Interesting that she also made a point of saying that the "Instructor Pilot" (PNF) asserted that he was the PIC. Interesting in that they are exploring the relationships between the three flight deck crew.
I would certainly expect the instructor pilot to be PIC if the captain under training had not completed IOE (or OE as it is now called) on the Triple. At least that's how it works in the U.S. in my experience.
Maybe my previous post about possibly transitioning from a low erroneous computed FMS path to a higher real world PAPI was too technical, it seems to have disappeared.
Now it looks like the situation was the opposite, high and fast with 180 knots to 5 miles, V/S 1500 fpm down to get on the PAPI. Then A/T off (but still armed), back to idle presumably. Nose up, but power still back when the PAPI's go red...
For a non-pilot I think Debbie Hersman is doing a terrific job of explaining the findings and the technical aspects of the automation and warnings.
