Afternoon, Started using the new Fly2High scenery for KHPN when I noticed the ILS for runway 16 was showing I was way too low vs what the PAPI was showing. I removed their scenery and confirmed with the stock scenery that it’s showing the same. Please see my screenshot for reference. Thanks for any insight! ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/8/0/800297436a2b4129cb3f4bc77209616bdecdf8a2.jpeg) ---

Hi, good afternoon, Thanks for your report. I can confirm it, and it has nothing to do with 3rd-party or stock scenery. I seem to have made a small calculation error. I will fix this in the next couple of hours and will release a second revision, as this issue affects all glideslops worldwide. Some less, some more … I will keep you informed when the new revision 2 is online. Thanks again for your valuable and good report! Cheers, Richard ---

Revision 2 is out… please open the Hub, update to AIRAC 2606 revision 2, and try it again. It should be better now … sorry for the mistake! Here is the approach to KHPN ILS16: ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/f/9/f95185d4a535d4c38860034de73ec2c51a650c74.jpeg) Thank you, Richard ---

Richard, Thanks for the reply! I’ve updated my nav data, but still showing super high on the GS. See my attached image. I checked it with the stock scenery as well with the same result. It seems the GS is fine 1.6nm out, but once I get a bit closer as seen in my image, it’s off considerably. Thanks Richard! ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/4/d/4dedd51eca114f9ef2076da7eb7afea168322333.jpeg) ---

Hi, Thanks for your testing, much appreciated… I have adjusted the pilot-eye height and the glideslope, and I guess I have found a good real solution for that. For me, it looks much better. Tested in the C172 with the G1000 and the upcoming AIRAC 2606 revision 3: ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/7/7/77c643a176efa1c1947a62bd275e38aefff5593c.jpeg) ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/3X/6/0/60f840e7d3efd3804cb8786ab9f65566c36763ad.jpeg) I will do some more tests, but I guess it looks good … Cheers, Richard ---

Hi again, I have uploaded revision 3 now - we have developed a brand new and more accurate method for the glideslope calculation. We ran a lot of tests over the last 2 days, and we think this is much, much, much better than before. Please install revision 3 via the Hub and let us know your results. Thank you very much, Richard ---
