So I discovered a trick if your using a custom livery from flightsim.to . My understanding is to get the passengers seated and not showing up in pink color needs to be an airline ICAO which couatl
script needs to identify.
So a work around is if you have a custom livery.. Example is I have a custom Ansett Fenixa320 Livery downloaded from flightsim.to.
So I did the following....
1- Open Community folder> Find, select custom livery folder> Sim Objects> Airplanes> FNX320 > select the aircraft.cfg & open with notepad > Scroll down and locate the Airline ICAO code.
And change the ICAO code to one the couatl scirpt will identify.
For myself with Ansett, I changed the airline ICAO from "AAA" to Jetstar which is "JST" As the script will or should have JST in the data base, which it did.
