Humpix 2 Posted July 13, 2018 Share Posted July 13, 2018 Hi, I did my first flight, starting at LOWI, and I discovered a strange behavior. Starting at RNW08, BRENO2J SID (OEJ -> steep right turn -> INN -> steep left turn -> BRENO) https://charts.vacc-austria.org/LOWI/LOWI_Departure_SID RWY 08_020318.pdf Until the waypoint OEJ there is a speed restriction (165kn). After that there is only the altitude restriction 250kn until 10000ft and a very steep turn to the right. AT OEJ I was already at 10000ft (ok so far) and the plane accelerated extremely inside the turn to the VOR "INN". So it overshoots the turn (I think normal so far too). But. the next turn after INN to BRENO he doesn't get any more and the bus just flies straight on in the wrong direction, instead turning left after INN. I just flew over the waypoint INN, so I think the FMC should have registered that point and sould try to get back to the next waypoint BRENO... Either way, I got there extremely quickly to INN and I shoot the point not at the perfect path, but a little from the left side. So is this an normal behavior or an error?

Emi 5162 Posted July 13, 2018 Share Posted July 13, 2018 Hi Mathias, what happens if you enter a direct to the next successive flight plan waypoint? Does this bring you back into NAV mode and does the Airbus follow the new route then or does it simply continue to fly straight ahead?

BBoyJD10 12 Posted July 13, 2018 Share Posted July 13, 2018 I also have this it just flys ahead ... Link to comment https://forum.aerosoft.com/index.php?/topic/137256-lnav-does-not-follow-the-magenta-line-in-some-cases/#findComment-888795 Share on other sites More sharing options...
Emi 5162 Posted July 13, 2018 Share Posted July 13, 2018 And you are sure you entered ALL information correctly into the FMGS? We have seen lots of cases now where users forgot to enter some information and this in return prevented the Airbus from doing the required NAV calculations.

Humpix 2 Posted July 13, 2018 Author Share Posted July 13, 2018 Yes, a "direct to" work and the plane follows the route after that. All data and route are correct in the FMS. No discos, and of cource all other pages are set.

Emi 5162 Posted July 13, 2018 Share Posted July 13, 2018 Could you check this thread out and respond in there accordingly?

Humpix 2 Posted July 26, 2018 Author Share Posted July 26, 2018 Sorry for the delay - both pages INIT A and B where filled. I give it an other try tonight and re- + doublecheck all settings, payloads, ... BTW, it works well with manual speed at this section, so it does not overshoot the course. So no big deal at the moment. Im just not sure what the real plane would do. But for my understanding, it should try to get back on course instead of flying along? (I could be wrong, the real AP is a nasty thing) BR and thx!
