I use MSFS 2020. The settings in the scenery library menu are:
1 Microsoft flight Simulator 2020
Navigraph - Airac cycle 2212: Do not use Navigraph database
Airspace libraries - Simulator
I updated to the latest version 2.8.5 and cannot see the TACAN frequencies. All the TACAN appear as VOR and show VOR frequencies. Is there a way of changing it in settings? Thank you.
