Encountered this when both 747 & 737NG flights attempted into KMDW. Only Localizer is showing on approach and the GS shows up AFTER the approach ends and the plane has cruised past threshold overflying the runway.Does anyone here have the answer?ThanksDennis Robart

I do.

I do.

But of course you do- but will not provide it :)Hmmmmm....

With such skimpy information it is impossible to even speculate what went wrong. You have to show us your route of flight in relation to the runway,altitudes plus how you control your AP. My hunch is that you are in a wrong place/altitude.

Did you notice that 31C and 13C use the same ILS frequency? Now ask yourself how FSX knows which ILS approach you want to use? Obviously, the one that is closet to you. Now I am only guessing here since, as Michael has pointed out, you have given us very little to go on, but would I be right in thinking you are approaching Midway in such a way that 13C is closer to you the 31C? So when 109.9 is tuned in, the ILS for 13C is picked up?

Paul,Why be a sarcastic smartarse? Obviously you are the font of all knowledge and expect everyone else to be as intelligent as yourself. The bloke has just asked a question and would like to know the answer without being basically ridiculed.Andrew Dixon

As my post title indicated, I approached 31C, not 13C, so my question remains- Why is only the other direction's GS working or showing up?Thx

Also- this is FS9 here that I am using-

TisacThe critical question is what approach are you using to get to the outer marker of RW31C? As Paul stated both RW use ILS 109.90 so check your FMC to ensure that as well as the frequency, the runway heading is also entered correctly. Apart from that I don't really know why this is happening.Andrew Dixon

In FS9 by default backcourses ILS/LOCZ on on by default. As you work your way around the pattern you can get the incorrect ILS/LOCZ unless you are within just a few degrees of the extended inbound center line. You can verify this by looking at the ident in the PFD annunciator.The fix is in these instances to modify the AFCAD layer with the ILS properties and turn off the back course. In a few cases this can also happen in FS9 where adjacent runways share the same frequency in opposing directions.For reasons explained in another thread it is best to use the payware AFX or ADE9X freeware editor to avoid some errors that can occasionally occur with AFCAD if you are modifying an add-on airport.Search the FS9 forum here for references.

I just flew this approach perfectly in the 744... Took off on 4R, looped around to the south along the lakeshore and then intercepted the GS just fine at 5000 feet at HILLS... You have any custom sceneries installed that might have messed with the ILS there?

KMDW is default, scenery wise as I have it here, and all the other sceneries that I do have work fine. FSDreamTeam (KORD), Cloud9 (don't recall what scenery it is), and ImagineSim (KEWR)sceneries, besides FlyTampa (SEA & SFO). Autolands have been successful in SFO, DFW, SEA with no glitches showing.

Add- KJFK scenery here is FSDreamTeam, and autoland also works there too, no problems showing.

Was ILS RWY31C programmed into your FMC, or did you manually tune the receiver (744)? My FSNAV lists 31C as being 109.9/315, but that's with the FlyTampa scenery. Actually, landing the 744 at MDW would be pretty exciting. Set that autobrake high, brother!Cheers, Chris D

I overran it haha.

Tisac has been asking a bunch of similar ILS based questions on other threads, and everything has pretty consistently been someone elses fault. It is even someone elses fault that he couldn't or wouldn't try to follow a tutorial flight, since it was perfectly obvious in his mind that he could not possibly be doing something wrong.

Paulie baby, just to let you know- the ILS at KMDW as it exists in my FS9 has a glitch- the GS does not show as available in 31C approach only shows up on 13C, which I have successfully made to autoland- No, I didn't overrun, either- Let's see you do it :)
