# CS ADR-DSN.D.260 Taxiway minimum separation distance

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.D.260 Taxiway minimum separation distance

(a) The safety objective of minimum taxi separation distances is to allow safe use of taxiways and [aircraft stand](https://avioverse.aero/glossary/easa/aircraft-stand) taxilanes to prevent possible collision with other aeroplanes operating on adjacent runways or taxiways, or collision with adjacent objects.

(b) The separation distance between the centre line of a [taxiway](https://avioverse.aero/glossary/easa/taxiway) and the centre line of a [runway](https://avioverse.aero/glossary/easa/runway), the centre line of a parallel taxiway or an object should not be less than the appropriate dimension specified in Table D-1.
