Airplane airborne and the ground effect negligible (section 23.149(b)). ⦁ Maximum of 5° angle of bank (section 23.149(a)). VMC is highly sensitive to bank angle. To prevent claims of an unrealistically low VMC speed in aircraft certification, the manufacturer…

maintain straight flight at VMC with a bank angle of not more than 5°. This more closely resembles the VMC demonstration task in the practical test for a multiengine rating. The AFM/POH-published VMC is determined with the critical engine inoperative ... critical engine is the engine whose failure had the most adverse effect on directional control. On twins with each engine rotating in conventional, clockwise rotation as viewed from the pilot's seat, the critical engine will be the left engine…
