FWC
Flyingnewbe - Updating the software on the AB is not a problem it is actually being done continuously. Not very often but there have been several software updates. Just a matter of replacing a computer card into the FWC. Could be done in an hour or so.
Manual Spoliers can be used in Config Full when on the ground.
The thrust lever could only be stuck if it was Jammed by a foreign object. Alpha Floor does not lock the thrust lever - it locks the thrust. The TL can still be moved. There is no motor that drives the TL they must be moved by hand.
To overcome the ecam 'thrust lock' - Move the TLs.
Releasing of the FDR/VR in this way is absolutely scandalous. IMHO.
