## GM1 ADR-DSN.C.215 Dimensions of runway end safety areas

It is accepted that many aerodromes were constructed before requirements for RESAs were introduced. For applicable runways where the RESA does not extend to the recommended distance, as part of their [Safety Management System](https://avioverse.aero/glossary/easa/safety-management-system), aerodromes should assess the risk and implement appropriate and suitable mitigation measures as necessary.
