The CF6 Engine
The CF6 engine family is the cornerstone of the widebody engine aircraft business.
For 45 years, the CF6 engine family has established an impressive operational record. CF6 engines have compiled nearly 430 million flight hours since they first entered commercial revenue service in 1971. Certified to power more than 13 different aircraft types, the CF6 has accumulated more than 115 million flight cycles in service.
The Qantas flight from Dallas to Brisbane is one of the world’s longest nonstop commercial flights, and GE’s CF6 engines help make it possible. The flight (Qantas flight QFA8) from Dallas, Texas to Brisbane, Australia uses a Boeing 747-400 aircraft and is powered by four GE CF6 engines. The flight typically lasts over 15 hours and covers nearly 8,500 miles. It means tourists traveling from North America can start their dream vacations in Australia the very next day.
The CF6-80A and -80C2 engines are known for their high reliability, and this was evident during extended twin operations (ETOPS) testing. Both engines received 180-minute ETOPS approval on the Boeing 767, and the CF6-80C2 engine received 138-minute ETOPS approval on the A300 and A310 aircraft that allowed twin-engine aircraft operations over large bodies of water.
