## GM1 ADR-DSN.E.365 Clearance distances on aircraft stands

(a) Reduced separation at the gate is possible where azimuth guidance by a visual docking guidance system is provided, in combination with additional mitigation measures, such as:

(1) good condition of [marking](https://avioverse.aero/glossary/easa/marking) and signage;

(2) maintenance of visual docking systems.

(b) On [aircraft](https://avioverse.aero/glossary/easa/aircraft) stands, where reduced clearance distances are applied:

(1) Guidance by a visual docking guidance system should be provided.

(2) All objects for which reduced clearances apply should be properly marked or lighted (see Chapter Q [Visual Aids](https://avioverse.aero/glossary/easa/visual-aids) for Denoting Obstacles).

(3) Aircraft stands where reduced clearance distances apply should be identified and the information published in the AIP.

(4) For code letters D, E or F, an [aircraft stand](https://avioverse.aero/glossary/easa/aircraft-stand) equipped with a visual docking guidance system the minimum clearance of 4.5 metres may be applied between an aircraft entering or exiting the stand and any adjacent building, aircraft on another stand or other objects.

(5) For code letter C an aircraft stand equipped with a visual docking guidance system the minimum clearance of 3 metres may be applied between an aircraft entering or exiting the stand and any adjacent building, aircraft on another stand or other objects if a safety assessment indicates that such reduction would not affect the safety of operations of aircraft.

(c) Any aircraft passing behind an aircraft parked on an aircraft stand should keep the required clearance distances defined in Table D-1.
