Buy RANT
P-S is right, RANT looks crap (a bit DOS like) and you can't use a joystick with it and scanning cannot be covered in it but as I said before half the IR is flying one hold perfectly with a wholly inadequate instrument, namely the ADF. All I used RANT for is flying holds and getting procedures sorted in my head.
For scanning I find FS2002 with a joystick wholly acceptable. Set the cloudbase at 200' put a decent wind in and away you go. Free approaches at any airport you like.
I got my money back on RANT at least 20 times over in terms of saved flights. Buy RANT Buy RANT buy RANT.
