#1 rule in instrument flight:
Never get airborne to fly any procedures unless you have practiced them in a sim on the ground beforehand.
Otherwise you are wasting your time and money. If you don't know what to do in your armchair at home, learning it in the air is pointless.
Get a copy of FS2004 or FSX, a cheap (£10) joystick - no need for the fancy yoke - and practice the procedures.
