Thanks mm43 for your research, I was expecting some inputs from Svarin A33Zab PJ2 takata ... but none of them seem to be around lately.
There is still so much to analyze on the little FDR data we've been given ...
Is it possible, the captain, after suggestion from the PNF, did switch OFF both PRIM and SEC 1 ?
Was it done in an attempt to force Direct Law or something ?
The other, you did post something of interest from the Instructor Manual ... By any chance, would you have a link for that manual ?
