GM1 ADR-DSN.L.595 Apron safety lines ED Decision 2016/027/R (a) Ground equipment and vehicles should be kept outside predetermined limits when aircraft are manoeuvring or when the equipment is left unattended. (b) Safety lines are required on an apron to mark the limits of parking areas for ground equipment, apron service roads and passengers’ paths, etc. These lines are narrower and of a different colour to differentiate them from the guidelines used for aircraft. (1) Wing tip clearance lines. These lines should delineate the safety zone clear of the path of the critical aeroplane wing tip. The line should be drawn at appropriate distance outside the normal path of the wing tip of the critical aeroplane; (2) Equipment limit lines. These lines are used to indicate the limits of areas which are intended for parking vehicles and aircraft servicing equipment when they are not in use. (c) Several methods may be used to identify which side of a safety line is safe for storage of such vehicles and equipment: (1) Spurs or an additional line (a discontinuous line of the same colour or a continuous line of a different conspicuous colour) may be provided on one side of the safety line. The side on which such spurs or an additional line is located is considered safe for parking vehicles and equipment; (2) The words ‘Equipment Limit’ may be painted on the side used by ground equipment and readable from that side; (3) Passenger path lines. These lines are used to indicate to passengers and escorting personnel the route that needs to be followed, when walking on the apron, in order to be clear of hazards. A pair of lines with zebra hatching between them may be used.
