What action should be taken with the mixture during an engine failure just after takeoff?

After an engine failure shortly after takeoff, the correct action regarding the mixture is to set it to idle cut-off. This action is typically recommended because, in the event of an engine failure, the pilot must aim to prevent fuel from entering the engine if a restart is planned. By moving the mixture to idle cut-off, the fuel supply to the engine is effectively stopped, thus facilitating a potential controlled descent and landing.

In the context of engine failure procedures, the focus shifts towards maintaining control of the aircraft and aiming for the best possible landing site. While a full rich mixture is generally desirable during normal operation for maximum engine performance, during an emergency like an engine failure, particularly if there is a risk of a fire, having the mixture at idle cut-off helps to mitigate that risk.

This procedure is part of the emergency checklist that ensures the pilot is taking appropriate steps to secure the aircraft and prepare for landing while also preparing for an emergency situation.
