B. Just with rudder and Diff. Thrust
Eerrm.... what rudder?
Perhaps there have been some modifications lately, but all 319/20 in our fleet have hydraulically operated rudder. It can be mechanically signalled in case of total electric loss, but there has to be at least one hyd sys alive. It might be yellow or green via eng pumps or blue via RAT but you definitively need hydro pressure to move it.
So was there a change in the flt ctl architecture or did I miss something?
