## CS ADR-DSN.C.215 Dimensions of runway end safety areas

(a) Length of [runway](https://avioverse.aero/glossary/easa/runway) end [safety area](https://avioverse.aero/glossary/easa/safety-area)

(1) A runway end safety area should extend from the end of a [runway strip](https://avioverse.aero/glossary/easa/runway-strip) to a distance of at least 90 m and, as far as practicable, extend to a distance of:

(i) 240 m where the code number is 3 or 4 and

(ii) 120 m where the code number is 1 or 2 and the runway is an instrument one; and

(2) A runway end safety area should extend from the end of a runway strip, as far as practicable, to a distance of 30 m where the code number is 1 or 2 and the runway is a non-instrument one.

(b) Notwithstanding the provisions in (a) above, the length of the runway end safety area may be reduced where an [arresting system](https://avioverse.aero/glossary/easa/arresting-system) is installed, based on the design specifications of the system.

(c) Width of runway end safety area

The width of a runway end safety area should be at least twice that of the associated runway and, wherever practicable, be equal to that of the graded portion of the associated runway strip.
