# GM1 ADR-DSN.G.385 Size of de-icing/anti-icing pads

Certification Specifications and Guidance Material for Aerodrome Design (CS-ADR-DSN) — Issue 7 · Regulation (EU) No 139/2014 · EAR revision 13 Mar 2026

GM Guidance material

## GM1 ADR-DSN.G.385 Size of de-icing/anti-icing pads

(a) It is recommended that the [aerodrome](https://avioverse.aero/glossary/easa/aerodrome) have facilities with a de-icing/anti-icing capability equivalent to the maximum peak hour departure rate that can be managed by the ATC units during de-icing/anti-icing operations. Additional guidance is given in ICAO Doc 9640, Manual of [aircraft](https://avioverse.aero/glossary/easa/aircraft) ground de-icing/anti-icing operations, paragraph 8.3.

(b) The number of de-icing/anti-icing pads required should be determined based on the meteorological conditions, the type of aeroplanes to be treated, the method of application of de-icing/anti-icing fluid, the type and capacity of the dispensing equipment used, and the volume of traffic and departure flow rates.

(c) An [aeroplane](https://avioverse.aero/glossary/easa/aeroplane) [de-icing/anti-icing pad](https://avioverse.aero/glossary/easa/de-icinganti-icing-pad) consists of:

(1) an inner area for parking of an aeroplane to be treated; and

(2) an outer area for [movement](https://avioverse.aero/glossary/easa/movement) of two or more mobile de-icing/anti-icing equipment.

(d) Where more than one de-icing/anti-icing pad is provided, consideration should be given to providing de-icing/anti-icing vehicle movement areas of adjacent pads that do not overlap but are exclusive for each pad. Consideration should also be given to bypassing of the area by other aeroplanes with the clearances specified in CS ADR-DSN.G.400.
