By 1985 the ETOPS rule was modified to 120-minutes, with the possibility of extension to 180-minutes for operators who could prove one year of issue-free service at ETOPS 120, allowing twin-engine aircraft to more economically service routes which had been held tightly by the Boeing 727, McDonnell Douglas DC-10, and Lockheed L-1011 TriStar. When Boeing requested a waiver from the 60-minute Extended Range Twin Operations (ETOPS 60) rule for the 767-200ER, the administration re-affirmed the need for the 60-minute rule with exception to the Airbus A300 which could continue to operate under an ETOPS 90 waiver in specified regions. ![]() Up until the 1980s, FAA policy had been that twin-engine jet aircraft could not operate overwater further away from a land-based divert airport than 60 minutes at the single-engine cruise speed. The type was meant to provide a middle-ground in seating within the wide body jet airliner category between the Boeing 767 (767-300: 210 seats in 3-class config) and the 747 (747-400: 416 seats in 3-class config) with the first variant, the 777-200, delivered with 305 seats in a 3-class configuration.įurther, the 777 served as a replacement to tri-motor jet airliners.
