Squidlord:
(Oh, and strictly, I disagree with Chugalug2 when (s)he suggests that if regulation is not followed, it necessarily means the software is unairworthy. However, I do believe that if regulation is not followed then it is very unlikely that the software could be satsifactorily demonstrated airworthy (as required) - a subtle distinction.)
A subtle distinction indeed, Squidlord, and one no doubt eagerly seized upon by those who have so assiduously managed to undermine UK military airworthiness, thus leading to the Regulations being totally flouted over the past few decades. Better by far that such temptation be removed entirely from the CoC by moving responsibility for enforcement to a separate and independent MAA, and likewise an MAAIB, who would ensure that the Regulations are indeed followed, and demonstrated to have been so. The bread and butter of the CAA and AAIB of course!
