bobcat4 Well learning from the experience of this accident I would suggest that in respect to the NG set-up the overriding design parameter of the RETARD function ought be ensuring that the A/T is only able to command RETARD at 27'RA and nowhere else, then build from there.
Note: the RETARD function is also invoked momentarily with LVL CHG but this doesn't involve the RA.
