> You suggest that we should sacrifice the rigor of pilot training to allow delivering planes without safety compromises

Describing this as "sacrifice the rigor of pilot training" is illegitimate. If someone is already certified on a similar plane, the training they need is really only on the difference between the planes.

> I think there’s absolutely no justification for safety compromise in this scenario - the new plane will pay for retraining costs in a slightly longer amount of time than it would’ve had retraining not been required — oh well.

The problem is that monetary costs are still safety costs. Now the new thing costs more and people choose alternatives that may be less safe. If new planes are more expensive then older planes that are more likely to suffer wear-based mechanical failures stay in service longer. If air travel costs more then more people drive.

Boeing obviously screwed this up, but we gave them the incentive to screw it up, and that's on us too.

> The real question to learn from this tragedy is not how can we make it slightly less expensive to produce a new air frame — it’s how can we ensure that safety is not allowed to be compromised during the design phase of new passenger aircraft in service of _truly_ minor cost savings

But that is how you do it. You figure out how to achieve the cost savings without compromising safety. There is no law of nature that says they're mutually exclusive, and without forcing them to be at odds there is no longer an incentive to choose the wrong one.

No WE didn't. THEY wanted to cut costs and it appears to me THEY cut corners to achieve it. This is like saying the professor made me cheat by making the exam artificially complicated and learning would have cost to much time.

[AnthonyMouse]

Yes WE did.

This isn't a game or a class. If you have rules that result in preventable deaths in actual reality then you have bad rules. Even when there is plenty of blame to go around.

Who is WE here? The general public who use the planes? The airlines who bought the planes?

The public and the airlines relied on the FAA. The FAA allowed boeing to self-cert. The FAA's job was safety. The FAA failed in that. It was their job and they didn't do it properly. It's the FAA at fault not some amorphous WE.

There was no American flight that crashed. The crashes were Ethiopian and Indonesian where the FAA has no jurisdiction.

> There was no American flight that crashed.

But that's not because 737 MAX aircraft flying in US airspace somehow didn't have the problem that caused the crashes. There has been plenty of coverage online of US pilots repeatedly filing reports with the FAA of "near miss" incidents in 737 MAX aircraft caused by the same problem.

[tempguy9999]

So the FAA certifies planes that fly in US airspace but does not certify planes that fly elsewhere, and cannot therefore be held accountable for crashes caused by defective aircraft in those non-US airspaces?

Are you seriously suggesting that?

[18pfsmt]

According to the HN guidelines, you are in violation because you have assumed bad faith on my part. I will not engage further with you, tempguy9999, you are not responding to my most obvious argument. Good day.

Training to fly two very similar planes can be more dangerous than flying to completely different ones.

For example, some marks of Spitfire had engines that spun in the opposite direction to the rest of them. The aircraft were otherwise similar.

If a pilot gunned the engine during the take-off roll, the torque reaction will cause it to swerve. The pilot can catch it with the rudder if they are expecting it. If the engine is spinning the wrong way, and the pilot inputs opposite rudder, the aircraft will wreck it's undercarriage and roll over on the runway.

Whilst training to fly any variant, when a pilot has experience in other variants is obviously going to be quick and easy, expecting them to swap back and forth between variants is also clearly unsafe.

The aircraft type rating is exactly difference training. You don't start from scratch just because a type certificate differs between two airplanes. The whole point is to require that difference training, and for it to be specifically laid out.

Whereas without that, what did Boeing do? They gave pilots an iPad for difference training, and kept them in the dark about the differences between 737 NG and 737 MAX. That was their choice. The lie of omission by manufacturers is the whole reason why we have type certifications in the first place.

You're talking about training for completely different planes. Type training is commonly multiple weeks long. What I'm suggesting is something intermediate for two variants of a plane that are much more alike than that ("subtype training"), so that it's hours or days rather than weeks because there aren't as many differences to cover between two 737 variants than between a 737 and a 787.

> Whereas without that, what did Boeing do? They gave pilots an iPad for difference training, and kept them in the dark about the differences between 737 NG and 737 MAX.

Right, exactly. So they have the tiers too far apart. There is too big a jump between "here's an iPad" and tens of hours of training over multiple weeks, so there's a need for something in between for smaller variations.

I'm not talking about completely different planes. If you have a Boeing 737 type rating, obtaining a 757/767 type rating is more expedient than it is for someone who has no prior Boeing 737 type rating.

Further the regulations say whether a type certificate is required, and what goes into it, is up to the administrator. It's not strictly defined. You can in in effect have subtype ratings.

FAA regulations are very much dependent on delegating authority rather than detailing every nitpicky thing. They really aren't that complicated.

Aren't the 737 and the 757/767 completely different planes? Isn't the difference between a 737 NG and a 737 MAX a lot smaller than the difference between a 737 NG and a 767?

> Further the regulations say whether a type certificate is required, and what goes into it, is up to the administrator. It's not strictly defined. You can in in effect have subtype ratings.

It's not surprising that the regulators have that level of discretion, but that only helps if it's expected they'll use it like that, which seems contrary to what Boeing did expect given their apparent aversion to it.

[cmurf]

>Aren't the 737 and the 757/767 completely different planes?

No. But then, given your questions thus far, we clearly don't have a common frame of reference, so I don't really know what you mean by completely different. They are not 100% different, that's for sure.

Consider this: the difference between a 737 NG and MAX is smaller than the difference between a 757 and 767. And yet the 757/767 share a single type rating. They were designed at the same time and have nearly identical cockpit layouts. And guess what, the Airbus 320 and 340 share the same type certificate as well, they're more different from each other than the 757 and 767 are to each other. But the two Airbus's also have the same cockpit layout, control systems, and software abstraction such that in normal flight they pretty much behave the same (obviously ground operations are different, they are rather substantially differently sized).

A "subtype" is just not applicable in this discussion. Any completely redesigned airplane from Boeing, in lieu of the 737 MAX, no matter its size, is going to so radically depart from any other airplane's flight characteristics and cockpit layout, that it would absolutely end up with its own type certificate. You can't design a new airplane model, and shove in the cockpit from a 737 NG. You can't and you wouldn't want to.

They dropped the ball. And the instant the Airbus 320neo was announced, Boeing was shown to have gotten caught with their pants down, and that has nothing at all to do with the regulatory paradigm.
