I'm with mcdhu here, how could any competent crew fly any approach without monitoring both the lateral profile and the vertical profile. Okay, they saw the localiser neatly aligned, but did they honestly just sit there and make absolutely no effort to monitor the vertical profile?
I've used FPA before - albeit not on a Bus, but did these guys ever wonder how the automation was positioning the aircraft. Did they really just hit the mode button and expect to be on profile all the way to MDA?
