Currently you are assigned a callsign, and a tailsing. And a starting location. --tipically around your home base.
Then you will plan a flight (using airlines from the airport of departure) and complete the flight on the best of your skills. Then Submit the flight for ranking the hours. You can proceed, by departing the last arrival airport. And a new flight plan.
Rules:
1. Always taxi. From gate/apron/tarmac to departing runway. And, on arrival, from runway to a gate/tarmac/apron. JAFVA flights are only valid if taxiing is evident on your tracking log
2. Always verify you are tracked. The tracking file you submit is your only evidence that the flight was completely properly. If you aren't being tracked, you arent getting a valid flight.
3. Never modify simulation rate. That would cause your flight to be invalid.
4. Always use the proper Callsign, for a JAFVA flight
5. When in doubt, come to this thread for help
6. Share your adventure with us, on this thread as well
