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

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

IR Implementing rule

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

(a) The safety objective of the clearance distances on a [de-icing/anti-icing pad](https://avioverse.aero/glossary/easa/de-icinganti-icing-pad) is to provide safe separation between an [aircraft](https://avioverse.aero/glossary/easa/aircraft) using the stand and any adjacent building, aircraft on another stand and other objects.

(b) A de-icing/anti-icing pad should provide the following minimum clearances between an aircraft using the stand and any adjacent building, aircraft on another stand and other objects:

| Code Letter | Clearance |
| ----------- | --------- |
| A           | 3.8 m     |
| B           | 3.8 m     |
| C           | 4.5 m     |
| D           | 7.5 m     |
| E           | 7.5 m     |
| F           | 7.5 m     |

(c) If the pad layout is such as to include bypass configuration, the minimum separation distances specified in Table D-1, column (13) should be provided.

(d) Where the [de-icing/anti-icing facility](https://avioverse.aero/glossary/easa/de-icinganti-icing-facility) is located adjoining a regular [taxiway](https://avioverse.aero/glossary/easa/taxiway), the taxiway minimum separation distance specified in Table D-1, column (11) should be provided (see Figure G-1).
