## GM1 ADR-DSN.B.150 Runway strip to be provided

(a) A [runway strip](https://avioverse.aero/glossary/easa/runway-strip) extends laterally to a specified distance from the [runway](https://avioverse.aero/glossary/easa/runway) centre line, longitudinally before the [threshold](https://avioverse.aero/glossary/easa/threshold), and beyond the runway end. It provides an area clear of objects that may endanger aeroplanes. Any equipment or installation required for air navigation or for [aircraft](https://avioverse.aero/glossary/easa/aircraft) safety purposes and is located in this object-free area should be frangible and mounted as low as possible. The term ‘aircraft safety purposes’ refers to the installation of arresting systems.

(b) When the threshold or end of the landing distance do not coincide with the ends of a runway, the runway strip enclosing the runway and any associated [stopway](https://avioverse.aero/glossary/easa/stopway) should extend to the lengths specified in CS ADR-DSN.B.155 at the widths specified in CS ADR-DSN.B.160, based on the threshold, end of landing distance or end of stopway, as appropriate.
