What is ETOPS and what considerations does it add to dispatch planning?

• A. ETOPS is Extended-range Twin Operations; requires diversions to suitable airports, special maintenance/operational procedures, and longer planning for remote routes and fuel.
• B. ETOPS stands for Extended Takeoff and Overflight Procedures and is only relevant for tri-jet aircraft.
• C. ETOPS allows unlimited diversion options on all routes.
• D. ETOPS is not applicable to flight planning.

Answer: (C)

ETOPS defines how far a twin-engine aircraft may be from a suitable diversion airport in the event of an engine failure, and the standards that must be in place to operate those routes. Because of this, dispatch planning must verify the aircraft’s ETOPS approval and rating, ensure there are appropriate diversion airports within the permitted time window along the route, and confirm that maintenance, reliability, and operating procedures meet ETOPS requirements. It also drives fuel planning, introducing ETOPS-specific reserves and considerations for potential diversions or holds, as well as the need to choose routes and alternates that are certified for ETOPS operations. ETOPS does not grant unlimited diversions or apply to all routes indiscriminately; only routes and airplanes that are ETOPS-certified can be used for extended overwater or remote segments, and the diversion time window is defined by the certification.
