Frafty 6 Posted December 27, 2018 Share Posted December 27, 2018 Alrighty, so got an update for you with video. Here's the precursor information: A320 IAE DCA-MSP: HORTO3 BUFFR J518 DJB J34 VIO DCT KAMMA KKILR3 Right before the video starts: I'm right at TOD point. I'm coming from FL360, where the first restriction is 14,000 ft at CMAAC. Immediately, upon pushing the button to descend, the plane dives and chases the magenta all the way down. I wait to see if it's going to correct itself, but it doesn't, so I have to deploy speedbrakes. Once I do and get it back on profile, it handles beautifully. It's like it can't calculate the initial decent to meet the very first restriction to where, out of the gate, it's already behind. I've done two flights now, and I decided to record this one to show you. I hope it helps!

Frafty 6 Posted December 29, 2018 Author Share Posted December 29, 2018 Just to provide more context, maybe in the mindset of process of elimination. Just flew an approach into Missoula, MT (KMSO), and the aircraft had an absolutely flawless decent management round. No speedbrakes used at all. The one thing different here vs the other flights where I encountered issues was there was no STAR. I flew straight in via the RNAV RWY 29 approach. I'm about to do a quick turn to head back to Denver, so I'll let you know if I experience anything different and maybe rule it down to STARS causing issues with the decent management system in the A320.

Frafty 6 Posted December 29, 2018 Author Share Posted December 29, 2018 So after just landing in Denver, I'm confident STARS are where your buses struggle. Flying into KDEN from KMSO on the MOLTN3 arrival from the OPEE transition, the bus immediately from initiating decent falls behind the decent profile. Additionally, you see later on approach that the plane nose dives to get to the next altitude restriction. The video didn't save that I made, but after focusing on STARs in the bus, I can confirm that's where the problem seems to lie. Link to comment Share on other sites More sharing options...

Descent is initiated right after the video begins. Also, never mind the approach. Link to comment Share on other sites More sharing options...
raf120 1 Posted December 29, 2018 Share Posted December 29, 2018 I have same situation but on start descend to CYVR. Airbus a319 CFM Route;: PANC - CYFR, NOEND DCT MDO J605 BKA J195 ANN J502 YZT with star WHSLR5 (rwy08L) CI: 30 P3Dv4.4 Link to comment Share on other sites More sharing options...
Frafty 6 Posted January 1, 2019 Author Share Posted January 1, 2019 Doing another flight, same thing descending into KSAN via this route: BAYLR4 TEHRU DCT PLNDL Q86 TTRUE LUCKI1. Same result. TOD initiated 2-3 miles before the TOD arrow, and magenta dot plummets to the bottom of the PFD, causing the A/P to chase all the way down to catch up to the descent profile. Any word on this from the devs? I know it's the holidays, but genuinely curious if any headway has been made on at least conducting a test flight to see if you yield the same results?

Deputy Sheriffs mopperle 4161 Posted January 8, 2019 Deputy Sheriffs Share Posted January 8, 2019 The problem is to recreate such an issue. I just made a flight from EDDM to EDDH, with real (heavy) weather with rev. 1.2.2.1 of the Airbus and had zero problems. No CTD, no managed speed issue, no VNAV issue... Currently we simply can only collect infornmation to find any hint. why some users experience such problems. Link to comment Share on other sites More sharing options...
Frafty 6 Posted January 9, 2019 Author Share Posted January 9, 2019 Maybe you can try performing the same flight I did in the initial post? KDCA-KMSP with that route? I'm convinced STARS are causing the issue. Link to comment Share on other sites More sharing options...
Frafty 6 Posted January 9, 2019 Author Share Posted January 9, 2019 I mean, after all, we're asked to provide that information for a reason, no? Link to comment Share on other sites More sharing options...
boss128 1 Posted January 11, 2019 Share Posted January 11, 2019 Hi Frafty, the problem with the rapidly droping magenta ball on enganging a managed descent pested many of us since the release. There must be a number of threads from Sept/Oct (with a lot of people reporting the same problem) and if my memory serves me correctly Aerosoft stated finally that they are able to recreate it on a machine now (in October 2018). Unfortunately only the aggressive climb was fixed and the descent optimized but this particular problem has never been adressed/fixed. I still have it and had it with all versions thats why I simply don't use the bus. It's a shame but it is what it is - maybe in future this will also be adressed. br Link to comment Share on other sites More sharing options...
Frafty 6 Posted January 14, 2019 Author Share Posted January 14, 2019 Poking this thread again. The test that was done wasn't even done using the same parameters I provided above. Link to comment Share on other sites More sharing options...
Frafty 6 Posted January 25, 2019 Author Share Posted January 25, 2019 You can close this thread. Since it clearly won't even be properly investigated, I've decided not to waste my time with this product and its incredible amount of difficiences.

Deputy Sheriffs Secondator 643 Posted January 25, 2019 Deputy Sheriffs Share Posted January 25, 2019 Hello Frafty, We have been investigating this issue recently and have noticed that there is some anomalies with the VNAV that we can recreate. However I cannot give you an estimate for the fix right now, but we are looking into it. We constantly monitor these forums and even though you might not always see a reply, we are taking a look into every issue that we see and try to see if there is something into it. I hope you also understand that it can take time for us to recreate these issues and they might not happen always even if we use same parameters etc. Link to comment Share on other sites More sharing options...
