Mr Purdey,
correct me if I'm wrong but your viewpoint, and that of Mr Wratten is simply this - the crew changed the waypoint to Corran and then about 15 seconds later crashed into the Mull because they flew straight on.
Could you then, please tell me the time that the waypoint change was made, and provide factual evidence to support your claim.
According to the AAIB and Racal, there is no record of what time the waypoint change was made.
Perhaps the crew made the waypoint change a few minutes earlier then spent those few minutes struggling with the controls, or were distracted by a spurious caption light. Perhaps not. They may even have done a bit of sightseeing - who knows!
Whatever your opinion, the mere fact that it is not known what time the change was made (and therefore the flight time, and profile, between the waypoint change and impact is unknown), throws into question the very simulation that everyone bases their negligent claim on.

Kind regards, as always.
