UK air traffic control meltdown
UK air traffic control meltdown
There is a discussion on Hacker News, but feel free to comment here as well.
Sometimes a tl;dr really helps.
If I understand the article:
-
a flight plan is a series of waypoints.
-
Waypoints are represented using identifiers that are known to not be globally unique.
-
an algorithm attempts to extract the portion of the flight in the UK airspace failed due to one of the non-unique waypoints in a flight plan
-
the failure caused the primary system to halt
-
the backup system takes over, processes the same flight plan and fails the same way, halting as well
-
UK air traffic control can no longer accept/process flight plans, preventing flights from happening
-
it took a while to resolve the system error, and longer to resolve the impacted people
Thank you.
