In the event of an engine failure during landing, which engines should have their throttle set to reverse idle?

Setting the throttle to reverse idle for all engines during an engine failure on landing is a crucial procedure that enhances safety and control of the aircraft. When an engine failure occurs, particularly during the critical phase of landing, it is vital to maximize the thrust and control available to maintain directional stability and deceleration.

By deploying reverse thrust on all engines, including the operative ones, the pilot can help counteract any yaw induced by the asymmetric thrust caused by the failure of one engine. This helps to stabilize the aircraft and ensures it remains aligned on the runway centerline, reducing the risk of runway excursions or loss of control. Moreover, utilizing reverse thrust can significantly shorten the landing roll, contributing to safer landings on shorter runways or in adverse conditions.

Implementing reverse thrust from all engines also aligns with procedural consistency, offering a uniform response to engine failure scenarios, which can simplify pilot decision-making. This comprehensive approach ensures the pilot has maximum braking capability and aids in a swift and controlled response during a critical moment.
