The DfT spec for aircrew experience was unchanged across both the February and September versions, though I suppose the unpublished final ITT could have been different. The figures in those documents are similar to what's in the Bristow ad shown above but the type and SAR figures are higher in the ad. Then there is the term in the DfT spec for the Commander that requires 'on each type' which does not appear in the ad.
[See ITT (19 Sep), Schedule 2.1, Specification, Section 2.3.1.]
