Hi guys. I'm not really a pro at starting new topics since I always find a solution to my problems but this time I cannot figure it out so let me explain what's happening with my Synaptic A220 :

When attempting an LPV or RNP approach (basically RNAV approaches), LPV arms correctly, and APPR FMS1 shows as required when pressing APP on the autopilot. When approaching IF, VGP starts showing on the right corner as needed. Then it starts capturing VGP, again as it should. But then, when reaching next FIX, still on the app PATH, it immidiatelly switches to FPA, with a FD mode change, and it is absolutly IMPOSSIBLE to come back to the VGP. It leads then to a manual overtaking of the aircraft to avoid being late on the Glide path, and it is super annoying, because it never happened with version 1.0.7 and older, but since the update 1.08, it is happening everytime.

Does anyone has encounter the same problem ? Or am I missing something here ?

Thanks in advance guys for all your (future) answears

Hi,

Is this happening on every LPV/RNP approach you’re flying, or has it only occurred at one particular airport?

Thanks!

Hi !

On basis of today's flights that I made, which was a 4 leg rotation from LDZA to LDDU then LGAV back LDDU and LDZA, it did happened every time yes.

For references, I did the RNP Y Rwy 03R at LGAV, once the RNP Rwy 11 at LDDU and the RNP Rwy 29 (AR), then RNP rwy 04 at LDZA.

Thanks a lot !

I'll note this and pass it along to Synaptic for further evaluation. For reference are you using Navigraph or default sim data for your AIRAC?

Thanks!

Navigraph, the latest.

Thanks a lot for your help.

Hi again, just got an answear on Discord, problem is known for LPV approaches and it is already fixed and will be published on 1.0.9. If someone has the problem, here is then the answear. LNAV/VNAV (RNP) does work, but should be selected on the approach mode if wanted to be followed of course by the aircraft.

Thank youuu.

Awesome news, thanks so much for the clarification!
