Hi Capt Galactic,
I don't think there's requirement to look for Vref in the QRH. If the MCDU is giving you the VLS Conf full, just take it from there.
Also, not too sure about the requirement to add min 5kts for the A/THR if in Abnormal/Emerg. The QRH 2,40 only has this requirement for the top table (Normal ops). Yes, I do know the Vol3 Supp proc, states the +5kts for the A/THR as well...
Thanks for your further thoughts
