Problem with one line of data? Better shutdown the airspace.

Amazing this hadn’t happened before with a strategy like that.

Also, duplicate waypoints are allowed, just not in the same region. But also exit points don’t have to be explicitly indicated and the system will just look for the nearest waypoint in another region.

Sounds like the whole thing was a needlessly hacky messy standard. I’ve dealt with quite a few of them, but to tolerate it in air traffic control? Good grief…
