18、0:2008EN 50490:2008 4 Introduction Aeronautical Ground Lighting (AGL) at an aerodrome provides the pilots of aircraft and drivers of vehicles moving on the aerodrome surface, with guidance information. Selective switching and individual lamp monitoring is one way of controlling the AGL to achieve th
19、is. 1 Scope This European Standard is intended to give general minimum frame requirements for units that are independent of the technology used for switching and/or monitoring of individual or group of lamps in an AGL series circuit. This European Standard applies to the units that are directly elec
20、trically connected to the primary or secondary side of an AGL series circuit and are needed to provide the selective switching and/or monitoring of lamps, does not cover communication protocols and application procedures, does not treat system aspects that influence the AGL operation. NOTE These uni
21、ts may be used forming part of either a SMGCS or A-SMGCS to guide and/or control the surface movement of aircraft by means of visual aids. 2 Normative references The following referenced documents are indispensable for the application of this document.
