Here's some questions for you.... (I don't know the answers, insufficient data in FCOMs).
How do the engineers disable/enable the ground spoilers? Through CFDS ?
When you press RECALL before start will a GND SPLR FAULT message appear if they are disabled?
If the Ground Spoilers are disabled, as opposed to faulty, will ECAM show amber ground spoiler indications, and when you arm them after start will you receive a GND SPLR FAULT message? If not, why not?
And why would a ground spoiler problem produce a SPLR FAULT message, or is that just sloppy reporting?
And for your interest there is a note in the abnormal procedure for SPLR FAULT.. If heavy vibrations are felt, CONF 3 may be used for landing in order to reduce the buffeting..
