The Regulation will require operators to take “actions to mitigate the risk” of aviation safety hazards. The draft Acceptable Means of Compliance requires safety mitigation to an ‘acceptable’ level, and ICAO and UKCAA guidance documents both use the term ‘as low as reasonably practicable’ (ALARP). A court would consider whether an operator had met the requirements and best practice. An ‘Acceptable Level of Safety’ (ALoS) is determined by the State as part of its high level State Safety Plan for its aviation sector. (last updated September 2012)
