Power Outage Strands Thousands at US Airport. 600 Flights Cancelled (cnn.com)

An anonymous reader quotes CNN: A power outage at the world's busiest airport left thousands of passengers stranded in dark terminals and in planes sitting on the tarmac, amid a nationwide ground stop. Incoming and outgoing flights at Atlanta's Hartsfield-Jackson International Airport were halted indefinitely as crews worked to restore power, leading to hundreds of flight delays and cancellations. Atlanta is the heart of the US air transport system, and what happens there has the potential to ripple through the country.

More than 600 flights to and from Atlanta have been canceled, including 350 departures, according to Flightradar24... Flights headed to Atlanta are being held on the ground at their departure airport. Inbound flights to Atlanta are being diverted, US Customs and Border Protection said. Departures from the airport are delayed because electronic equipment is not working in the terminals, the FAA said. The cause of the incident is under investigation.

Some people stranded in the dark terminals used their cellphones as flashlights, one passenger told CNN. "There were a few emergency lights on, but it was really dark -- felt totally apocalyptic."

    It seems odd than an airport is so unprepared for a power outage. I'd have thought they would have enough backup generators to run essential systems. As far as fuel goes, jet fuel would likely run in at least some diesel generators.

    Sure you have to divide up the circuits so you can run essential systems, or go around and turn a bunch of stuff off. You'd need emergency lighting 24/7 at minimum and at least all the computers and security equipment.

    Sure that level of redundancy is not cheap, but in a national emergency we need air travel to work. Whatever the issue is, it needs fixed.

      Essential means the tower, ILS beacons, runway lights, and radios, so planes can take off and land without crashing. All else is optional.

      Simple solution. The government will prohibit the word 'power-outage' and presto, no problemo.

      That's the absolutely essential. Ideally though, they could also keep enough systems running to continue moving people through. That would be computer terminals, adequate emergency lighting, baggage handling, etc. While highly arguable, I suppose TSA would claim their scanners are essential for as well.

      They certainly have backup power for critical systems like air traffic but remember that an airport is basically a city. 275,000 people a day pass through that airport. The eleven different four-car trains there carry 200,000 people each day. The terminal is 6.8 million square feet. Just to keep some lights on so people don't panic requires a ton of backup power. Providing power for all the baggage handling, runway lights, and all other systems is a HUGE ask. Powering it during normal times likely takes damn near its own power plant. Running it on backup power would an insane requirement.

      We did up until recently have a robust power generation capacity, but it lacked sufficient power to run the automated passenger immobilization & compression system required to load the next generation of aircraft (late 2019 and beyond). There are also no generating systems on the market which are capable of powering the new equipment, so it would serve no purpose beyond keeping the lights and computers running. If primary power shuts down, we lose the ability to load passenger-bearing aircraft and will have to shutdown anyway, so we might as well slightly reduce our operating expenses.

      Anyway, the vacated space where the backup generators were previously located will be re-purposed for additional luggage mis-routing capacity, as well as for disregarding the complaints of some of our more vocal customers.

      It can be done pretty easily, it just costs money. Airports like Honolulu have on-site backup generation, but not sure what percentage of the load it covers— my guess would be about 65%.

      For Atlanta the load should be around 35-40MW. 5-6 Turbines would cover it, but it would be about $20 million, and then you need to make sure your common points of failure with utility power are manageable, which would likely double the cost.

      They don't need backup generators for this kind of fault. Just a second main power feed from the grid. There's plenty of power in the city of Atlanta, just no way to get it to the airport.

      It isn't as far off as you might imagine though. The Australian Tesla battery plant as an example could give the whole airport ~3 hours of ride-through. Break it up so you have backup at each substation and you are in pretty good shape.

    A backup system limits the common points of failure with the primary system. While there are plenty of airports with co-generation plants that can backfeed the primary utility circuits supporting the airport, this is generally not considered a backup system. (LAX has about 20MW of generation in their central plant, but IIRC it doesn't have black-start capability, as an example.)

    Airports have the benefit of being big; generally, a properly designed system will maintain reduced operations under failure conditions. It won't eliminate an incident, but it can drastically reduce the impact of a major problem. You can sacrifice a concourse, but you limit the impact on other concourses so you can keep moving in the degraded state.

  10. 2nd major delay in as many weeks... by Drakonblayde · · Score: 4, Informative

    I was stuck at Hartsfield for 11 hours last week thanks to the snowstorm that hit Atlanta.

    The snow wasn't all that bad. The problem was that the planes had to be deiced before they could take off. Hartsfield only has 4 de-icing pads. It takes about 15 to 20 minutes to de-ice a regional jet, about an hour to de-ice one of the heavies. I was listening to ground control pretty much the entire time (thank you LiveATC app), and it was a mess. Pilots weren't responding to directions properly, creating an even bigger traffic jam. There was no clear order in which the planes were going to be de-iced, it was decided by the airlines based on priority of flight and the order wasnt always communicated to the ground control tower, so the ground controllers couldn't even line them up in the order they were going to be de-iced. This combined with the lack of speed to de-ice the planes led to a number of flights having to return to the gate in order to avoid tripping over the 3 hour rule. This also resulted in other flights not pushing back from the gates, since once they close that cabin door, the 3 hour countdown begins. Incoming flights were delayed or cancelled because there weren't gates open for their passengers, and since inbound flights were getting cancelled, outbound flights were as well since the planes that would be servicing those outbound flights were no longer inbound.

    It became apparent to me that this wasn't a weather problem. It was a major inefficiency in airline operations. Yeah, I know, it's Georgia (I lived in the Atlanta metro area for over 2 decades) and it doesn't snow that often, but you'd think the busiest airport in the US would be better equipped to handle something like de-icing planes, especially given the ripple effect that disruptions at Hartsfield has on not just US transport, but globally as well. The international disruption isn't that bad, those flights can be diverted pretty easily, but domestic flight? There aren't any nearby airports that are even close to capable of handling the load that Hartsfield does.

    And then today there's a major power outage that disrupts one of the busiest travel weekends of the year.

    Maybe now they'll pay attention and revamp Hartsfield's operations so that it doesn't fuck everyone plans up.

    If one fire can damage the backup systems then they weren't really backup systems now were they?
