I'm guessing the possible loss of SAS perhaps went unnoticed in the heat of the moment, and again perhaps, explain the large pitch and roll excursions. 212man or other drivers care to comment.
Brian, I am making an assumption (possibly incorrect) that the AFCS similarities between S-92 and the various Hawks are sufficient that similar loss of flight control quality would be experienced if the generators dropped off line.
As to undervoltage vs underfreq, good catch, Jack, my memory isn't as good as I thought. I think the Hawk WoW switch functions as you state.
