I'm trying to find it for you, I had it in a presentation somewhere I am sure but no joy so far, I thought it was in a CFM ops seminar but can't see a reference now (unless I'm completely loosing the plot and thinking of the V2500). Any one else know?
Looking through the CFM seminar, if it detects any decel greater than expected on normal schedule (among other things) it will immediately engage dual ignition anyway.
