Under what condition can the minimum clearance distance on a de-icing/anti-icing pad be reduced?

The minimum clearance distance can be reduced where the de-icing/anti-icing facility is located in a non-movement area.

Does the guidance specify a required number of mobile de-icing/anti-icing vehicles that must be able to operate simultaneously on a single pad?

The guidance states that the separation criteria should take into account the need for individual pads to provide sufficient manoeuvring area to allow simultaneous treatment by two or more mobile de-icing/anti-icing vehicles, but it does not specify a fixed number.

Q: What is the purpose of providing sufficient non-overlapping space between adjacent de-icing pads?

The purpose is to allow for a vehicle safety zone between adjacent de-icing pads and for other de-icing/anti-icing pads.

ED Decision 2022/006/R

(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.
