Massive Bug At Nice

Featured Replies

I've got the Nice airport the comes with the Eurowings package and it does it too, even with the new afcad. Are you using the default Nice scenery? I thought the afcad determmined where the ILS beam went.billg

I have this problem with the Simwings scenery of Nice (tried a bunch of AFCADs). Luckly when I flown there the weather has been pretty good and I just hand fly the landings.

Are you sure that this is not a case of an offset localizer?? What does the published approach chart show?? Paul

Are you all sure that it is a bug? Many localizers are offset, usually because of terrain considerations. They bring you down, perhaps through a valley, until you can see the runway, then you make a visual landing. I don't have a real-world approach plate for this airport but I'll bet you can find one on the Web.Oh, and as to this being the only airport with this "Bug," that is not true. Try landing at Castelgard (sp?), British Columbia. The localizer must be a mile or so off to the right of the runway; you come in right beside a mountain peak at about a 30* angle to the runway. when you see the runway you make a left turn from the ILS to line yourself up with the ruway. Not all ILS are precision approaches.R-

Coincidentally, I happened to fly into Nice earlier today (Simwings version) and the ILS was, as usual, way off. Luckily the weather was fine.I have all the real-world charts for Nice and, whilst there is a lot of info regarding the terrain, landing procedures, Circle-To-Land, etc., nowhere is it mentioned that the localiser is offset like it does for, say Innsbruck on its charts. The charts show the headings of 04L and 04R as 045 and 043 respectively.The AFCAD shows the headings of 04L and 04R as 044.9 and 042 respectively.Pat

Remember Kai Tak (Hong Kong)? The localiser and glide slope gave an 080 deg approach to Rwy 13 which was aligned at 135 deg. A 55 deg turn to port had to be made at the middle marker, when the aircraft was less than 2nm from touchdown and was at a height of about 600ft above the runway. A Missed Approach was mandatory if visual flight wasn't achieved by the Middle Marker.The final approach was over Kowloon City and the following picture ISN'T retouched!The runway projected out into Hong Kong harbour and China Airlines managed to put a 747 into the harbour.

I cant see any reason why it would have to be off centre though, the approach to the runway is perfect, its just sea apart from the odd bit of coast that might jut out, so maybe it is something of a bug.

I think this a well known issue at Nice and I believe there is a file fix for it right here at AVSIM library (look for "Nice fix" or some such thing). When I first landed a long time ago using an FMC and LNAV, I landed several hundred feet off-course.JS

The DAFIF ILS chart for RWY04R says "Localizer offset 1.9 deg. Final approach course intercepts rwy centerline at thld"My AFCAD shows the LLZ located between the two runways. RWY04R is 42 deg, the LLZ is 44.910 deg and on my screen the LLZ does intercept the runway at the threshold. The result is that you will be offset to the right on approach intentionally.It seems accurate enough to me and not a bug, though I've just noted who started this thread!

Well, look at the charts and AFCAD again. 4R ILS final approach course, based on what you say, is definitely off set from the runway center line in comparison to 4L. AFCAD shows both runways having a MAG course of 45.9. For the ILS approaches, the headings are 45.9 and 43 for 4L and 4R respectively. The AFCAD numbers you quote are TRUE headings, not magnetic--you forgot to apply mag variation (I just checked). Mag variation is shown in AFCAD as -1--which is notation for WEST var in the sim and AFCAD. Therefore, subtracting a minus is the same as adding one degree to a TRUE heading. And mag heading, NOT true, is what is shown on the Approach Plates and is used in the sim--the sim applies the mag variation.Paul

And I noted several people agreeing with me......

WillG,I agree with mgh - the ILS is deliberately offset for that runway. When I first bought the Nice scenery I questioned the offset and was told this is how it is in the real world.It doesn't matter how many people agree with you. They are misinformed I'm afraid. Perhaps a question on the SimWings forum might have been prudent before posting here? http://forums.simflight.com/viewforum.php?f=112Cheers,

>And I noted several people agreeing with me.........and if they all agreed the ILS had been abducted by aliens, it wouldn't add any weight to the argument :)Official Nice airport information is available in this pdf file:-www.sia.aviation-civile.gouv.fr/aip/enligne/METROPOLE/AIP/AD/2/AIP%20FRANCE%20AD%202.LFMN.pdfLook at the foot of page 6 and you will see the exact location of the ILS navaids, and note (3) points out that the ILS is not on the runway axis.Happy landings :)--Bryn

hmm i didnt think we had escalated to an arguement yet, I just wondered why it was like this.

hello WillgNo one is arguing yet, but no doubt you will start one soon.You asked why the ILS is like it is and now you have the answerThis is how it is at the REAL airport.But i doubt if this will be good enough for you and you will be backdisputing the evidence of the real world approach plates.By the way i thought you were going to do us all a favour and delete your account ?, Oh sorry i forgot that will be in your next postif past experience is anything to go by.
