Good evening.

Take Farnborough. The default setting is planes landing at runway 25. Below is the arport information.

Farnborough (EGLF)

You got all this stuff, but don't know what to do with it huh?

Alright then.

First off, enter your ILS frequency (111.55) into your NAV 1 area on your radio stack and turn it on.

Now after that, you should here annoying little beepings every so often. If you do then it's working.  Now click the approach button. When you want to finally get lined up, turn on Auto Pilot, and the plane should turn itself to the runway frequency. You still must use the flaps and speed and ect.

I'm not sure if you can use ILS approach on a cessna or not. Never tried it.

Sometimes, this doesn't work. I have big Heavies lined up, then once I turn on the ILS, they freak out, and take a hard right to the middle of nowhere. But this should work.

Okay, done that.

Indeed, I had my Pink Floyd CD on at the time, so I pressed Q.  ;D

Now click the approach button. When you want to finally get lined up, turn on Auto Pilot, and the plane should turn itself to the runway frequency. You still must use the flaps and speed and ect.

Ah. What plane do you recommend using then?

I've just been doing that before I saw this post, and that's what happened, except mine went to the left.

I'll let you know how it goes.
Thanks.

Very impressive indeed. That helped a lot.

Okay, now how do I get the autopilot to bring the plane down the glideslope?

Just like it says:

Once you have the right frequency and you hit Approach and AP the plane does it by itself. :)

Just to confirm, the Cessnas (in fact, almost all the FS2002 aircraft) are capable of ILS approaches. Simply approach the ILS the way you normally would, and whenever you see the needles start to move, you should be able to hit the APR button on the radios and it will take you right down, assuming the runway has a glideslope installed.

Farnborough must only do the localizer then and no glideslope then.

It appears that way. If you don't have access to the ILS frequency, or an approach plate. You can "test" different frequencies, by visually ligning the A/C up on short final, pausing the sim, and then cycling through all of the possible frequencies...... 109.1,109.3,109.5....etc., etc., etc..... The most "standard " frequencies will be 108-111 and odd tenths.......  .1,.3,.5,.7. If you want to try it again go up the road to Heathrow Rwy 9L/110.3/093degree course. Also, when I used to instruct, I would have my students fly the approach visually, and then, on instruments. In this case, this allows you to bring ALL of the elements together;Course-frequency-altitude- tuning&identifying the signal;coupling the Autopilot for the approach.
The standard FS Cessna Autopilot WILL do it, by the way. 8)

I also find it useful to use the EFIS which allows you to see the glide path.  Plus, if you want to, you can drop the AP and fly the HUD. 8)

"What we have here is a failure to communicate!"
I was able to pull the actual Jepp approach plate from work , and this isan ILS approach, not just a Localizer. The frequency is 111.55, and the course is 245.  ??? ??? ???
The problem is, ILS runway 6. It's inbound course is 065degrees, and the frequecy is also 111.55!
This is something Iv'e never seen in the States before. Which as we all know, is the only country M$ likes to admit to the existence of.
Until now, every runway I have seen with upposing ILS approaches, had two different frequencies. If a runway has an ILS approach only in one direction, the "backside" can be used for a Localizer approach only. That is, if you approach an ILS runway from the wrong direction, you will only recieve course guidance, and no glideslope indication.
Consequently, the defaults for FS should duplicate this phenomenon. If you  
have what is affectively the same ILS in both directions, with the exception of the course, I suppose the result would be the program simulating both directions as a "back-course"!  :-/   That's my theory, and I'm sticking to it ! ???

Ok, let me do this a little simpler, first off I suggest a simple airport, try McKinney Municipal (KTKI) in McKinney Texas. LONG runway, you can practice with any aircraft there. Tune the runway 17 ILS frequency in NAV1 while at the end of runway 17 preparing for take off (17 is the default runway). The horizontal bar should move to the top of the guage or the attitude indicator, depending on the aircraft you use.
Take off, fly the pattern, request a Touch and Go landing. Fly the plane south of the airport, use the VASI or PAPI lights (those are the red and white lights to the left of the runway) to line up, when you have two red and two white lights, turn and line up with the runway, keep there two red and two white lights and you are perfectly on a visual glidescope. The ILS beams on your gauge will show a perfect approach if you folllow a visual.
Now, the autopilots in the airliners and commuters are MUCHO BETTER at following an ILS then a Cessna is. However, the whole thing is screwed, and you will need to pretty much put it on the ILS yourself before the A/P wil take over and fly it. Turning it on at a random altitude and heading will usually result in hell going loose, since the A/P will oscilate the plane all over trying to capture the course (I decided to see if this was the truth, flew it in a real Cessna 172 at KTKI, which is my home airport. by the way, ILS isnt standard in a 172, a damn A/P isnt standard lol. The autopilot preformed a smooth turn to 176 (runway heading) descded, captured the glidescope, and flew the approach, no problemo). Notice, you should NEVER let the plane fly the full approach to the ground, it is bad for you, and it is NEVER done in reality. If you cannot see the runway by decision height, go around, DO NOT FLY THE APPROACH. Heavies sometimes use the APPR feature even in good weather, since they are hard to move around anyways. If you use the approach feature in Flight Simulator ALL the way to the runway to the ground, you will hit and you WILL hit very hard. (for some reason, M$ took out the feature which was in 95 that caused the airplanes to flare at the last second, gave a VERY smooth landing).
So, simply, tune the ILS, get the bars in the center of the gauge, and fly a normal approach, or get the bars in the center, let the A/P fly the approach to decision height, and you land it.
Once again, DO NOT let the A/P fly the approach all the way to the ground, it will hit still desceding in an approach, and will break the landing gear off most realistic planes and leave you surrounded with fire trucks. Good luck, have fun, and I hope this helped! ;)
