Okay I am at wits end, I have tried all night to Autoland my 737-800 on the runway at Gatwick. I selected the 26L ils approach Timba1D, i put in my flap refs in teh fmc approach page I input the ils freq 110.90 in both ILS dials on the radio stack i dial in 10879 into the hgs, I dial in 259 in bother course dials on the mcp I then monior the flight as it approach the turn to est localiser, I'm at 3000ft and descending to 2000ft to lock onto the ils as per the gatwick ils chart i adjust flaps etc as required I click on the app button on the mcp and then the course dials suddenly change to 079 which is the course for the 08r runway. as I reach 5.5 dme where the glidescope begins i click cmd b but it only stays on for 2 seconds and i click it again and cmd a goes off and i click cmd a to put it on and cmd b goes off. and after that lets just say it wasn't happy landings.I have tried it at least 5 times and each time was a complete failure

Hi Red,I'm fairly new at these more complex sims, so I might be completely off the mark, but is there a possibility that runways 8R and 8L are the active ILS runways, and not 26L and 26R, and tuning to their frequencies gives you information for what is required to approach those runway headings? Doesn't the ILS frequency of the runway itself remain the same in both directions and it is just up to the pilot to know that, and the ATC and ATIS to inform of that?As I said, I could be totally off the mark, but it would seem to me that if ILS frequencies were different for the reciprocal headings of a runway, that would be a LOT more frequencies to have to slate out :)

That is quite probable.Also, if you dont press VOR/LOC and capture localizer, APP mode wont arm. This can be changed from options menu in FMC.

Hi do you have Just Flight Traffic X installed? If so this could be the problem. If that's the case go to their site and you will find a simple work round, look under support for "

After installing Traffic X, I am experiencing problems at particular airports/airfields"

No. Each runway has it's own freq. In this example there should be four ILS frequencies as long as all four runways are ILS equipped. The only time one strip of pavement "share" a frequency is in the case where one direction is ILS and the other is localizer back course. But a back course does not utilize glide slope, only the localizer. .

Please someone correct me if I'm wrong, (I don't have the intro manual on my iPad) but the option you are talking about it to allow the GS to be captured before localizer. I don't think LOC/VOR ever has to be used to "arm" APP mode. APP mode can be used directly as soon as the frequency is tuned. To answer the OP, are you above 1500' AGL (radio altitude) when activating the second AP? Also, you must have captured both the GS and LOC and be in APP mode. I think you also have to have the gear down and flaps set to whats on the INIT page as well, but I'm not sure about that one. What I'm getting at is, it works for me every time I've tried it "by the book." If it's not working for you, something isn't set up correctly. The tutorial is good to follow to get properly set up.

Ok,I was just curious because he said that he selected ILS Runway 26L and that the ILS Frequency is 110.9 and I created a flightplan that ended at Gatwick ILS Runway 8R and it's frequency was listed as 110.9 as well... Just to check, I looked at an IVAO website that listed both 8R and 26L with the same frequency as well; 110.9 and also indicated that both runway directions were ILS equiipped...

I think you'll find that 08L/26R are for emergency use only and are normally only used as taxiways. Which is why you'll probably find that most RW SIDs and STARs only feature 08R and 26L....In fact, I recall some years ago a RW pilot trying to land on one of 08L or 26R and getting into a lot of trouble as a result.If you look at your charts, you may also notice a certain lack of approach lights for 08L/26R:—Anyway, that's probably why you're having trouble landing on 08L. :( Cheers,Brian

This was actually discussed here once, it ended uo being some AI traffic add-on messed up the files.

See my post 4 for name of AI traffic add on. Rwy 26L at EGKK is affected as well as 9L at EGLL and 9 at EGGP.

On the contrary, in the UK it's common for a single runway to have the same ILS frequency at each end. Obviously in real life only one ILS is switched on at any one time so there's no conflict. I've never had a problem with FSX getting confused by this, but as someone said it may be 08R was the active runway.The NGX sets inbound course automatically as a help to users, but this aid can be switched off in the options so you can set the course yourself. That would prevent the course being overridden while on approach.

Except he says he was approaching 26L....Sometimes FSX ATC directs you to land or depart from the emergency strip. I got around this by installing third party Gatwick scenery, with AFCAD which doesn't class 08L/26R as an active runway.

Okay having read the posts I have uninstalled Traffic X and I tried landing at Gatwick 26L again and for teh first attempt tonight it worked!!! I shall never buy anything from Just Flight again!! Thanks for the help guys!! I can now enjoy my PMDG 737NGX again.

Red Star I too have Traffic X and have it installed with the following fix:

"Please go into your FSX settings menu and select

Scenery Library

A list will appear, containing an entry called

Traffic X Airport Facilities

. Untick the entry to disable it, click

OK

to save the changes."

Taken from the Just Flight Support page

Since doing the above I have not had a repeat of the problem so if you still want to use Traffic X just reinstall and do as above and you will have no problems

as i am landing every day at Gatwick i can surely tell you that 26L is active and has an ILS. Daniel.

Get Ultimate Traffic II instead - I much prefer it.
