What occurs when operating a multiengine airplane with one engine inoperative?

When a multiengine airplane is operated with one engine inoperative, the concept of Vmc, or minimum control speed, becomes crucial for the pilot. Vmc is the minimum airspeed at which the airplane can be controlled with one engine inoperative. By banking towards the inoperative engine, the pilot aligns the airplane's lift vector more directly against the yawing moment caused by the thrust from the operating engine. This is essential because the operating engine creates an asymmetrical thrust that tends to turn the airplane toward the inoperative engine.

Banking toward the inoperative engine increases the load on the wing that is producing lift and consequently, the required airspeed to maintain control also increases. This phenomenon occurs because the increased bank angle alters the airflow over the wings, thus requiring a higher speed to achieve the necessary aileron effectiveness and control authority. Therefore, understanding this relationship helps pilots to make informed decisions about aircraft control and performance in the critical phase of flying with an engine out.

The other options suggest alternative effects of banking on Vmc that do not accurately represent the aerodynamic principles at play when dealing with engine-out flight scenarios.
