It describes a rule bound process to complete a thoroughly validated procedure to land in conditions of no or uncertain visibility down to DH or MAP. There is no page 2. You pull the page from your chart book, put it into the clip, and brief it and fly it. I have never done an approach briefing before the approach chart was in the yoke clip and on both sides. There was not a second page ever discussed in any briefing. Or is it displayed electronically? Whatever, if it is an approach plate, everything you need to know is on that one piece of paper.
Incorrect. On some Jeppesen approach plates, the copter minimas are on found on plate 10-9Y.
GOULI makes a good point about not only the radar return, but the spot height on the drawing being obscured by the waypoint symbol. From that, we are assuming that this chart was on the PF's MFD. No paper chart. The report says this "approach" was selected in the FMS. Does that result in the chart coming onto the MFD, or both MFD's for the briefing? If it's all canned and activated after the letdown, then it automatically shows the waypoint symbol as the goto waypoint.
No it does not. It simply means that by selecting the APBSS approach on the FMS, the corresponding waypoints will be added to the flight plan of the FMS. The preliminary report even refers to the operators route guide, and the second text page. It is a paper chart.
The letdown procedure was not flawed. It was completed a few miles from Blackrock. The flaw was in the belief that once completed, the hookup to BLKMO and on to Blacksod could be accomplished at 200 feet. The procedure was meant for a helicopter starting from the pad at Blackrock. It would have been easily adaptable to an IFR procedure with vertical guidance added. But it wasn't. It does seem to be the only option for an IFR approach to Blacksod, but this crew was in a VFR procedure.
You are making an assumption here. My assumption would definitely not be like yours. This is not a route from one helipad to another. It is a VFR arrival route from off the coast to Blacksod.
