fredgrav, I was just about to give you the ref. (FCOM 1.27.10 p12 in "note" for A320/321 only) when I realised that I wrote a wrong statement myself

Allow me to correct it: in autoland, gnd spoilers will extend only if you move back the TL to Idle like in any other landing!
The note I am referring to is actually only detailing the extension moment and rate of the spoilers, nothing else:

It is only one condition for spoilers extension, not the only condition as I wrongly said previously.
I found out with this:
We drifted big time from the subject though...
Cheers
