I don't have specific answers but if you can find a copy of the QRH of an A300 have a look at section 13.01-13.03-Unreliable airspeed.
I will quote you a few power settings/pitch attitudes for 140 tons (MLW)
Clean (green dot-225kt) pitch +4 N1 62%
270kt(turb speed) +1.5 73%(Fl100)
S speed +6 66%
F15 speed +6 67%
F20 +6 72%
Gear down F40 +3 65%
The speed trend arrow is very useful
