LOWW - ILS (Glide Path) bringind a/c too high on THR and vs PAPI


I was wondering if is possible to check the “location” of the GP path for the ILS approaches in Wien, all of them are always bringing me pretty high over THR and quite over the PAPI angle. I do expect to cross the THR at around 50ft, instead I’m almost always over 150/200ft above ground there, this brings me to decide or to ignore ILS before (not doable in foggy weather) or to almost miss the touchdown zone…

I do have also the Payware LOWW scenery from Gaya, but as far as I got the “ILS data” should still be part of Navigraph package. Correct me if I’m wrong :smiley:

Thanks for the support

Hallo, is there any new about my above inquiry?

This will require some testing on our end.
Ensure that you have the newest cycle installed. Double check altimeter setting, just in case.
I will do some testing.


Hi Andrea,
sorry, I have overread your posting - sorry … additional to Jason´s comment, please try the approach without the Gaya scenery also, means only with the stock data because normally, 3rd party scenery´s are higher in the priority as our package, which means the ILS information will be used from the 3rd party scenery and not from our files.

Therefore, if possibile - remove the Gaya scenery temporary and try the same approach only with the stock scenery but with our data :wink:


We are testing and will get back to you soon.


Thank you guys!

About QNH and latest cycle I confirm they are always right.

I do have to try with/without Gaya if are differences (not tried sincerely). Not sure when I’ll be able (maybe in a week or more).
If something comes from your testing please let me know.


Hi Andrea,
first of all, thanks for your patience but this glidepath issue is time consuming to test.
We have released revision 2 for 2110 now, where we have tried to improve the reported glidepath issue.

Please, can you update your cycle and can you try the approaches again, if this version is better now?

Any comments are welcome :wink:


Super, thank you!
I´ll try this weekend the new AIRAC version and keep you posted how it behaves in Wien on my side.

Very good day Nav. team!

As far I tried the GPs in Wien are better working. I was unable to try all runways in this weeked as I have time onlz for few flight (online) and with real weather, wind was quite strict to use other options. Buuut I can tell you that RWY 29 looks better in therms of path and reached height above THR (and aimed Touch Down point).

I’ll test further in the upcoming days, up to you if you prefer to already close the topic from now on (worst case I open a new one) or wait a bit more.


Good morning Andrea,
first of all, also I/we wish you a good start in this new week - thanks for the very warm “hello” :wink:

Also, thank you for the feedback and all your effort on this. We have also discovered, that this solution now looks much more better than before on different places on the earth …

So, don´t rush, take your time - I will let open this topic till we have a final ok from you to close it :wink:

Have a nice day & thank you again

I took a bit more time, but I had several chances to test all RWY (even with SU7) and I can say: Well done guys! All GPs are bringing me at the correct height at THR and allowing me to respect the touchdown zone properly (at least in Wien).

From my side is a good to go also to close my issue up :slight_smile: and thanks again!
