Configuring the airplane.

ACS element text (the applicant demonstrates understanding of)

Configuring the airplane.

Bottom line

VMC has nothing to do with climb performance, and many light twins will not maintain level flight near VMC with one engine inoperative. Tests have shown that VMC may increase more than 3 knots for each degree of bank less than 5 degrees. In OEI flight, no instrument directly tells the pilot that the airplane is being flown at zero sideslip; the aircraft must be placed in a predetermined attitude of bank and ball deflection.
