help Boeing 747-400 FAQ
Why does the Boeing 747-400 have winglets while earlier 747s usually do not?
The 747-400's approximately six-foot winglets reduce induced drag and help improve fuel efficiency on long flights. They are one of the easiest ways to distinguish a standard 747-400 from most 747-100, 747-200, and 747-300 aircraft.
Did the Boeing 747-400 need a flight engineer?
No. Its digital glass cockpit allowed a two-pilot flight deck, unlike earlier 747 variants that normally carried a flight engineer.
Which airlines were closely associated with the 747-400?
British Airways, Lufthansa, Qantas, United Airlines, and Singapore Airlines all operated substantial 747-400 fleets. Qantas also used a newly delivered 747-400 for a nonstop London-to-Sydney demonstration flight in 1989.
What replaced the Boeing 747-400 on long-haul airline routes?
Many airlines replaced it with more efficient twin-engine aircraft such as the Boeing 777-300ER, Boeing 787, and Airbus A350. The later Boeing 747-8 continued the jumbo-jet design, but sold in much smaller numbers than the 747-400.
