In an ATR, when an engine fails in flight, which action is essential to address the situation?

• A. Immediately descend to minimum safe altitude
• B. Maintain control, set appropriate airspeed and configuration, follow engine-out checklist and communicate with ATC; consider routing for landing.
• C. Extend landing gear and flaps immediately
• D. Return to origin without ATC coordination

Answer: (B)

When an engine fails in flight, the priority is to keep the airplane under control and set it up for a safe landing. The essential action is to maintain control, manage airspeed and configuration for engine-out flight, work through the engine-out checklist to identify and secure the failed engine, and communicate with ATC while considering a landing route. This approach preserves handling qualities with one engine inoperative, minimizes drag, and ensures you have a clear plan for a safe emergency landing with priority routing.

Why this matters: keeping control and proper configuration gives you the best chance to maintain stable flight and the necessary glide performance to reach a suitable airport. The engine-out checklist provides a disciplined sequence to verify the failure, secure the affected engine, and set up the aircraft correctly for continued flight and landing. Clear ATC communication helps you gain priority and organize traffic flow to a safe landing site.

Other options don’t fit as the immediate, comprehensive action. Descending to a minimum safe altitude too early can reduce options and increase risk; extending landing gear and flaps immediately isn’t universally appropriate and can add drag or undesired surprises without following procedures; returning to the origin without coordinating with ATC ignores essential airspace management and could create conflicts with other traffic.
