I've been following this interesting discussion from the beginning on both threads, and other than dropping in the odd graphic have just watched the flow and ebb. However, when looking at a pic taken after the #2 had been demounted and lashed to the trolley, I noted a stray pipe with a rather distressed look to what is now an open end. What would have been carried in this line? I assume this damage was caused by the disc burst.
Also, I believe that references have been made to the FDR graphics as published by the ATSB in their Interim Report. Those 5 graphs in their full size (1369 x 976 pixels) can be downloaded as follows:-
QF32-FDR-1
QF32-FDR-2
QF32-FDR-3
QF32-FDR-4
QF32-FDR-5
Reference to the engines #2 and #3 N2% scale in image #2 will reveal that the #2 readout has been offset vertically and the scale associated with both engines is corrupt. I suspect the correct scale is that above for N3%.
