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 includes 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.
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 that 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 actual 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.

3.7
detection range
the distance within which the A-VDGS is able to detect an aircraft
