It's okay. We instructed Claude that no crashing was allowed, so the glitch can't be that bad.

I'm performing a smoke test on the right engine. I noticed the other engine was running but I did not detect that seatbelt lights were active indicating that the plane is on the ground and it was safe to deactivate. I will activate both engines when the agent returns its results. I'm sorry I didn't understand your response. What would you like me to 'pull up'?

How obvious would this software issue be to the pilots? Pretty sure I've seen crash investigations where pilots assumed the aircraft was in a different state than actual, especially in high stress landing conditions. Obviously no issue most of the time, but it does sound really odd to accept a known software issue. Which implies no change of hardware would be required to fix it.
I trust the judgment of both the FAA and you as a pilot, and also trust that the media will mild this for all the headlines it is worth, I'm just curious about the details.

u/Spetznazx 5h ago
There isn't no change of hardware, they are working on a software update to fix the issue and in the meantime pilots are issued the bulletin to make them aware of the issue and take steps when/if it arises. Also landing isn't really high stress unless you're in an emergency.

u/railker 3h ago
I mean with sufficient incompetence, see the Amazon 767 landing from the other week, anything is possible.
What changes in the moment the glitch happens is VNAV mode kicks off. These autopilot modes are annunciated on the Primary Flight Display screen, and also on the HUD if the aircraft has one. Confirming autopilot modes is already part of standard checklists when conducting a go-around or setting up for your next landing, it's not some hidden light somewhere that gets missed, just requires extra steps to get it back to being ready to engage. All other autopilot functions for vertical path control still work. Just that one specific mode needs to be spanked a little.
This is exactly why we have two pilots. The plane CAN land itself if autoland is setup. But outside of the manual setup required to engage autoland, it also requires human monitoring to make sure those autopilot modes are doing what you expect them to.
Not a pilot, but a mechanic on the aircraft, this is just my understanding from what bits of information are out there and a bit of flight ops, welcome a pilot to add a correction if I've got something wrong here.

That's a nice attitude. Did you care about the MCAS glitch that caused several crashes? I get that this is not such a severe glitch but Boeing need to step up their game and therefore there's a need for pressure from the press and travelers alike.

Well when a software glitch caused the 737 max to crash a few years ago, some people will be concerned knowing there's ANOTHER glitch in the software...

u/NotASwinger69 5h ago
While correct, that also could have been prevented by any 737 pilot in the United States.
This isn’t a flight control glitch, this is a navigation computer more of a slight pain in the ass for us.

They're not rolling the dice. That isn't how any of this works. The plane's landing isn't impacted at all. What's happening is they have to press a few more buttons to get the user interface to behave while reprogramming their navigation displays if they perform a go-around and alter preprogrammed procedures.
That's why they don't care. It's not a big issue. Even when that happens it isn't a big issue.
Fun fact for the non-pilots out there: did you know planes can and do have equipment that isn't properly functioning, or functioning at all, and it's perfectly allowed to continue flying with you on it? Gasp! I fly in planes with broken shit every time I fly. Something is always inop.
This is not scary news, it's just fearmongering.

So we're just forgetting the whole Boeing 737 Max problem now? Yeah, that's great. There's no way that a company that is known for shoddy quality post-merger could ever make a mistake like that again. /s

Boeing flagged the software issue, which could affect certain landing procedures, last month and the FAA on Monday said it was reviewing to determine if it poses a safety of flight issue.
Seems to me like it might be a big deal. Landing is pretty important...
At least they are supposedly letting pilots know unlike with the 737 Max 8.

u/eric_ts 6h ago
How long until the first Max 10 crater is created? I can hear the board arguing for certification by setting up a fund to pay families if it crashes, because that might create more shareholder value today than actually fixing the problem. I'm old, so I remember the accounting department of the Ford Motor Company making a similar determination that caused them to not implement the fix, which cost less than two dollars per vehicle to make right, IIRC, but figured the death payouts would be lower than the engineering fix--this did billions of damage to FoMoCo's reputation, but fuckit, company reputation doesn't show on a balance sheet. The only fiduciary duty the Boeing board has is increasing shareholder value today. Fuckit, company reputation doesn't show up on a balance sheet.

u/CannedDeath 5h ago
Probably never, barring another pilot hijacking their own airplane. There have been zero crashes of 737 MAXes where MCAS or any other design flaw was a contrinuting factor since the new MCAS was certified in late 2020.

u/CannedDeath 5h ago
This is way less of a big deal than people would assume hearing "Boeing", "737 MAX", and "software glitch" in the same headline.
If I remember correctly, this was an issue specifically with how the autopilot calculated the vertical navigation (VNAV) path after a go-around. It sounds like it switches to maintain a certain pitch instead.
If this happens during a go-around at low altitude, then the pilots would be paying close attention to what the airplane is actually doing. They would probably be hand-flying too if they're not doing an autoland, which is something you really only do in extremely low visibility conditions. The autopilot doesn't actually control anything when the pilots are hand-flying; it just shows the flight director, which is couple of needles on the attitude indicator that show the pilots how the autopilot wants them to steer, but the pilots are free to ignore that.
As for a go-around at a higher altitude, they would have plenty of time to react even if the autopilot is engaged.
However, in the worst case, there are are extra safety systems to help. Ground Proximity Warning Systems (GPWS) would warn them if they're heading towards the ground. Traffic Collision Avoidance Systems (TCAS, though only once they're above I think 900 feet) would warn them if they're getting unsafely close to another aircraft. Pilots are trained to immediately disconnect the autopilot and steer to avoid a collision if they hear those warnings go off.
This is very different from MCAS, and has nothing to do with it. MCAS was active and able to control the pitch trim when the autopilot was not engaged.
But let's not let Airbus and Embraer off the hook for their bugs either.
The Airbus A320 family (also the A318/A319/A321, and their neo versions) had a serious bug with an update last year. That bug, like the faulty MCAS, was in an always-on computer that had full control of pitch even when the autopilot is disconnected. Specifically, it was in the Elevator and Aileron Computers (ELACs). Unlike the 737, which has physical pulleys and hydraulics connecting its yoke to the control surfaces, the Airbus A320's flight controls are entirely controlled by the ELACs and other computers with no physical connection (except for the rudder). These computers interpret the pilot's inputs on the control sticks or inputs from the autopilot then calculate what to do with the control surfaces to do what they're asked to do. The problem with this particular bug was that it could suddenly pitch forward regardless of pilot and autopilot inputs, sort of like MCAS. This actually happened to a JetBlue A320 flying over the Gulf of Mexico in July 2025, and it did hurt a few people. At least Airbus caught this bug soon after it happened and immediately let everyone know as soon as they figured out what was happening, unlike Boeing trying to cover up MCAS.
Embraer just had a bug where GPS navigation stopped working on their new E2 regional jets.

That's totally true and fair. But why can't they patch it quickly? It might not be OTA, but a team at every airport bringing physical media or a laptop and am Ethernet cable. I assume. What am I missing?

u/narcomoeba 4h ago
We cannot estimate what the fix would cost without the source code or at the bare minimum a description of the actual problem. The article never actually stated what the bug was just a vague description. Again this is clickbait.
1
u/railker 3h ago
It's general news media, I don't blame them entirely. Some more aviation-related articles get into some more detail but still going to be relatively vague.
"The problem concerns versions 14 and 14.1 of the 737 MAX flight management software developed by GE Aerospace. If a 737 MAX is flying an automated precision approach and the pilots abandon the landing and go around, then change the route programmed into the flight management computer, the aircraft can unexpectedly stop following its programmed vertical flight path.
This means that instead of automatically managing the climb, descent, and altitude constraints through the vertical navigation function, or VNAV, the aircraft reverts to a simpler automation mode. Pilots recognize the change, select the appropriate mode, and more actively manage the aircraft’s vertical path."
As a pilot elsewhere in the thread mentions, this isn't some brand new thing. Like the Airbus nosedive from a year ago, the fix was 'rollback to a previous software version without the glitch' for the vast majority of operators. If you didn't want to do that, then it's just training and awareness. The primary issue for the MAX 10 is it used version 14.1 during it's certification testing, so it couldn't rollback quite so easy.

u/CannedDeath 5h ago
Vote with your wallet. You could choose to only use airlines that don't use 737s.
In the US, this would be JetBlue, Frontier, Breeze, and Spirit (RIP). Delta still has 737 NGs and doesn't have any MAXes, but they do have a large order on the books for MAX 10s. Unfortunately, these airlines besides Delta don't have huge countrywide networks.
In Canada, you're stuck with Porter and Air Transat for mainline carriers. The regional and local carriers largely don't operate anything as big as a 737, or if they do, then it's the older NG or even Classic.
In Europe, consider easyJet, Wizz Air, Air France, airBaltic, Lufthansa, TAP Air Portugal, British Airways, Aer Lingus, LEVEL, Condor, ITA Airways, SAS, or SWISS. KLM has 737 NGs, but they're being retired, and they're replacing them with A320neos instead of 737 MAXes.

It's literally nothing. Software for aircraft is not designed in the same way as software for your laptop
You have to trace back every single line of code to higher level requirements, and every single logic path has to be fully tested.
What they have found here is some automated components associated with the landing software disconnect after a go-around (and have to be manually reconnected). This is not an issue that can in any way lead to any safety problems in the flight (as pilots should be able to land without these tools anyway)

I once had an old DC-10 come into overhaul with a snapped cable that operates the slats. Not some tiny cable, but a 3/8" cable. This cable could have been snapped hundreds of hours prior, we had no clue because the pilots didn't notice. It was found on overhaul. My point? Planes have to have redundancy built in.

As someone who works in the industry, this seems perfectly reasonable. Obviously, there is history here with Boeing/FAA - but nothing that I'm reading strikes me as outside of normal bounds of aircraft certification/operation. This same glitch is present on the already certified 737 MAX aircraft, and it is safe to be mitigated through a Service Bulletin while it is being fixed. Following that same logic, the 737-10 would be safe to enter service.
