With the end of the 747, A340 and A380 approaching are we approaching a world with only twins?

On the business jet side, Falcon production line by Dassault Aviation will continue to deliver three-engined models like Falcon 7X and 8X for some time to come.

Militaries will not give up their quads easily, neither turboprops (A400 in current production) nor jets (Russians revived Il-76 production)

So, there will be planes other than twins around. But getting to fly on one will be more tricky than just buying an airline ticket.

What do you mean approaching?

They will be around for at least another 30 years

Don't worry, the Il-96-400M will be a big success and pick up where the A380 and 747-8i failed. Delta will buy it to replace their aging fleet of transpac-incapable A350s and a.net will rejoice at the brilliance of Ed Bastian and Vladimir Putin will create an account to celebrate here with us.

You forgot to mention that while Delta will use it on the TPAC routes, TATL will be served by Baltia ;)

No, there are still heaps of 747s, MD-11s flying around. There will still be four engined jet aircraft flying around transporting freight.

You didn't specify passengers in particular.

Electrification of airplanes, if and when it happens, will likely, and interestingly, mean the multiplication of smaller motors around the airframe.

Smaller electric designs will probably boast many several smaller motors distributed around the wings and fuselage to reduce the current needed to any one motor and the overall weight as smaller motors are lighter, cheaper to run and easy to maintain. Their extreme reliability would probably largely mitigate the operational disruptions linked to the increased probability of motor failure in a multi-engine design.

It's not over yet for quads. Hell, we might see Sextas or Octas around one day and will miss the days of these beautiful twins and their big and noisy jets... Who knows. :wink2:
It won't be for a while, however.

Antonov 225 and the recently launched Stratolauncher are there to stay for a little bit longer.

Electric engines CAN sound cool though. I hope the first ones don't disappoint. Also, if Boom becomes reality, the current plan is for a trijet.

No.

There will be twin engine props around for a while yet :duck:

And single engine props. The OP think all those Cessnas (or Pipers, etc.) will just go away? :duck: . Even for commercial service you have C208s and PC-12.

Oh, and military will have plenty of non-twin jets. Just in the USAF you have F-35, which is single engine. Also, 8-engine B-52 will probably still be around when F-35 retires.

Apparently the Russians didn't get the memo.

748F's will be flying for decades to come...

Until BWBs come out, yes. Only the 748F line is going for commercial and that is on life support.

BWBs have an issue with engine out without a rudder that is solved by having 3 or 4 engines. Boeing's idea on engine pylons sort of gives mini rudders anyways.

I can imagine for regional jets we'll eventually be heading towards single engine jets. They already exist, such as the Cirrus Vision SF50. This is a business jet of course, but if it's possible on a small aircraft it's possible on a bit bigger as well. Of course for anything more than regional two engines will remain mandatory.

Quads are slowly on their way out. I know there are still a lot of them out there and some types are even still in production, but they'll be the last of their kind. One day the production of those types will end and whatever will replace them will have less engines. The next step is for the existing quads to be retired, which will take quite some more time but will eventually happen.

But like I said, even then we're not approaching a world with only twin engined jets. Twins will dominate long haul, but on short haul one engine will be enough.
