In the event of an engine failure during takeoff, which thrust is commanded on the operating engine?

In the event of an engine failure during takeoff, the operating engine is commanded to deliver maximum thrust. This practice is critical because when one engine fails, the aircraft experiences a loss of performance and may not maintain a safe climb rate. By commanding maximum thrust on the operating engine, the flight crew ensures that the aircraft can achieve the best possible performance to maintain control and altitude as it gets airborne.

Utilizing maximum thrust allows the pilot to compensate for the asymmetric thrust created by the failed engine, which can cause the aircraft to yaw towards the dead engine. The goal is to ensure that the aircraft can climb away safely with the available power, providing a margin for recovery in case of any other difficulties during this critical phase of flight.

While normal thrust or reduced thrust could be standard operating procedures during typical takeoff conditions, these settings would not be appropriate in an engine failure scenario, as they would not provide sufficient power to overcome the performance deficits caused by the failure. Idle thrust would not provide the necessary lift and control, making it unsafe for takeoff. Therefore, maximum thrust is the correct command to ensure the aircraft's safety and performance during such an emergency.
