GE90-Powered 777 Receives 180-Minute ETOPS Approval
EVENDALE, Ohio - The U.S. Federal Aviation Administration (FAA) has granted the GE90-powered Boeing 777 180-minute extended-range, twin-engine operations (ETOPS) Type Design Approval. The aircraft is scheduled to begin ETOPS revenue service in late October with British Airways.
The GE90-powered Boeing 777 completed all 180-minute ETOPS requirements in August after flying a demanding 1,000-cycle Early ETOPS flight test program. FAA Type Design approval confirms that the engine/aircraft combination has the reliability to conduct ETOPS operations up to 180 minutes flying time from a primary or alternate airport. ETOPS approval provides airlines much greater route-scheduling flexibility as it allows twin-engine aircraft to service routes traditionally reserved for three- and four-engine aircraft.
The GE90, initially certified up to 85,000 pounds takeoff thrust, has achieved an outstanding in-service record since its initial delivery in late 1995. The engine is currently in service on four British Airways and two China Southern 777-200 aircraft derated to 76,000 pounds thrust. To date, this fleet has logged more than 25,000 flight hours while maintaining a 99.96 percent dispatch reliability rate. The GE90 is also demonstrating excellent performance retention, resulting in lower fuel burn, longer on-wing life and lower maintenance costs to airline customers. In addition, the GE90 has the lowest noise signature of any engine in its thrust class.
In July, the 92,000 pounds thrust GE90-92B became the highest-thrust engine ever certified by the FAA. The engine began flight testing on the Boeing 777 derated to 90,000 pounds thrust in September and will soon begin flight testing on the new Boeing 777-200 IGW (Increased Gross Weight) aircraft at this thrust rating. The GE90 will be the first engine to enter service on the 777-200 IGW when British Airways and China Southern take delivery early next year.
