![]() You're mistaken. ETOPS stands for "Engines Turn Or People Swim". :-) FlyWithTwo wrote: The FAA/JAA terminology for this type of certification was ETOPS (Extended-range twin-engine operations). The plane, along with engines and complement of nav/com systems, is certified to fly on one engine for more than one hour from an airport when over water. Based on cumulative reliability, the length of time can be extended. Certain versions of twins like the B757, B767, A310, A330 were approved for ETOPS. The B777 was actually ETOPS approved from the launch date - quite an accomplishment for a new plane with new engines. One of the marketing battles between Airbus and Boeing was the A340 versus the B777 - four engines versus two. ETOPS had a lot to do with the success of the B777. In the satellite communications community, we used to refer to ETOPS as "Engines Turn or Passengers Swim". Brian |
