What if you use one of the SAR modes to make an approach to BKSDC using a northeasterly heading along the long axis of the inlet?
One could incorporate Blackrock as an IAP at which descent from the MSA could be initiated....that would have been pretty much a crosswind approach and a final turn at "C" for the run-in to Blacksod
As I understand the S92 AFCS capabilities you can press a button to mark a target at height and it will fly a fully coupled approach to that point to a pre-determined height (very probably 200') so as long as you were positioned somewhere a couple of miles from Blacksod to give adequate coastal clearance, you don't have to go all the way to Balckrock at all.
