1.04 - Simbrief FPLN Upling Pending.

Featured Replies

In version 1.04 the framerate seems to got somewhat better on Xbox. However, now there is another problem: Simbrief Flightplan uplink is not working. In the Tablet importing the plan as well as W&B works, but in the FMS it gets stuck at pending. After two weeks, still not usable ... come on guys!!!

And before you ask: Yes, I did deinstall and reinstall the plane already.

Hi,

Sorry to hear you’re having issues with v1.0.4.

I just wanted to confirm that you’re on the SEC flight plan page when attempting to import your flight plan. The flight plan will not import if you’re on the ACT flight plan page.

In the meantime, if you’re able to, I’d suggest joining the Synaptic Discord, where they may be able to provide further assistance and troubleshooting.

Thanks!

Yes, obviously. I did my research before trying to fly the plane. I´m on the SEC flight plan. it is stuck on pending. On version 1.02 this did not happen, but of course the performance here was so bad that it did not matter. This release is an absolute disaster two weeks later, not a single flight was possible ...

Hi Kyle,

thanks, I will have a look in the Discord. I figured out if using the old navigraph data base the uplink works. Maybe this is a issue mit the updated default database together with simbrief. But at least this works for now. Let´s see how performance will be ..

Hi,

You are absolutely correct. There is currently an ongoing issue with the default MSFS NAVDATA, and I apologize for not catching this earlier.

Hopefully, you’ll see a noticeable performance improvement with v1.0.4!

Thanks again for bringing this to our attention.

Sorry to bother again. Regarding the navigraph data base, I can not update it on Xbox. I watched the tutorial (https://forum.inibuilds.com/topic/37236-how-to-update-navdata/) but as it seems there should be a option to authenticate the FMS with the navigraph account. And this option does not show up in my case. Hence, there is no new data base to download and then upload in the FMS.
At the moment I am stuck with the old navigraph data base which is not ideal. Is this a know bug? Or am I doing something wrong?

Hi,

You need to authenticate Navigraph in the settings tab of the tablet.

Once that is done, follow the steps indicated on that tutorial, but at the top, select LOAD NEW DATABASES.

Hi Kyle,

I am authenticated in the EFB. Still, in the "Load new database" nothing is showing up to select. I tried starting the flight new, starting the sim new and after updating the plane de- and reinstalled it altogether (just in case you would bring this up as possible solutions).

And an update on the performance. It is still very poor und not much enjoyable. However, it makes progresses. I am at least able to do some flights, albeit it stuttering and laggy. If they keep the pace I can imagine that it will be acceptable in some time. This should still not be necessary. A product has to work on release, not weeks later. But at least they are working actively on fixing the performance issues.

EDIT: Yes, I know. Synaptics has a discord. But for one some users there are super toxic (I read some posts, not the Synaptics team of course), and on the other hand the channel wants me to verify a phone number and I am not going to share my phone number with discord.
