Just had a look for you....
Make sure that GPS/NAV switch is to NAV.
You have to be in a position where you will soon enter/meet the ILS. Switch APR Hold on and watch. As the vertical axis approaches - plane will follow, same for horizontal. I think they've gone so far as to put the decision point in so make sure AP is turned off at the inner marker otherwise you will crash. (Backcourse hold doesn't work though - turns you round and flies you away - a LONG way away)
Very interesting practice setting 8/8 to the deck and see how you go.
Even more fun - try a real one. This is how I started. One minute I was clocking up hours in the lounge room - the next paying out the bucks to learn to do it for real. And for anyone calling you a crap amateur don't listen as THEY all had to start somwhere too.
Good Luck!!
