ATC weirdness

No, the weather is fine, just set your weather to whatever you want. I’d go have a listen to VATSIM - get an account (free) set up VPilot (fairly easy), put a Cessna 152 on a maintenance pad in an active airport and just listen to the comms and watch the aircraft.

Then find somewhere quiet, where the ATC aren’t trying to handle 37 flights at once, sign up for a flight, mark yourself as ‘beginner’ and have a go. Do VFR first, it’s easier, you don’t have to worry about the plane so much.

Put it this way. You can’t make a bigger mess of it than I did first time out.

Most people on VATSIM/IVAO are nice and helpful, and they all know how nerve racking it is the first time.
