![]() ![]() Since runways are lit in a predictable, standard way if you are on approach to an airport in a well lit city it can help to split the airport out from all the roads and highways when looking for it in the terminal area. At night, if the tower closes they may simply leave the lights on as there is no way to remote key them.Īt night, even in good weather (or especially in good weather) lights can help identify an airport from quite a distance. Video Timeline: landing 1 - 0:56 landing 2 - 3:55 landing 3 - 5:32 landing 4 - 7:05 PCL or Pilot Controlled Lighting is a system that allows pilots to control the lighting. This is only applicable if the tower is in operation. Larger towered airports may keep some lights on and allow you to request others be turned on or off. If you turn them on to far out and forget about it they may shut off on short final. They are typically on a 10 or 15 minute timer. Here in the states smaller non-towered airports often have lights that are always off, a pilot can turn them on by keying the mic button on their radio 3 or 5 times. There are lots of variables here but different airports handle this differently. The lights may also not always be on, it may simply be that you happen to drive past them when they commonly are on. In some cases the lights are actually part of the instrument system and the regulations may dictate that if the ILS is on so are the lights. In that case its simple courtesy to leave them on. There are plenty of cases where they may not be, (here in the US GA traffic is one), emergencies, diversion, aircraft not operating on a flight plan etc. You mention that the airport does not have a whole lot of arrivals but you would only be able to progressively turn them on and off if all the arrivals were planned. Typically when the visibility drops below a certain level airports will turn their lights on. Pilot Controlled Lighting: On runways with both approach lighting and runway lighting (runway edge lights, taxiway lights, etc.) Runways without approach. I deduced that runway lights are kept always on as soon as the day This is very similar to a so called Pilot-controlled lighting system or PCL but I would like to build and use at home, not for industrial or commercial use and also I would like to use the latest technology to build it. ![]() The answer to the question lies in your statements Hi, I am starting on a project, and I would like to get some help to start with this or get some tips on how to start and where. ![]()
