brtkstn 14 Posted April 16, 2015 Share Posted April 16, 2015 Hi guys, I have some problems with airbus (SP3) and LNAV mode. I made a short flight between EPWA-EPKK. STAR KUKAM1G has three 90 degrees turns at KK504, KK503 and KK502, as you can see in attachment. I was in DES, SPEED mode and the first turn was pretty good at speed 220kt (just a small overshoot), the second one was very poor, I didn’t saw third one, because the plane tried to follow some strange circles, that were drawn on ND and finally flew in unknown direction. I was angry and switched off simulator. PS. And there was no discontinuity. Prepar3d, Aerosoft Airbus A319 IAE, FSUIPC Active Sky Next (maybe here is something to do) Frame rate: above 30 FPS all the time Greetings, Bartek Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted April 16, 2015 Deputy Sheriffs Share Posted April 16, 2015 No need to get angry This can happen sometimes. Just go into HDG mode and fly it yourself or DIR TO the next WP if auto sequencing does not get you anywhere. Could be the programming or the wind, or both. Hard to say but you can always fix it inflight yourself, that is why a pilot is still on board. Link to comment Share on other sites More sharing options...
brtkstn 14 Posted April 16, 2015 Author Share Posted April 16, 2015 Thank you Frank for fast answer. Today I'll try the lower speed in these turns (200-190kts). On the chart IAS 220kts is max value. Maybe here is the clue. Greetings, Bartek Link to comment Share on other sites More sharing options...
brtkstn 14 Posted April 17, 2015 Author Share Posted April 17, 2015 Hello again, the speed has nothing to do in this case, strange circles are still drawn on ND. DIR TO function (to the next valid waypoint) makes a lot of more curves. HDG mode in simulation of RNAV STAR is not the best solution, in my opinion. Don't get me wrong, I'm not "a child of magenta", just want to have a good working NAV mode BTW I don't remember that I had problems with that in previous version (1.21 + all hot fixes).

Aerosoft Aerosoft Team [Inactive Account] 51558 Posted April 17, 2015 Aerosoft Share Posted April 17, 2015 Strange shapes on the ND are nothing new. Not to our bus and not the real aircraft. It's a fact of life for bus drivers and they simply fly the procedure. I am not behind my own system but I posted dozens of images from the real airbus showing the wildest patterns that even an aerobatic aircraft would not be able to fly.

brtkstn 14 Posted April 21, 2015 Author Share Posted April 21, 2015 Mathijs, when i bought the product i have read the description of it and was hoping, that LNAV is 100% working: Fully custom autopilot systems, with full Cat III auto land, V/S, Managed CLB/DES, OP CLB/DES, heading and NAV modes. VNAV and LNAV included. FPA/TRK included. Steep Approach possible on A318 It's hard to belive, that real airbus can't execute the simple STAR procedure in LNAV between few waypoints, but i'm not a real pilot and i was never in cockpit. My question is: are you treating it's like a bug or like a normal situation in life? I like this product, but there are some glitches, that are spoiling the full fun.

Deputy Sheriffs The Dude 6537 Posted April 21, 2015 Deputy Sheriffs Share Posted April 21, 2015 Which STAR does not work for you? Link to comment Share on other sites More sharing options...
brtkstn 14 Posted April 21, 2015 Author Share Posted April 21, 2015 Frank, as shown in first in first post, for example - EPKK, KUKAM1G.

brtkstn 14 Posted April 25, 2015 Author Share Posted April 25, 2015 I have recorded a movie with my problem, which is shown at 22:00: https://youtu.be/plt7wfLj_4s?t=22m. To see other phases of flight you have to watch a whole film. Greetings, Bartek Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted April 25, 2015 Deputy Sheriffs Share Posted April 25, 2015 Thanks Bartek, going to watch it tonight. Btw, did you ever try it with the approach phase already activated? Link to comment Share on other sites More sharing options...
brtkstn 14 Posted April 25, 2015 Author Share Posted April 25, 2015 Frank, nope, never. I'll try it also tonight. Thanks for the tip. Link to comment Share on other sites More sharing options...
Deputy Sheriffs The Dude 6537 Posted April 25, 2015 Deputy Sheriffs Share Posted April 25, 2015 Must not do anything but could. The FMGC calculates the FPLN with slower speeds when the approach phase is activated. Link to comment Share on other sites More sharing options...
brtkstn 14 Posted April 26, 2015 Author Share Posted April 26, 2015 Hello, activation of approach phase does nothing with my problem. Maybe you have any suggestions, maybe i'm doing something wrong? Greetings, Bartek. Link to comment Share on other sites More sharing options...
brtkstn 14 Posted July 1, 2015 Author Share Posted July 1, 2015 Hi guys, did you changed something between HF d - e about this problem? When I was using HF d and e, I had better results in LNAV. I also noticed, that in my problem is better to use NavDataPro than Navigraph. Now I'm using HF f with NavDataPro and I've meet another problem like in first post but in other place.

Deputy Sheriffs Tom A320 4915 Posted July 1, 2015 Deputy Sheriffs Share Posted July 1, 2015 Please state the exact flight plan so that it is possible to try to reproduce your problem. Link to comment Share on other sites More sharing options...
brtkstn 14 Posted July 1, 2015 Author Share Posted July 1, 2015 Hi Tom, my flight plan was EPKK-EPGD - POBOK1J POBOK DCT KOTEK N133 IRLUN. I fly whole SID, and the problem occurs between POBOK and KOTEK waypoints, same as in first post. I think, that with HF d or e (don't remember exactly) the Bus was flying with bigger curve over KOTEK, but the plane found the proper way. Now with HF f, line between POBOK and KOTEK destroys in the middle and the plane flies in unknown direction. Bartek Link to comment Share on other sites More sharing options...

Deputy Sheriffs Tom A320 4915 Posted July 2, 2015 Deputy Sheriffs Share Posted July 2, 2015 Hello Bartek, I finally was able to test your route, with the A318 1.30f. At first everything was fine... But after overflying POBOK the line drawing messed up and the bus "lost itself" But a simple DIR TO NEGUV fixed it easily In RL things like that also happen some times and that's why there are still pilots I can't tell if it was newly introduced with hotfix f, I doubt that there will be much time invested now to fix it. Especially as there is a simple workaround (which is also used in RL). Link to comment Share on other sites More sharing options...
kaktus018 7 Posted July 3, 2015 Share Posted July 3, 2015 Yep, pull the heading knob and set a heading that matches your flight plan. Once back on track use DIR TO. I actually find it quite interesting that this happens in the RL bus (as this isn't such a big deal, at least in stationary flight). Link to comment Share on other sites More sharing options...
Deputy Sheriffs Tom A320 4915 Posted July 3, 2015 Deputy Sheriffs Share Posted July 3, 2015 A nice RL example: http://forum.aerosoft.com/index.php?/topic/58780-airbus-x-extended-preview-topic-closed-product-released/page-27?p=420097#entry420097 Link to comment Share on other sites More sharing options...
brtkstn 14 Posted July 3, 2015 Author Share Posted July 3, 2015 Thank you Tom for that test. Paradoxically I was flying yesterday that route and it was... all good . One thing I noticed, I was in OP CLB mode. Has it something to do in that case? So I'm waiting for new auto flight system. Thank you once again.

Deputy Sheriffs Tom A320 4915 Posted July 3, 2015 Deputy Sheriffs Share Posted July 3, 2015 Hello Bartek, I just repeated the flight on OP CLB but run unlike you into the same problem again... Tom. Link to comment Share on other sites More sharing options...
brtkstn 14 Posted July 4, 2015 Author Share Posted July 4, 2015 Tom, thank you very much, that you have looked this problem. I'm leaving this thread until next service pack will be relased. Bartek Link to comment Share on other sites More sharing options...
MarkrB 3 Posted July 6, 2015 Share Posted July 6, 2015 Just out of curiosity I wonder if this happens with both sets of AIRAC data sets. Are you guys using NavDatPro or Navigraph? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
