As KK says, the mouse control isn't easy to keep the a/c on track
also you have a chart / list of ATC's not in order / and instructions
I found it better to write down the calls you think you will have to make
as G-ABCD doesn't come naturally
also, you will enter SVFR, and have an engine problem, you will leave the
coast - reporting point and eta etc needed, then when over the water, you
will see a problem below, - forwarding a mayday, then when you think its
nearly over, the final destination will close on you, leaving you to re route
and make calls to tell the new ATC , the normal stuff + re route.
Good Luck
take your time, and practice as long as he will allow
