Power reserve for engine failure is activated in which mode?

Power reserve for engine failure is activated in which mode?

• A. Automatic activation
• B. Manual activation
• C. Disabled
• D. Not available

Answer: (A)

Power reserve for engine failure is meant to respond automatically so the aircraft can maintain safe performance without relying on pilot input. When an engine fails, the remaining thrust must be quickly and reliably increased to keep the airplane in a controllable flight path, especially during critical phases like takeoff or initial climb. An automatic activation ensures this protection activates the moment the system detects the failure, providing the needed power reserve instantly and reducing pilot workload and reaction time in a high-stress situation. If it required manual activation, there could be dangerous delays or underperforming climb and speed maintenance while the crew confirms the failure and executes a procedure. Disabling or not having the feature would remove this automatic safeguard, leaving performance to chance rather than a designed response. So the mode that best guarantees immediate, dependable protection in an engine-out scenario is automatic activation.
