1. Similar, but not the same. FCOM 1.27.20 P3
2. RED "MAN PITCH TRIM ONLY" on PFD means that you are in mechanical backup mode while AMBER "use man pitch trim" is an indiction of the direct law. Can you get this message and not be in the direct law? I can't think of any but then I'm no A330 expert. FCOM 1.27.30 P4 & P5
3. Dunno. Just curious: what's the exact title of the ECAM procedure you're reffering to?
Cheers, C.
