Arba,
please reread my post#60.
ETP designed to be flown at not more than V2 due to obstacles/noise when being in a light,aft CG aircraft and having to turn on the side of the failed engine and not banking 3-5 degrees away from the bad engine,with also spoiler turn assist on 737s can lead your aircraft to become uncontrollable and leading to a disaster.
VMCA was determined using bank into the good engine,using the boeing technique of using rudder to get the control column in the neutral position(bank) does not satisfy the requirement of maintaining a demonstrated VMCA in case of a minimum V2 take off.
Therefore the possibility of losing control.
