RANT is never worth £90 !!! - Unless your loaded.
Buy FS2002 Std Edition for £25 instead.
Choose a plane, take off (you can't do that in RANT), turn on the AP and set Alt hold, and Air Speed hold and then do all the things you do in RANT, but with more realism.
I found it far more useful to fly the King Air out of Oxford via the airways to Bristol, Birmingham, or EMA etc and do some holds and approaches, with FS2002 than RANT.
BTW I have a FS2002 patch that puts the DME into Oxford that was left out, if anyone wants it.
