Is it not from Blackrock pad to Blacksod pad?
No, I think that it is a legacy procedure going from an obvious local feature (Blackrock) to the intended LS of Blacksod. There is no reason to think of Blackrock as a LS or helipad because it is no use in any way shape or form to a SAR helicopter - the idea that it is a route from one LS to another I think is nonsense.
Trouble is, in the middle of the night when you are tasked to the area and need to get to the refuel site, it is too easy to pull out the company letdown chart and follow it without thinking about what you are actually doing.
I think there are a lot of questions to be asked about the company procedures in Ireland and I would be surprised if in UK Bristow and HMCG are not taking a long look at their procedures to ensure they are squeaky clean and appropriate to the terrain.
