I worked on modernization in the FAA specifically around digitizing NOTAMs.
I would urge you not to consider this modernization from the perspective you may be familiar, as someone who may work on the bleeding edge and sometimes sees a lack of caution from engineers pushing for change.
The FAAs safety risk management is built around a rigorous process, but that is also a massive slowdown to reasonable progress.
One of the eng I worked with was 80+ years old and just didnt want to retire. He did not understand modern systems at all and the risks we were looking at were not (imo) realistically balanced.
I get the idea that the current administration is pushing safety to the side, but there is another risk where safety becomes a blocker to reasonable change.
When I left that work (more than 15 years ago) it was clearly a blocker.

In one role, I worked on writing software for drones.
That very rigorous process was very reassurring to me. Reasonable progress was absolutely occurring.
> One of the eng I worked with was 80+ years old and just didnt want to retire. He did not understand modern systems at all and the risks we were looking at were not (imo) realistically balanced.
What kind of risks were you looking at with what kinds of balances, if you're able to share?
today at 5:28 PM
I liked the process but i didnt see a counter pressure to the SRM process. It often became a hard blocker.
The SRM board knew the legacy system but much less the modern one. Its hard to compare safety when you only clearly understand one systems safeguards.
I appreciate the process being there but at the time it felt much more like (some) people protecting their jobs than the public.
The risks I felt were overblown (iirc) were around likelihood of catastrophic failure in the system.
I actually loved the overall process and it informed how I look at software, it was the application of the process that bothered me.

The SV (silicon valley) motto of fail fast and break things accelerated evolution of software design systems. Can you imagine what would happen if people were hesitant to use Git works because a merge could break something? Lol.
But this kind of precaution is quite necessary in the development of AI systems. Current regulations have turned a blind eye to accelerate software and AI progress. Now we have security bugs and misalignments, and we will have AI misalignments as well.
Knowing how computing landscape has changed in SV, I can't imagine modern day SV helping fix FAA systems. Alternatively we could go with multiple incarnations of the same system, being battle tested and proven with independent concurrences, alongside current FAA system. Yeah, it is a boatload of money, and probably wasting 90 percent of it in redundancy.

in your opinion, what would be the most intellectually honest comparison? aviation in Europe or China? it would seem that a lot of shortages / pressures are artificial, in the sense that they are created purposefully by a political process.
we can look at this more holistically than a specific IT project. like in china, which is not a place i want to live, it is still valid to say, their process of steamrolling past local interests means that airport expansion and transit to new airports can be built quickly, which helps meet demand for air travel better than working at the absolute limits of safety and efficiency tradeoffs.
local control in the US infests everything. it causes airports to be too small, guilds to grow too slowly, it opposes infrastructure, it makes politicians too vulnerable and too weak to make changes that upset minor but powerful real estate interests.
so in one POV, safety is a blocker to reasonable change, but everywhere else in the world, they just increase capacity, and the huge stresses on safety limits are reduced.

More information needed. Was this a sneakernet? No one thought of replacing with a floppy emulator and SD cards? All of the data can fit into 1.44MB?
If the last one is true, devs take note. If FAA can rely on slow, small storage for safety critical applications, you probably can reduce the resource requirements for your app and improve your customers’ experience and extend the life of their hardware.

> devs take note
There’s been an incredible expansion of computer hardware and networking in every dimension since the heyday of the floppy. And the floppy itself was a huge step up from technology of even a few years prior.
Your comment could have been made in any year since 1950, and it would have been both correct and irrelevant outside the areas most resistant to hardware upgrades. FAA is conservative, and should be, but the rest of us have supercomputers in our pockets.
Have software developers abused the hardware capabilities they have been granted? Of course they have. I’d love to see some care put into that. But beyond the basics, hand-twiddled hyperoptimizations are now an exercise for craftspeople. Or…AI?
today at 4:41 PM
According to this article, it's far worse than that: eight inch floppy disks! Capacity might be as much as 1.2MB per disk, but probably less. https://simpleflying.com/americas-atc-floppy-disks-12-billio...

At the very least, physical media is airgapped. Floppies still aren't a good choice though, since they develop bad sectors so easily.
today at 5:28 PM
Do they? or is it low quality media? Rather than judging old tech bad, new tech good we should look at the requirements and tradeoffs. The failure modes of the new replacement system look more catastrophic to me, relying on cloud infra and internet links.
I can't find information about how the disks are used specifically, how often they are read, written, what data they are used for, if they can be replaced by floppy emulators, etc.
12 billion for a new system that might not actually be an improvement is a lot of money.
today at 5:16 PM
> they develop bad sectors so easily
I never had a bad sector on 5.25-inch Double-sided, Double-Density (360K) diskettes, but I did all the time with 3.5-inch HD ones (1.44MB). I'm seeing some references to 8-inch and some to 3.5-inch disks used in the FAA, but I'm not sure what source has reliable information about that.

Micro-services with docker running out of a kubernetes compliant blockchain with somewhere some "AI" added in the mix. I guess this news is more for PR than anything else because I don't see how the replacement of 69% of copper wire is meaningful in any way. What copper wires? Where? Is it because you removed landlines and replaced with voip?

I have a bad feeling that this is not going to end well. Especially given that this administration is... Rather incompetent. I hope that safety is like number one on their list of priorities but somehow I doubt it
today at 4:28 PM
I would rather things be done "incompetently" than nothing being done at all.

> I would rather things be done "incompetently" than nothing being done at all.
Engineers of today aren't better than engineers of yesterday, they just have access to new technology (and new footguns).
I'd rather have a well-designed legacy system that does the job well, than an incompetently designed "modernized" system that doesn't.
today at 5:32 PM
> Engineers of today aren't better than engineers of yesterday
Our ability to wield technology has gone up, while our ability to engineer and understand that technology (as a whole) has gone down.
Age should be the most suspect of arguments against the design of a system. Enumerate specifically its flaws and not just that it is old. System design doesn't wear out, it is abstract, like mathematics.
today at 4:42 PM
Nothing being done at all means the system continues working as it is. Something being done incompetently means more people die.

I agree, nothing says poor priorities like upgrading the air traffic control system. It removes the opportunity for graft, only supports the monied elite who can afford to fly and don't care about climate change, and diminishes the opportunities for crises to exploit.
Instead, the United States government should have continued the policies and values that led to Next Gen, ERAM, STARS, and AAS.
today at 4:39 PM
what do you mean. a lot of poor people fly as well. I won't would even risk to say that poor people fly more often. For example migrant workers flying lets say Bulgaria-Ireland every few months

I don't want the FAA to make changes at "lightning speed" or "rapidly moving to make upgrades" or "record pace". Safety must be further down the list for these guys.
today at 3:31 PM
Using outdated computer systems with aging storage media is a safety issue.
today at 3:54 PM
No, it isn't. This is time tested process. Find me any flight that had to land or crashed because the floppy disk was broken.
today at 4:08 PM
I've worked on systems this decade that still relied on floppy disks. It's getting harder and harder for them to operate because the disks are getting rarer, as are the drives. And often the essential component is not the disk itself. There are some other computers in the system that cannot be upgraded to any more recent device, systems from the 1980s and 1990s that force them to continue using a floppy disk.
If it was just two modern computers and transferring data between them, the floppy disk would have been dropped in a heartbeat. But it's the old computers still in the critical path that are holding everything back. And those are really hard to maintain. Last year we phased out a system that was dependent on computers from the mid-1990s, getting replacement parts was practically impossible, they mostly just don't exist. You'd buy old systems off ebay and hope that they had enough working parts to scavenge, and the right working parts.
EDIT: Light editing because I had some extra words.
today at 4:56 PM
It's both time tested and at risk of ripping at the seams. Floppy disks and the mechanisms still wear. And because neither are still made, the chances of a zero population scenario happening is greater every year.
It's better to test a replacement while you still have the time, than to risk rushing something else.
today at 3:40 PM
Replacing them with cloud-based systems (if this is the "streamlined, 21st-century system") is a safety issue as well. I hope they are not.
today at 4:41 PM
Fortunately the choice isn't between 1980s hardware with floppy disk requirements and rented servers in someone else's building. There are a lot of options in between those two.

I love the idea that the headline suggest that Sean Duffy and his family at the completion of their multi-month road trip going on another one.
This one, where the tour stops are ATC data buildings, where they only stop in to swap out floppy disks for USB drives.

They are signalling Trumps involvement so I will assume it must be another vanity project he wants to stamp his name on. I look forward to hundreds of grounded planes due to cloud based weather reporting not being available because of a borked server update or misconfigured wifi adapter.

why is this "historic"? the thirst for this admin to use the most bombastic language possible is so tiring.
Just... modernize the thing already. thats your job. It's not impressive that you did this. You're supposed to do this. You dont get extra kudos for doing the thing you signed up to do...
and dont forget to put Trump's name at the beginning. Or he might get cranky
today at 3:45 PM
Everything they try to spin positively has to be 'historic' because:
1. The party leader is a fragile, dying narcissist who is desperate for his name to be attached to anything other than the misery he's inflicted upon the world.
2. Their _actual_ historic achievements are all war crimes, human rights violations, and policy changes that would terrify their average supporter if they actually understood the long-term consequences.
today at 3:53 PM
It’s historic because no else has done it in the last 40+ years. Doesn’t make it a big deal, but it’s still a big change.
today at 4:08 PM
It is a big deal if you fly :)
The inability to keep the air traffic control system effective and maintainable is far more embarrassing than the inability to update the IRS software or build a high-speed rail.
