FAQ n.44271

Our analysis show that the Continuity meets the Implementing Rule / AMC 20-24 requirement, but not the CS-ACNS requirement.

Answer

CS-ACNS requires compliance to a qualitative probability of ‘remote’, which corresponds to a quantitative probability of 1E-5 / F.H. This is more challenging to meet than the Implementing Rule Annex II and AMC 20-24 figure (2E-4 / F.H.). 

A deviation to this requirement may be accepted on a case-by-case basis and under conditions by the Agency after review of the compliance data. Such a deviation is published by EASA under reference ‘Deviation Request CS-ACNS#1’. 

No deviations to the requirements of the Implementing Rule will be granted.
