I don't have acess to A321 performance data, as I have only flown the A320, and that was some time ago. However:
- if anything, the Vmc speeds on the A321 should be lower than on the A320 due to longer fuselage. Correct me if I am wrong
- the takeoff was conducted with a light-ish airplane on a short, wet runway. It is very possible in such conditions to have the V-speeds limited by Vmca/Vmcg/Vmu and be lower than what we are normally used to see. On longer runways the V-speeds are usually higher in order to improve climb performance.
According to the report mentions V1 of 112kt and Vr of 123kt @68.6T. Does it really sound so low?
Can anyone post published Vmcg and Vmca for the A321 and stall speed in Conf3 for 68T? I remember there used to be a stall speed graph in the FCOM. Min V2 can be as low as 1.13*Vs1g
Or even better, do a calculation in FlySmart? The wx/rwy conditions are described in the report.
