I've recently done a flight into EBCI with the KOK7A arrival RNP24 Approach with the GUGNO transition. As you can see on the picture below the FMC is bugging into top of decent during the arrival/approach transition. I've tried this with other aircraft with no issues so it seems to be a problem with this system.

Any advice would be super

*UPDATE*

I think I've figured out that the GUGNO and VAMKA waypoints are being picked up from a duplicate waypoint on the other side of the planet 😅

These can't be amended on the approach as it seems they're defaulted to the duplicates. What a nightmare!

Hi,

Are you using default navdata or Navigraph?

Thanks!

Hi Kyle,

I'm using navigraph 🙂

Thanks

I’m wondering if there may be a mismatch somewhere, as the aircraft uses the default sim navdata.

I’ll do some testing on my end as well. Thanks for bringing this to my attention!
