TL2 remains in CLB and ENG2 EPR is fixed at value it was at the time of A/THR disconnection, approx 1.2 EPR (a typical approach setting).
Spoilers fail to deploy and autobrake not activated.
Just wondering - what's the biggest problem here ? Obviously one engine producing 1.2 EPR thrust is not good news but I would say that the real killer is the no spoiler / autobrake. Without them, even with the 2nd engine on idle, it is very likely that they would overshoot.
...and there was simply no way around it, even if they had a full understanding of what was going on (short of going around, but not recommended once T/R are deployed)
I am still convinced that the 320 systems can be improved - lets just start by making that dreaded Service Bulletin urgent and mandatory !
As an aside note: is there any material (here on elsewhere, haven't manage to google it) describing the design decision (and expected gain) of not having feedback built in the T/L mechanism ?
