cpnpc - you seem slightly obsessed about the procedure being from LS (blackrock) to LS (blacksod).
Why would a company that doesn't do lighthouse transfer work and can't land the S-92 at Blackrock because the LS is too small, have a procedure to go from Blackrock to Blacksod?
Nonsense. Obsessed?
I'm not obsessed at all. It is a VFR arrival departure procedure from helipad to helipad. I have no idea why you don't want to admit that, yet you make the strongest argument that it is.
You are the one who asks, quite correctly, why a letdown procedure would be centered over the highest point out there in the ocean. BLKMO is marked because it is a helipad. Just like Blacksod is marked.
Who cares about the S92 not being able to land there? Is that the only questionable thing in this whole mess? Helicopters transit quite regularly between Blacksod and Black Rock. At some point, CHC may have operated helicopters that can be operated there. Other agencies of the Irish government may provide the helicopters. The route may have been designed before the S-92's and added to CHC's route book.
How to fix this. Put large black letters at the top of APBSS that say "For VFR use only". And for good measure "No PT" beside BLKMO.
