Just read the latest AAIB report (link emailed to me).
My eyes were also drawn straight to the paragraph about the autopilot modes in use at the time.
As a "3 axis only" rotary autopilot user, (not Puma) I'd be most interested to know what the company SOP is, regarding which AP modes should normally be engaged during an ILS approach.
"VS" mode isn't one I would choose to use at that stage of flight, although I do often use it for the initial descent, or for a non-precision approach.
