Except for failure cases--- flapless or emergency landing after a MTOW TO Think not likely, although I accept that it might be the case with certain types, I don't think it ever gets limiting in the LDG cases, RTOW---is for TO---
-- so unless your MRTOW was limited by Vmbe And it's a Mayday situation then it is unlikely that your Vref will ever approach such limits in normal
operation Vref is 1.3 vso [even with gust/wind additives not removed prior to touchdown and even at high DAs]---
Vref is 1.3 vso---Vso at Ldg weights/ configurations, whereas V1 may be a large factor of Vso in TO weights/ configurations---and at only few points on the the TO WAT tables would Vbe be limiting---
at least as far as I know
