FAA To Eliminate Floppy Disks Used In Air Traffic Control Systems (tomshardware.com) 135

An anonymous reader quotes a report from Tom's Hardware: The head of the Federal Aviation Administration just outlined an ambitious goal to upgrade the U.S.'s air traffic control (ATC) system and bring it into the 21st century. According to NPR, most ATC towers and other facilities today feel like they're stuck in the 20th century, with controllers using paper strips and floppy disks to transfer data, while their computers run Windows 95. While this likely saved them from the disastrous CrowdStrike outage that had a massive global impact, their age is a major risk to the nation's critical infrastructure, with the FAA itself saying that the current state of its hardware is unsustainable.

"The whole idea is to replace the system. No more floppy disks or paper strips," acting FAA administrator Chris Rocheleau told the House Appropriations Committee last Wednesday. Transportation Secretary Sean Duffy also said earlier this week," This is the most important infrastructure project that we've had in this country for decades. Everyone agrees -- this is non-partisan. Everyone knows we have to do it." The aviation industry put up a coalition pushing for ATC modernization called Modern Skies, and it even ran an ad telling us that ATC is still using floppy disks and several older technologies to keep our skies safe. [...]

Currently, the White House hasn't said what this update will cost. The FAA has already put out a Request For Information to gather data from companies willing to take on the challenge of upgrading the entire system. It also announced several 'Industry Days' so companies can pitch their tech and ideas to the Transportation Department. Duffy said that the Transportation Department aims to complete the project within four years. However, industry experts say this timeline is unrealistic. No matter how long it takes, it's high time that the FAA upgrades the U.S.'s ATC system today after decades of neglect.

          Um, while it's true that all the Republican presidents since the 1970s have failed to update the system, there have also been a number of Democrat presidents in that time period, and they've done just as little as the republicans about it.

          There's quite a few things like this. You have a system in place, which is of critical importance and while generally everyone takes for granted that it always works there would be severe problems if it stopped working. So updating it is potentially expensive and difficult, and there's a risk something will fail during the update with catastrophic consequences, while just leaving it alone costs nothing, and everything still works as expected. So the politicians just take the easy option.

          Where I live there are many things like this, public infrastructure including railways, public utilities, industrial software, banking systems, software that runs hospital equipment etc etc. From what I've heard it's very similar in most other places in Europe and probably in the world. While things are working they're just left alone, up until they stop working or are about to, at which point everyone starts running around in panic. See Y2K for example. So it's a good thing they're at least updating this system now.

      The "safe" way to do it is leave the old system in place and running, and install the new system next to it. Let them both run simultaneously for an extended period of time, with the old system still in charge and the new system running and computing results, but its results aren't actually controlling anything; they are only recorded to verify that its behavior is always the same as the old system given the same inputs.

      Once you've thoroughly tested and debugged the behavior of the new system that way, you flip the switch so that now the new system is in control and the old system is merely having its results recorded. Let the system run that way for a period of time; if anything goes wrong you can always flip the switch back again. If nothing goes wrong, you can either leave the old system in place as an emergency backup (for as long as it lasts), or decommission it.

    • The FAA is aware of digital systems to replace paper strips. The problem is funding and the FAA has not mandated digital systems because some airports have no other system yet.
  • Maybe this could be the spectacular failure that finally pushes IT to some level of actual quality. Windows for mission-critical things? The mind boggles...

    • When we hear of things like this, the main reason they still exist is that no replacement has been installed. Often times that is because no replacement has been funded. Infrastructure upgrades are unlikely to get funded over new and shiny things.
  • Let it crash a few planes to make the public aware of how unreliable AI is, and see the bubble burst.

  • While this likely saved them from the disastrous CrowdStrike outage that had a massive global impact

    Exactly none of those endpoint security packages belong on anything safety critical.

    Their remote management and monitoring features present single point attack surface, pop the management server and you likely have enough C&C to at least DOS-condition all the clients.

    They potential break operations like filesystem access in potentially surprising ways that are difficult or impossible to do good defensive programing and error handling around.

    They are only effective if updated frequently which means your

    • 100% correct.

      I work on systems that end up on commercial aircraft. They are not flight-critical systems, but we still act like they are and mandate that updates only happen when the operator wants them, even if we release them whenever ready. They get to push the button. And in the meantime, every time the airplane is on the ground, it automatically backs up the configuration data off the aircraft, and that backup is verified before putting it into storage. Nobody has any form of privileges on the syste

  • Oddly, I like simple, reliable things. As some who like to inform people in Silicon Valley that their brake lights don't work, I see no fewer new cars with bad tail lights--likely because of the complexity or such things as Canbus systems. So, while the floppies are slow, they are likely part of something otherwise more reliable. Flash drives go bad, but we will not hear about them going bad.
    • I'm not saying that the replacement won't be worse, but floppy disks were always notorious for losing data and generally being unreliable. Despite SD cards having a notorious fault where leaving them unused for a year or so can result in data loss, I've lost far less data from SD cards than I ever did floppies.

      I think there can be a happy medium here where the replacement is airgapped and based upon reliable, serviceable, modern hardware, the question is whether that's what's going to happen.
