All makes sense to me, what doesn't make sense is an experienced crew simply getting mixed up between Blacksod and Blackrock or the locations being entered wrong in the FMS.
Touching on the update released. I wonder if they did get a HUMS download from the actual accident flight or whether they are referring to the flight previous. I have a feeling the S92 system is the same as the Airbus system where the card session needs closing (by way of Engines powering down) For example, I'm certain if a HUMS card is removed from the card slot mid flight, there wouldn't be any data on it. They were not able to download the EC225 or indeed the AS332L2 accident data, only the data from the flight previous. I would also imagine that if they did manage to somehow get the HUMS data downloaded, there would be huge jumps in the data from the impact with blackrock to the loss of the tail and the time it took to strike the water, all that would have been recorded on the graphs.
Certainly pointing towards a CFIT from their update though.
I'm not sure that the HUMS data is that relevant if the FDR shows that the helicopter's flight path was as expected for the control inputs.
