Does anyone knows how to tune to the ILS for the aproach. When I fly IFR and I am instructed to mentain a certain heading and altitude until establish on the localizer .I never see any movement on my VOR1 indicator. Do I have to be tuned to a frequency before I intercept the glide slope, if so, how do I do this?

I have found this to be a pain sometimes as well. lately I've been practicing with the Cessna since it is easier to fly, and I'm rather busy trying to do what the tower is telling me to do. As far as i have figured out so far is to watch the VOR's horizontal line to make sure if I'm too high or too low. The verticle line still bugs me. In the interest of cheating I'll turn on my GPS with a 5 mile or 2.5 mile scan to make sure I'm lined up right. I compare that with the VOR verticle line. I will be lined up, but the verticle line is still to one side regardless of how much I twist the compass ring. But the horizontal line keeps me from nosing a building or overshooting the field.

I try the above in bad weather with 1/4 mile visibility so I can't see the runway until the very last minute. I think I'll stop doing that until I get better at it.

If I find the trick, I'll let you know. I am sure there are others here who know how to do this. They read your posts, but they don't offer any help.

On Flightsim.com, downloads, view all lists, fs2002, sounds, there seems to be some files which might apply to your quest. Can you get on to flightsim? I have an account there now. If I know what file you are looking for I'd be happy to grab it for you.

many of these files seem to be 'Sky Song Soundquest'. Maybe there's a website for them.

Hi,
If you have problem with ILS intercept, remember that you must have tuned to the frequency of the Localizer before intercept the glideslope.
At the same time you must intercept the glideslope from the correct distance and altitude: not over the glideslope (see approach map for the airport you intend to land to).

You can find some good tutorials here: http://www.fsfreeware.com/dcd/Tutorials/index.html

I found out that I have to be tuned to the ILS. Thank u guys so much. Now, are there any websites I can get airport information from? ILS frequencies etc.

Thanks

About charts try theese sites.
At NavDAta you should register but is free of charges; there you find also all databases for SB, FSNAV etc.

At NIMA, see at page bottom for Terminal Instrument Procedures, where all regions of the world are detailed.

Thanks Robetto

I will check the web site

to get the ils freq without having to go online. ckick on the map view, find the airport you want, click on the runway and all the airport info is supplied, ils freq, rwys, msl elevations etc.

I tried both the website and cherokeeflyboy's advice and SOME of the localizer frequencies does guide the aircraft (Boeing) to the runway, it does work fine for all other aircraft though.

Thanks guys

All the information you need for an ILS approach can be found within FS2k2 as Cherokeeflyboy stated. To restate, open up our map window by clicking on the compass resetta icon. Dont confuse this with our GPS window, which you open by using the F3 button.
Find the airport of intrest and click on it. You might need to zoom in to differentiate from other nearby objects. You will now notice an info chart. At the very bottom, if you scroll down, you will see runways for that airport and their respective info.

You will need:
1. Runway name (usually the longest one for that airport since FS2k2 uses the longest one at each airport. Also remember that each runway will have two sets of infor, one for each opposite direction.)
2. Distance of the runway.
3. Elevation - so you know what alt. is your floor. This is especially important if you're flying IMC (Instrument Meterological Condition) with low ceiling and vis. You also use this infor to base at what alt. to flair for you landing as well.
4. ILS frequency
5. The exact magnetic heading of the runway. Reason being the runway names are rounded off to the nearest tenth. This is what you set your VOR to if you what exact performance (well as much as expected for a MS product Wink

)

You can go through the trouble to find them on line, but some are different than what are programed into FS2k2 (rare occurances - only happen to me twice. This was compared to my dad Jappesen appoarch plates).

Ok here is the simplified procedure I use.

1. About 50 nm, I will set my primary VOR to the ILS freq. and tweek the OMB button to the EXACT magnetic heding, then turn on the beep. I move whatever Navaid I was using to the second VOR.
2. Once I have the localizer locked on, I keep a close tab on the distance on the DME (Distance Measureing Equipment). Remember to have the DME source selector swithed to VOR 1. I usually get a lock on before the ATC give me the final vector for the approach. (Hint - when you first do this, it is easy to get turn around so use the GPS to give you a visual situation picture, but try to ween youself from it later on.)
3. Once I am on the final vector and within 20nm, I watch the vectical needle deflection. I shallow the intecept angle to less than 20-30 degree once the needle is 3 dots from the center. You will learn how to this only form experience so dont get discouraged.
4. When your DME show you are within 10nm, fly the glide slope and mind your appraoch speed and proceedure. Dont become preoccupied with chasing the vertical needle to much. As your get closer the needle becomes more sensitive as you will notice. Rule of thumb 10-5nm, 1 dot of deflectiong is ok. Under 5nm, half dot of deflection.

The most important thing to remember about an ILS approach is that it is only designed to get you within a reasonable distant and oreintation to the runway to make a VISUAL before committing; not to place on on the paint in 0/0 IMC (0 visisbility/0 ceiling). In real life, pilots unabled to get a viz on the runway are spun for another attempt or another airport with better conditions.

Well I hope this help
