Hello!! Its nice to see you actively seeking answers regarding your ghosting.
The tips provided are really good and Tyler even shared a youtube link which definitely got me through a portion of IF.
I spent a huge portion on the training server even though i reached a grade allowing access to the expert server. During those time, i was actually paranoid and feared getting a ghosting, i practiced really hard and made sure i know 100% of what i needed to know before entering expert.
So i spent alot of time learning ATC commands and getting feedback from IFATC members, joining session of TS ATCs and learning what i did right or wrong. When i was very sure i started my first flight in expert, it was really scary and i sat at my gate for a really long time going through my personal briefing so as not to screw up.
My first flight went really well and i was never ghosted from expert. I understand what its like to process so much information in such a short time so i opted to take very slow and deliberate steps to make sure i am so ready nothing could possibly go wrong.
I know this is kinda common sense but im writing this with genuine intention to help, if you feel there is even the slightest sense of being less than ready to enter expert, spend a little more time on TS and ask around ^^
All the best on your next expert experience, i hope you continue to improve well and see you in the skies of expert some time =)
