I am currently flying the CJ4 and I follow real world flights operated by a CJ4 operator based in Hamburg. I check on flightradar and started to have a list where I enter all the flights to follow.
Once I can get the first Airliner in the Sim (the CRJ) I I’ll pick a real CRJ, check it’s recent flights on flightradar, make a list including the correct Callsign, departure time, departure gate/ position and FL.
I really like to have this real world touch, that’s enough “mission” for me.
