Thanks for the replies Safetypee & J T.
JT - No I don't want to be airborne below VR & V2 on take off - but on the approach & GA (+ in the same configuration Flaps 3) I can fly 12 kts slower than V2.
It seems to me that V2 VMCA must assume wings level (else how did I get off the ground and be under control). However VAPP VMCA allows 5 degs bank.
Standing by for flame throwers.
