It's alway a good idea to have the approach plates(charts) for the airport you are flying to, there you will find the intercept altitude for the ILS/VOR DME and decent profile.
As well as the STAR(standard terminal arrival) or arrival route.
Althoug FS9 ATC does not use this.
You all the info you need about the airport you are flying into.
Charts can be found in the Pilots Lounge in the Propilot section or be bought from Navigraph(

And you should try to fly online with real procedures. Gives flying a new dimension

Murray for online training.
Good luck with your further flights and happy landings:)
