If you were wondering if you could change your display name in this discord server to match your airline name (e.g. VFL0789 Billy), here's what you need to do:
You can change it...
If the simulator crashes mid flight, or you lose your connection to the internet, or anything else that might cause you to not be able to file your flight automatically through ACARS, it's not the end of the world. You can still file a "manual" PIREP (short for "Pilot Report") - but you have to be mindful about how you do it if you have flown the leg of a tour:
Here's the important bit to remember - tour legs will only be marked as complete if you file a manual PIREP that is pre-filled from a dispatched flight. Just filling in the correct flight number into an empty PIREP isn't enough.
If you're not running FSUIPC in the background, ACARS will ask you to run it with administrator rights. Ignore it.
Just make sure FSUIPC is running and connected to the simulator in the background.
If ACARS complains again (perhaps about being at the wrong airport), just try starting the flight again - it will start, but sometimes takes a couple of tries to sort it's life out.
There are two reasons why ACARS might report you are not at the correct airfield (either to start, or end a flight):
I'm in contact with VABase about the airport database, because it's very annoying.
