Another new pilot here - I've managed one Vatsim take off from a relatively busy EGKK and flew unicom from there to EGTE - it's crazy but I was a bag of nerves throughout the process on the ground and this wasn't helped by having two airliners behind my TBM930 waiting to take off while I was lining up. I couldn't activate the AP in the flightdeck as I had the screen restored down so I could use SimToolkit and vPilot, instead of just pressing Z I got myself flustered making for one very ugly climb - although I still managed to maintain my SID routing
It was still an unbelievably rewarding
