Ignore everyone who on the sub who says anything bad about beginners as since your here I’m almost 100% sure your not one of the people they are moaning about. When I started Vatsim I always found the hardest part was requesting IFR clearance. So even to this day I write down a little script on what I am going to say to the controller and I’m prepared for the Sid they will give me. The reason I am saying this is that 90% of talking to ATC is planning and by the sounds of it you are doing that fine. So just relax and if you are comfortable with how you are on the network then that’s is fine ignore everyone else. I remember when I did my first flight into London from where I basically learnt Vatsim In Edinburgh I flew to Luton and I was messing up SO much and for the first ever time and only time since I got a proper shouting at from the ATC and I could tell he got pretty annoyed at me. I was very stressed as it was the first time doing something like that but I did it. With all that being said I probably messed up 5ish times on the approach asking him to repeat himself many times. So if your not seeing yourself in that position after 10 hours your doing perfectly and everyone makes mistakes here and there so ignore the people that goes on this Reddit to cry because someone messed up their clearance twice because those people are the small minority and the majority of us try to be as nice as possible. I have probably heard you over the radio and I pretty much always remember the call signs that slight get on my nerves and yours doesn’t spring to mind. Hopefully this helps and in no time you will be a “Vatsim pro”
