I've been spending alot of time recently flying in IMC, and is it just me, or are some of the ILS glideslopes/localisers not in line with the runways at some major airports?

I just tried an approach into EGCC, and I was consistently guided in several feet to the left, and I always seem to be at about 100ft when over the threshold.

Has anyone else noticed a similar problem at any other (default) airports?

There's a quite a few offset localizers

Hi Ric

There were quite a few offset ILSs in 2002 so I guess they were passed over into 2004

Obvious solution is to check out the problem ones with AFCAD2 and see if you can modify em to suit. Couldn't do that with 02 but it's easy with 04

Cheers guys....glad to know it's not just me then! I though I was going loopy!

Yeah some of the ILS beams are not 'perfect'.
Though some are not certified for total 'whiteout' conditions.

All ILS systems have to meet certain criteria in the real world. They all have to be accurate. It's the aircraft themselves that are certified at Cat I / Cat II / Cat III minima, which is the deciding factor in what weather they can land in.

It is possible to have offset ILS systems.  Some airports have instrument approach systems, but they are offset due to buildings, mountains, etc.  These are not great for 1/4 mile visibility conditions.  Innsbruk and Ronald Regan have offset ILS approaches.  So it might not be a bug in FS9.

Sorry Its just the fact that the ILS systems say if they are cat II, III, or I in the sim.
Im sure that the ILS beams vary in category too.

Don't forget to press + to correct your altimeter.  Just a few millibars difference can give you false readings of tens or even hundreds of feet.

Oh and theres no substitute for your own two eyes  8)
