Project

Reference ENV 50235:1997
Title Aeronautical ground lighting electrical installation - Signs: Equipment specifications and tests
Project Number 7222
Abstract/Scope This standard covers signs installed in the movement area to provide pilots and vehicle operators with information. The Standard is applicable to signs with built-in illumination arrangements using tungsten filament, tubular flourescent and other discharge lamps on supply voltages not exceeding 1000 V. The standard shall not apply to non-illuminated signs or signs illuminated by external light sources. The object is to provide design and construction specifications for the signs that are considered necessary to meet the operational standards adopted by ICAO and to cover all aspects of safety (electrical, thermal and mechanical). The signs may be energised from parallel power supply or by connection to a constant current series circuit used for taxiway or runway lighting systems.
