This raises a question:
speed trend vectors are purely inertial ("GS knots to be gained in 10 sec") or it is converted to "IAS knots to be gained in 10 sec"?
I think incidents like those can be detected before lining up, if the computer rejects Vr or V2 speeds non consistent with GW and thrust.
Any reference for 320s used by Airbus test pilots like that of the 737s?
