17、 28 BS EN 50512:2009EN 50512:2009 4 Introduction This European Standard contains the requirements for an Advanced Visual Docking Guidance System (A-VDGS) as it is described in the ICAO Annex 14. This standard covers the characteristics of the electrical and mechanical components. This standard inclu

18、des the software design where this affects the required system performance and safety. An A-VDGS is to be designed to achieve safe and precise guidance during the docking procedure of an aircraft. The system provides at least a display which shows information of azimuth guidance and stop information

19、. The use of an A-VDGS is in principle limited to a defined area with an opening angle and a border distance to the stop point related to the centre line. The reference point for all distances and guidance information at the aircraft is the central axis of the nose wheel. It has to be considered tha

20、t in some cases the topographical situation of an airport requires a reduced working area for an A-VDGS which will result in the area being different from the requirements stated herein. For practical use on the airport it has to be considered that the detection range can be limited due to the actua

21、l weather and visibility condition prevailing (fog, rain, snow, etc.). 1 Scope This European Standard specifies requirements of electrical and mechanical design, installation, maintenance and testing procedures for advanced visual docking guidance systems. 2 Normative references The following refere
