If you’ve flown recently and noticed United Airlines flights grind to a halt, you’re not the only one. The airline suspended all of its mainline flights for a few days last week, confusing and upsetting passengers. Let’s look a bit deeper into just what happened and why the brief suspension occurred.
A sudden sause
Tuesday night, September 23, United Airlines asked the Federal Aviation Administration (FAA) to ground all traffic temporarily at American and Canadian airports. The ground stop lasted approximately one hour and caused flight delays to customers across the country.
A United spokesperson stated, “United experienced a temporary connectivity issue late Tuesday evening Central time, but has resumed normal operation since.” I.e., it was a technical malfunction that forced the airline company to take necessary measures for coordination and safety.
Interestingly sufficient, the ground stop wasn’t yet widely reported on United’s news streams or social sites the next day. That is what occurs with brief interruptions—they get sorted so fast that flying passengers may possibly not be aware until flying is fairly delayed.
Not the first time
This is not the first unscheduled layover for United. At the beginning of this month in August, there was a technical fault that grounded flights at some of the hub airports like Newark, Denver, Houston, and Chicago. The outage caused a sea of delays, and passengers waited in lines or remained stranded on tarmacs.
Luckily in that situation, the problem was addressed within a few hours. While infuriating, such transient disruptions are generally temporary in nature, and flights return to their routine schedule when technical problems are resolved.
What a ground stop technically means
You can wonder: what actually happenss when flights are “grounded”? A ground stop is defined by the FAA as an air traffic management program that holds up some flights on the ground until the issue is resolved.
Ground stops can be caused by a wide variety of reasons:
- Airport-specific problems: Such as a closed runway or local weather.
- Airspace restrictions: Temporary limitations in the airspace over certain areas.
- Failure based on technology or equipment: These include instances like United’s.
The issue is that ground stops are safety measures. They ground airplanes in case something occurs that can affect operations, air traffic control, or passengers’ safety.
Why technology matters
Airlines operate aircraft, communicate with airports, and handle crews using sophisticated computer systems. A single small connectivity issue with the systems can propagate across the network and lead to delays and shutdowns.
For United, the overnight ground stop was due to a “connectivity issue.” Although it hasn’t specified the exact technical issues, the carrier is reminding us of how much contemporary air travel depends on technology. One bug can affect hundreds of flights for relatively little time.
How airlines and the FAA respond
When something is amiss, airlines act fast. Airlines work with the FAA to keep flying safely, and occasionally that involves stopping departures for a bit. When it’s fixed, flights resume regular flight times.
Travellers are delayed, have their flights cancelled, or have their flight times adjusted. United and other carriers generally aim to get planes aloft as soon as possible, as well as to inform passengers.
What travellers should know?
For travelers, a ground stop can be stressful, but it’s not dangerous. It’s simply a precaution to ensure that every flight is safe and properly coordinated. If you’re flying and a ground stop happens:
- Stay patient and keep checking updates from the airline.
- Follow instructions from airline staff at the airport.
- Expect potential delays, but know the airline and FAA are working to resolve the issue quickly.
The takeaway
United’s ground halt last evening was a short one, only an hour or so, and it was because of a technical connectivity issue. Not pleasant for travelers, certainly, but this type of event is all in the name of flying safety these days. The FAA and airlines work together to coordinate the flights so they can be resumed as quickly and safely as possible.
In a tech era where technology governs nearly everything in aviation, one breakdown can bring everything to a halt. On the bright side, however, they don’t last long and safety always comes at top priority. So the next time you see a brief delay, peek behind: it’s not chaos—it is thorough planning in progress.
