I don't see it said anywhere that the two same-named waypoints were consecutive, with no other points between them. Just that they were "approximately 4000 nautical miles apart". Or that being consecutive duplicates rather than just duplicates was the cause.
Since they don't name the waypoints, it is very vague.
- zimpenfish 3y agoAs best I understand page 9 of [0], it sounds like the search for UK entry and exit points led to the A and B being found with no specified entry/exit/waypoints between them, and therefore "the software could not extract a valid UK portion of flight plan between these two points".

- SideburnsOfDoom 3y ago> the A and B being found with no specified entry/exit/waypoints between them No waypoints that enter UK airspace between them, since "In this specific event, both of the waypoints were located outside of the UK". (1) So there could be any number from zero up, of international waters waypoints between them? 1) https://publicapps.caa.co.uk/docs/33/NERL%20Major%20Incident%20Investigation%20Preliminary%20Report.pdf https://publicapps.caa.co.uk/docs/33/NERL%20Major%20Incident...

For me, it read like "there was no route between Aa and Ab because there were no waypoints available between them". But yeah, without a more detailed breakdown, information, and/or a better understanding of the precise format of the files and procedures, it is going to be a bit of assumption and guesswork.
