## Real Life ILS Question

I am not a real pilot but hoping to be someday, but I was just wondering if the ILS leads you to the actual touchdown point on the runway or does it lead you to before the runway where the actual radio thing is... I had this discussion with my math teacher who flies helicopters and I am still confused about where the ILS actually leads you, he seemed to believe that the ILS will lead you to the actual radio thing which is before the runway starts, but in FS2002 you can plot the ILS approach with boxes(I think its called EFIS) in which it does lead you to the correct touchdown point on the runway. Anyways, sorry if this question may seem dumb or if I am just confused. Any advice from you real pilots who fly real ILS approaches would be great.

Thanks,
Chris

They're designed to lead you down to a point 1,000 ft. down the runway after the threshold.

There are actually two separate transmitters for an ILS. The localizer (horizontal guidance) transmitter is at the far end of the runway, on the centerline. The glideslope transmitter is just off to the side of the runway, 1,000 ft or so from the approach end. And, as Silverblade says, touchdown point is about 1,000 ft. beyond the numbers.

There's 3 ILS category:
Category I. An instrument approach procedure which
provides for approaches to a decision height (DH) of
not less than 200 feet and visibility of not less than
1/2 mile or RVR 2400 (RVR 1800 with operative touchdown
zone and runway centerline lights).
Category II. An instrument approach procedure which
provides approaches to minima of less than DH 200
feet/RVR 2400 to as low as DH 100 feet/RVR 1200.

Category III. I forgot about this but this category will allow a/c to autoland, and auto TAXI <G>! yes, some Big airport have this facility!

You can find the detail on FAR, ICAO regulation, etc..

But that's in real life, for FS2002 i think it's category 2.
