Modern lsystem of lights
During night-time all aircraft movements within Gdansk Lech Walesa Airport are facilitated by a hi-tech Finnish IDMAN OY manufactured navigation light aid system. It is remotely controlled from the control tower and is backed-up by a reserve power source, in line with ICAO requirements.
A geometric ALPHA-ATA set up is used on the primary direction runway. It is 900 metres long with a crossbar situated 300 metres from the threshold. At night, this set up resembles a luminescent cross made up of 123 lights and a flash line and 30 flashing lights emmitting regular signals.
The beginning and end of the runway are marked with respectively green and red threshold lights as well as wing bars. After landing a pilot follows ninety two 200-Watt white/yellow and white/white lights. One of the paths - Alfa4, Alfa5, Bravo or Charlie, indicates a taxi holding positions along the taxiway. It is illuminated by 45-Watt blue edge lights fixed within the surface.
In 2004, the work on the installation of the PAPI lights on the ancillary runway no. 11 has started, to allow for instrument approach from both directions of the runway.
Depending on weather conditions and visibility, control officers select one of the five pre-programmed levels of light intensity: 1, 3, 10, 30 or 100%.
The efficiency of the lighting system is ensured by two main and one reserve cables, two transformer stations and two power-generators.
Daylight marking system
Apart from the ancillary navigation lights, controlled from the control tower, Gdansk Lech Walesa Airport has also a daylight marking system:
RWY: threshold, touchdown zone, centre line, fixed distance, RWY designators, side strip;
TWY: ocentre line, taxi holding positions, side strip;
Runway surface friction calibration is ensured by a state-of-the-art G4 computer-aided AIRPORT SURFACE FRICTION TESTER.
