I agree that more specific detail of the approach brief would have been useful. It is possible that there were deficiencies in the approach brief, which could imply the assignment of blame if mentioned. For example we know that the height of Black Rock is mentioned on page 2 of the approach document, but did the crew read that? It also appears on the chart, but was possibly covered by other data on the MFD. Certainly the radar display appears as if it was compromised by other overlaid data.
We have identified an inadequate approach plate, flawed let down procedures, radar display being compromised by overlay data, do we really need to go much further than that?
Sorry our posts crossed, but I think we are in agreement.
