## CS ADR-DSN.D.335 Holding bays, runway-holding positions, intermediate holding positions, and road-holding positions

(a) [Holding bay](https://avioverse.aero/glossary/easa/holding-bay)(s) or other bypasses of sufficient size and adequate construction should be provided where necessary, to make deviations in the departure sequence possible.

(b) A [runway-holding position](https://avioverse.aero/glossary/easa/runway-holding-position) or positions should be established:

(1) on the [taxiway](https://avioverse.aero/glossary/easa/taxiway), if the location or alignment of the taxiway is such that a taxiing [aircraft](https://avioverse.aero/glossary/easa/aircraft) or vehicle can infringe an [obstacle limitation surface](https://avioverse.aero/glossary/easa/obstacle-limitation-surface) or ILS/MLS critical/[sensitive area](https://avioverse.aero/glossary/easa/sensitive-area) or interfere with the operation of radio navigation aids;

(2) on the taxiway, at the intersection of a taxiway and a [runway](https://avioverse.aero/glossary/easa/runway); and

(3) at an intersection of a runway with another runway when the former runway is part of a standard taxi-route.

(c) An [intermediate holding position](https://avioverse.aero/glossary/easa/intermediate-holding-position) should be established on a taxiway at any point other than a runway-holding position where it is desirable to define a specific holding limit.

(d) An emergency access [road](https://avioverse.aero/glossary/easa/road) should be equipped with road-holding positions at all intersections with runways and taxiways.

(e) A [road-holding position](https://avioverse.aero/glossary/easa/road-holding-position) should be established at each intersection of a road with a runway.
