During an engine failure in flight, what should be the setting for the mixture?

In the event of an engine failure during flight, the correct setting for the mixture is to position it to idle or cutoff. This is crucial because it helps to prevent any potential flooding of the engine, especially if you are attempting to restart it. Reducing the fuel flow aids in conserving fuel and ensures that any remaining fuel is utilized efficiently.

Typically, the mixture is set to rich during normal operations to promote optimal engine performance. However, in scenarios where the engine is not operating, adjusting the mixture to an idle or cutoff position is important. This action is part of the emergency procedures outlined in the aircraft's operating handbook and can play a key role in managing the situation effectively.
