IMHO the last 2 posts emphasize the confusion that reigns. What Leon says sounds sensible, but DV was just quoting what the MAA DG said. And DV is right saying it is
risk of collision that's at issue, not an
outcome of collision.
And then further confusion raised by the legal services advice issued 22 years ago. I think that's a quite important question because if no-one knows why MoD changed back again to using numbers, how do we know if the legal advice itself was changed? That would be another reason to question the validity of RA1210.
