Plain English Meaning

The set of ideas a pilot needs to understand to fly a twin-engine airplane safely when one engine has quit. With thrust now coming from only one side, the airplane wants to yaw and roll toward the dead engine, climb performance drops sharply, and the pilot must use specific rudder and bank techniques to stay in control.

Full Definition

The aerodynamic and control concepts that govern how a multiengine airplane behaves and must be flown when one engine has failed or has been intentionally shut down. These principles cover the asymmetric thrust and yaw produced by the operating engine, the resulting roll tendency, the loss of airflow over part of , the reduced climb performance, and the rudder and bank inputs required to keep the airplane controllable and on a safe .
