, the pilot concerned should be warned that the aerodrome will close at the normal published time,
and advised that lighting only will be displayed after his departure. The availability of other aerodrome services, e.g. the Aerodrome Fire Service, approach aids, etc., during this period should also be clearly stated. Availability of aerodrome services outside of published hours is detailed in Section 2 Chapter 1.
Obstruction lighting, hazard beacons and aerodrome light beacons shall be displayed
at night during the published hours of watch. Hazard beacons shall also be displayed by day whenever the visibility is less than 3500 metres.
In addition to the display periods shown above, lighting may be displayed at
any other time if it is requested by the parent ACC, required by MATS Part 2 or considered necessary by the controller
