zxmpitoday 26c tomorrow 26c friday 26c... i can only hope the cornetto supply holds out01:46
knightwiseIt was toasty indeed yesterday06:33
penguin42https://www.caa.co.uk/newsroom/news/regulator-to-launch-independent-review-of-nats-technical-failure/   has the link to the report into the air traffic failure - it's actually quite interesting15:18
davefAhh good old NATS, once charged the company I worked for at the time £10,000 for AFTN access, which turned out to be a super low end HP system and a crusty X.25 modem.19:21
penguin42heck, how long ago was that19:50
davefA while now, about 15yrs ago21:06
penguin42heck, x.25 well into this century21:07
davefWe also use SITA TEXT which used to carry the AFTN traffic and fed direct into the flight planning servers, they turned around and said “welp, we’re not doing that anymore lol” .. I then ended up working for SITA when I moved to Canada 😂21:08
davefYeah, I started working for the enemy lol21:09
penguin42but could you cope with a flight plan containing two waypoints with the same name?22:39
davefI would hope so. It's pretty much top shelf flight planning in the industry.23:05
davefIf you fly planes, you know about Jeppesen.23:06
penguin42apparently that was the bug, some corner case where the single flight plan passed through two waypoints with the same name but a few thousand km apart23:08
davefIt can and has happened.23:08
davefBut the software that Jepp developed was smart enough to know you want the waypoint enroute, not the other side of the planet.23:09
penguin42davef: So I think in this case the flight plan validly had both waypoints with the same name in it23:10
davefThe hope is somebody would catch that before the plane gets up in the air23:10
penguin42davef: No, I think they're saying it correctly had those two waypoints in it - it's just that freaked out the NATS code23:11
davefthen that's just bad NATS code23:11
davefremember when NATS launched? it was a hot mess.23:11
penguin42yeh, it actually seems like a 3rd party they were using23:11
