GM1 ADR-DSN.G.400 Clearance distances on a de-icing/anti-icing pad

(a)The separation criteria should take into account the need for individual de-icing/anti-icing pads to provide sufficient manoeuvring area around the aircraft to allow simultaneous treatment by two or more mobile de-icing/anti-icing vehicles and sufficient non-overlapping space for a vehicle safety zone between adjacent de-icing pads and for other de-icing/anti-icing pads.

(b)The minimum clearance distance of 3.8 m is necessary for the movement of de-icing/anti-icing vehicles round the aircraft.

(c)Where the de-icing/anti-icing facility is located in a non-movement area, the minimum clearance distance can be reduced.
