You have succeded in an ILS landing when the wheels on the aeroplane thingy contact the runway thingy and you stop before reaching the end.
The easy was to do it is to set your altitude to 2000ft and use the GPS system to navigate into the green triangle that represents the ILS system. Have the NAV1 radio switched to the frequency of the ILS of the runway that you are landing on and as you approach the green traingle watch what the needles do. Practice on the cessna it is easier.
You will notice that the two needles divert away from their centre lines. The horizontal needle is the glideslope and tells you what altitude you should be at. The closer you get to the runway the lower you should be. The verticle needle is the centre line of the runway. The trick is to fly towards the needles.
Most glideslopes are set up so that you are descending at 3 degrees which works out at approx 500 feet per minute at 90 knots. Trim the aircraft for 90kts in straight and level flight, as you see the ILS needle start to deflect downwards try to get the VSI to 500FPM whilst maintaining 90kts (flaps can help). At the same time watch the vertical needle and fly towards it when it deviates from center, keep your inputs small and smooth.
Practice makes perfect, use a light aircraft and fly circuits of an ILS equiped airfield with the ATC off and AI traffic at 0% in broad daylight with cleared weather. Use the visual clues to guide your interpretation of the ILS needles. When you can keep the aircraft on the ILS in the above conditions try reducing the visability a little at a time, when you can do it in zero visability in realistic weather conditions at night with a four year old on your lap pushing random buttons for you and shouting "crash it daddy" you will be a happy man.
Good luck mate.
