Hi Umberto,
Below is the Couatl error report when I was 11nm out of Rwy 20 at Lisbon in FS Labs Concorde in P3D v5.3HF2.
couatl v5.0 (build 6224)

The message is odd because I departed from Gate 44 at EGCC Manchester and didn't select a parking position at LPPT whilst airborne.
I opted to restart Couatl and all was well thereafter. I selected the parking position but didn't opt for the FolllowMe as I had taxi guidance from Aivlasoft EFB.
