What is VMC?
Conditional airspeed - based on factors such as weight, alt and airspeed, minimum speed where rudder is sufficient to counteract turning forces after losing an engine (primarily the critical engine)
What is VMC tested to assure?
Tests to stop the turn that results when the critical engine is suddenly made inoperative within 20 degrees of the original heading, using maximum rudder deflection and a maximum of 5 degrees angle of bank into the operative engine.
Thereafter, maintain straight flight with no more than a 5-degree angle of bank.
Why does VMC testing bank 5 degrees into the working engine and how effective is it?
Increase lift on the failed engine wing due to loss of propwash lift
Tests have shown that Vmc may increase more than 3 knots for each degree of bank less than 5
degrees.
Loss of directional control may be experienced at speeds almost 20 knots above published Vmc when
the wings are held level.
