What benefit does the right engine provide during a left engine failure scenario?

In the scenario of a left engine failure, the right engine plays a crucial role in counteracting the aircraft's tendency to yaw towards the left. This yaw occurs because the left engine's thrust is no longer present to provide balance. The asymmetrical thrust results in a loss of directional control, causing the aircraft to be drawn towards the side of the failed engine.

The right engine, by continuing to produce thrust, helps to counter this leftward yaw. By adjusting the power from the right engine, the pilot can create a more balanced thrust vector, allowing the aircraft to maintain a straight flight path or mitigate the undesired yawing motion. Maintaining control in this way is essential for safe flight operations, especially during situations where one engine has failed.
