Deviated VORs, ILSs and Airways in FSX

Loud_Silence · 11-26-08, 01:25 PM

As you may know, an airway that starts from a VOR in the heading 080, for example, will go over the radial 080 of that VOR. But almost all airways i've used in FSX are way off course! For example, if i fly over the radial 080 of some VOR, with no wind or anything that could change my course, in reality im flying heading 083 or something like that!
Also, ive found some ILSs with a deviation up to 4 degrees. For example, if the runway is headed at 090, the ILS makes you fly at 094 and things like that. I also've found more ILSs wich go paralell with the runway...
These things are totally messing up my IFR flights. Anyone knows something about this bug or if there is a patch to fix it? Thanks.

I can't say I've experienced/noticed this. Are you taking the magnetic variation between true north and magnetic north into account?

As for the ILS, some runways actual courses are a bit different than their names suggest. For example KORD (<--pdf link) runway 4R's course is 44.3 degrees, not 40.

I'm not sure why an ILS would guide you in parallel to a runway unless the runway course is entered into the autopilot incorrectly or the scenery doesn't match up right.

If none of the above is the case, could you list the add-ons you're using and/or some more specific examples(airports, runways, planes)?

I hope this helped.

Try the VOR LAX at Los Angeles Intl. If you're over its radial 100 and then you fly straight to the vor, you will be flying heading 102. Check in in an AC with a glass cockpit for better precission.

Wait, I don't understand, I thought the only point of Non-Combat flight simulators was to do stunts in Jumbo jets? :p

Hmm, you're right. I checked LAX with several planes on several radials and they all were off by 2 degrees to the right. X-Plane doesn't seem to do that, so it's not a problem with our flying...I dunno then, anyone else have some input?

It is, but being 2 degrees off could really fubar an A380's back flip in the grand canyon.

There's also a ILS in KSFO (san francisco intl) going nowhere. If you follow it you will end right into one of the hangars.
In LEMD (madrid, spain) the runway 33L ILS is slightly deviated to the left, it ends at the runway but the beginning is offcentered.
