You miss the point entirely although you ask the right question!
If the SAR modes can safely deliver you directlyto the helipad in a stabilized hover if asked to do so...why not ask it to do so...or at least to a point very close to the helipad?
As Blacksod, like other known deliberate Landing Sites used by the Operator, did not have a documented IMC approach procedure, one that assured track and vertical guidance guaranteeing Terrain clearance....one has to ask...."Why?".
Why did the Crew choose a point Ten Miles from the Helipad instead of a point very close to Blacksod itself?
Had that IMC approach existed and been used....this Crew would not have been at 200 feet and ten miles out to sea heading ashore as they were when they hit Blackrock.

Had an "old" technique been used, we would not be having this discussion. SAR modes are for SAR, not routine landings for a fuel stop when there was no urgency. As gulliBell says, why start an approach at 200' essentially IFR (night) with miles and miles to run at 75 knots?
Its the "new" techniques that lead to a false sense of security. I always sought to minimise my time over the sea at at 200' as I am sure you did SAS.
