The aerodrome (landing ground) lighting system is a set of obstacle lights (signalling lamps) placed in a certain scheme at an aerodrome or landing ground and designed to provide take-off, final approach, landing and taxiing of aircrafts.
The main task of the lighting facilities is to provide a discernable contact of flight crews with the surface of the runway (landing ground) in the approach, landing, taxiing and takeoff of aircraft in the dark and at dusk, as well as in conditions of limited or poor visibility at any time of day. Lighting facilities are subdivided into easily distinguishable and those located according to the purpose and in a certain regulatory sequence in the area of the aerodrome, heliport, heliport deck or landing ground of the group of lights, aerodrome signs.
The structure of lighting systems includes:
Lighting facilities (aboveground and deepened lights, active and passive aerodrome signs, wind socks);
Power supply equipment: cable network, backup power units, switchgears, transformers, power and control boards, uninterruptible power supply boards - UPSB, thyristor brightness controllers - TBC;
Remote control equipment (remote control complex - RCC - for controlling air and ground traffic of aircrafts through the lights from one or several control towers and from the shift engineer's work-bench);
APPLICATION OF MODERN LIGHTING SYSTEMS:
High Intensity Lighting System (HIL) is a system of aerodrome lights in which the landing lights have a candlepower of at least 10,000 Cd (150/200 W lamps).
Low Intensity Lighting System (LIL) is a system of aerodrome lights in which the landing lights have a candlepower of not more than 10,000 Cd (lamps up to 100 W).
