What'the Documentary Unit number for the Status page of the B+Y in your FCOM?
Aircraft with FWC F10 and later have an evolution in every ECAM alert with a mono elevator where the Vapp is faster on some type of aircraft.

1. With G+Y fail you are in Alt law, loose flaps and needs adding of 25kts to Vref
2. With G+B fail you are in Alt law, loose slats and half elevator and needs addition of 25kts to Vref
3. With B+Y fail you remain in normal law can extend both slats and flaps but loose half elevator.
And yet the FCOM says (B+Y) if Flap3 Vapp Vref+25. It's silent on flaps full.
If you go to QRH Inflight Performance landing distance chart(now removed) it offers both options in flaps full with zero ∆Vref and Flap3 with only 6kts ∆Vref.
Doesn't make any sense to me. Has anyone got an answer from techrequest?
