SS inoperative
When reviewing the FDR traces for my last contribution i stumbled on the the bottom lines on page 108 of BEA interim report N. 3.
At about 02:11:40 their is a spike indicating FO SS inoperative and a longer one shortly thereafter with Captain SS inoperative. It happens the same time, the THS and elevators reached Full Nose up. At the end the same indication Capt. SS inoperatie shows up again.
WHat would have caused this indication? Has it something to do with the priority button?
