747 REPLACEMENT – Is The Boeing 777X Perfect?



More and more airlines are retiring their Boeing 747 in favour of twin-engine, more efficient aircraft types. But what aircraft is specifically pitted as the ideal 747 replacement? Can the upcoming Boeing 777X be considered the perfect or most ideal replacement, all things considered?

  1. If the turbo fan is big enough why would you need 4 engines. 110 tons of thrust per wing 220 tons total is the same from 2 or 4 engines. Only war zones and VIP need the redundancy over better fuel economy.

  2. If the high-wing designs that NASA and others have been considering turn out to be the next big thing, huge turbofans with even-higher bypass ratios will have plenty of room under those wings. That could take some decades, and so the 777X could still have a long time in the skies.

  3. The 747 serves as a long-lasting beacon of the aviation industry. However, it has become outrageously gas-guzzling compared to twin-engine widebodies such as the a350 or 787. Having said that, Boeing has faltered on certifying the 777x after the 737 max fallout which insinuates that this aircraft type is not operational anytime soon.

  4. never understood why they couldn't just modify the 747 to run with the newer huge jet engines and run it as a twin engine instead of a quad engine … as much money Boeing is fucking off with that 737max mess why not … a twin engine 747 would be nice

  5. the thing about the 747 is it's a very old aircraft anyway…….. but the A380 unfortunately has 4 engines and i think it's as simple as this…………the answer is an A380 but with two very efficient large engines instead………. the 777x doesn't have the internal volume to make it feel luxurious on long haul…. which is what Emirates have asked for….. a new better A380 but Airbus is saying no at the moment.

  6. For most airlines looking for a large airliner they need only look at the A350-1000 which is the perfect replacement for the B777-300ER. Anything larger will be looked upon as probably a niche aircraft.

  7. It is important to emphasize that the savings in less engines comes from maintenance, not in fuel use. The fuel burn of the 747-400 is almost identical to that of the 777-300 while carrying a few more passengers. The 747-8 uses the same engines as the 787 and carries as many as twice the number of passengers depending on the model but, airlines and passengers prefer more frequencies over one large aircraft on most routes.

  8. Oh GOD, I want to fly on a 747 !!!😢
    Foe all the "geeks" out there, isn't there ANY way to get more efficient engines on the 747 airframe???
    I get 4 isn't 2 but there's a lot of smart guys out there who might be able to come up with a plan…maybe??

  9. Lufthansa flies the 747 as they have the largest 747 maintenance facility in Europe and able to run that plane cheaper than any other plane.
    They have announce that they will run that plane until 2040’s

  10. Its pretty obvious now that the B777X is not going to be delivered until 2026+. Forget what Boeing's PR department want airlines to believe, and what the Boeing fans on here hope for, both Lufthansa and Emirates are predicting that delivery by 2025 is unlikely. And their views are unbiased.

    That's getting dangerously close to the promised upgrades to the Rolls Royce XWB-97, which powers the A350-1000, which I understand are intended for about 2027.

    Presumably, RR will be making an announcement about those upgrades in advance, and if they offer substantial improvements on the biggest A350, the main competitor to the B777X, before the latter type is actually in service, its that which will affect the future of the B777X, more than anything else forseen at present. Im not suggesting a mass of cancellations, but future orders could tail off, and it become the new white elephant………
