They didn't have ALT.A coupled according to the report, just VS. Unless I have read it wrong.
I was trying to clarify the phrase 'coupling to pitch' since it could be pitch channel, pitch attitude or collective pitch.
My mistake, ALT.A was not selected. Perhaps passing of time had blurred my memory - that's my excuse anyway

As for coupling modes, I've always talked about the principal axes of motion as being pitch, roll and yaw. A certain French manufacturer does confuse things by having blade pitch as a fundamental measure of collective application, but I dismiss such things as an aberration of poor judgement and odd Gallic tendencies
