Maybe they should have bit the bullet and fully redesigned the 737. Presumably future engines will be bigger still, will they just tack them onto this old design as well? At the end of the day this is just a software fix.
That's EXACTLY what they didn't want to do.
Airbus was able to do the 320Neo without a redesign. They essentially slapped new engines on it and made tiny adjustments. Boom, fuel savings.
Boeing wanted to do the same. Their design didn't accommodate the bigger, more efficient engines they wanted. So they created a workaround.
Redesigning essentially means creating an entirely new aircraft, even if it looks similar. Requires a new type certification, which is a very lengthy process in itself. Requires pilot training for the new type rating. Possibly new simulators, and simulator time. Not all airlines even own simulators.
Airlines like Southwest use all 737s exactly because that makes pilots interchangeable(simplifies logistics and maintenance too, but mostly it's about pilots).
If I'm an airline and now you tell me my pilots need training, including expensive simulators, it's no longer the same aircraft(as in, not the same type rating). If it is not the same aircraft, that means I could choose any other aircraft. Such as these new Airbus models I've been hearing about...
See the problem? MCAS wasn't such a bad solution on paper, it's just that the implementation sucked. It should have required some minimal training (which is much better than a new type rating) but Boeing didn't even want that.
Note that Boeing had this problem ever since the 737 Classic (the second generation 737) was introduced, hence the non-circular engine inlets they've had for decades. This cost them efficiency, at the benefit of maintaining commonality with all its advantages.
Note that last I heard Airbus was planning a clean-sheet redesign for the A320neo's successor, targeting an early 2030s introduction into service. If you allow me to speculate for a moment, Airbus is in an interesting position now having the A220 in its family: it could easily stretch the A220 to be comparable in capacity to the A320, leaving an A320 family replacement to focus on the A321 and the smaller midsize market.
The A321XLR is already a huge success.
I'm not even clear what that fix boeing used to cover up this problem. The article didn't specify, that is a red flag.
The control mechanism caused the crashes, and control mechanisms can be fixed relatively easily.
The control mechanism existed to cover up a physical flaw then proceeded to be the cause of crashes itself.
If a control mechanism can easily be fixed... What was the exact fix? Literally tell me.
It makes the control curve slightly different, don't be so dramatic.
> If a control mechanism can easily be fixed... What was the exact fix? Literally tell me.
I'm not psychic, I can't tell you how they fixed it, but you can find a ton of people talking about how redundant sensors would have avoided the same issue. You could also have it be much more obvious when it's adjusting trim, because if the pilots were aware of what was happening they wouldn't have crashed either.
from your other comment> Saying the control mechanism crashed the plane and just fixing that is like saying you didn't put enough duct tape over the real problem.
Tape, and the equivalent of tape, is a valid solution to many problems if you have an expert analyze it.
I'm not being drastic, the plane has an unconventional control system built to hide a physical flaw that is never an actual physical property on planes designed from the ground up. The plane will literally stall:

It's well known boeing used a hack to avoid costs of redesign.
>Tape, and the equivalent of tape, is a valid solution to many problems if you have an expert analyze it.
The experts who killed 300 people analyzed the mcas and also built it. No one will get on a plane covered in duck tape no matter how many experts analyzed it.
>I'm not psychic, I can't tell you how they fixed it,
Makes sense that you're not psychic. Likely you went to google at some point and tried to find out what that fix was and likely you found nothing. That's a red flag, a huge one.
Being psychic is the only possible way you'll know what the engineers did to duct tape the whole design. At the very least this is something any wise man should know about before getting onto that plane.
> The experts who killed 300 people analyzed the mcas and also built it.
It could be fair to avoid all planes coming from those experts. But if you don't trust them to fix a single flaw, why in god's name do you trust them to design an entirely new plane? This is not a reason to push for a redesign.
> No one will get on a plane covered in duck tape no matter how many experts analyzed it.
Ever heard of speed tape?
Most people will either get on the plane when it's fixed, or they will never get on the plane. They're not going to care about the exact details.
> Likely you went to google at some point and tried to find out what that fix was and likely you found nothing. That's a red flag, a huge one.
Sure. Red flag. But a flag is far from conclusive.
> At the very least this is something any wise man should know about before getting onto that plane.
I'm wise enough to not play armchair plane engineer when my life is on the line. If I don't trust the process, then I'll wait for a certain number of flight hours instead. I'm not going to depend on my own ability to analyze plane design.
The locations of the engine and a plane flown without mcas will also cause the plane to crash.
The technical debt transferred over to the control mechanism and now all the engineers and people who worked on and funded the plane are responsible for killing over 300 people. These are peoples lives at stake. Fix the technical debt. Saying the control mechanism crashed the plane and just fixing that is like saying you didn't put enough duct tape over the real problem.
Don't Cover it up.
If I were the EU regulator, I would have forced them to... It's a great way to screw over Boeing (American) and boost sales for Airbus (EU), while having the fairly legit rationale that you no longer have confidence in the US regulator due to a long series of blunders, and you are not happy for a major new plane design to use a decades old type rating (and is therefore missing now-mandatory safety stuff).

Trade agreements are written to anticipate this sort of thing.
An expectation of a product creates a product. And a product (can) create(s) demand with or without that expectation.
Of course that won't happen as aerospace is such a strategic industry.
Multiple aviation projects have almost bankrupt Bombardier in recent history, so I don't really see them getting back into it. And it's hard to see what BAE Systems would get out of entering the commercial aviation market.
Um let's be serious. Hard no on those.
The even bigger problem is that our governments allow companies to get to these “too big to fail” states, and I myself am pretty tired of it. Every single time it is the consumer that pays, either literally or with their lives.
It can't be good for innovation or the consumer if a giant established player is getting preferential treatment.
You shouldn't be able to say "we followed all regulations" when people die and leave it at that. They should stop playing games and just design an aircraft.
Boeing planes are super safe from millions of flighthours and the learnings and failures from before. The older aircraft annealed into a state of safety and reliability from known-ness.
"fully redesigning," introduces a lot more risk.
Which you use to build off of.
It's why banks still run on mainframes despite trying (quite desperately) to get away from that.
The length of developing a fully new aircraft is too long considering the competition, assuming you aren’t particularly passionate about safety.
