    Hello everyone. In anticipation of the upcoming release of the Black Square Dukes, version 1.0 of the open-source KLN 90B has now been released:
    https://github.com/falcon71/kln90b/releases/latest

    This project has been a labor of love for this old and clunky, yet very capable GPS unit. While the device is horribly outdated these days, I hope you too will feel that mastering it, is a very rewarding and unique experience.

    Version 1 was developed solely based on the real manuals and some videos and photos I found online. I'm sure there will still be bugs left and cases where the KLN does not behave exactly like the real unit. If you have access to the real device or if you notice any differences, please reach out to me. My goal is to have a pixel perfect replication of the real unit right down to the bugs the real device may have.

    I have created a Discord server if you need help, have any feedback or just want to talk about the KLN 90B:

    I would like to thank Nick from Black Square for his trust in this simulation, his valuable feedback and his patience in getting the integration just right. It has been a pleasure working with him and I am excited to see his excellent Dukes releasing very soon now with support for the KLN 90B.

    With version 1.0 and a fully working implementation in the Dukes, I no longer expect any breaking changes. If you are an aircraft developer and would like to integrate the KLN 90B into your aircraft, feel free to contact me. You will also find further information for integration in the wiki: https://github.com/falcon71/kln90b/wiki

    Here is a link to the real manuals of the KLN 90B, if you would like to be prepared for the release of the Dukes:

    I wish you a lot of fun with the KLN 90B and the Dukes!

    Very true! I also wish they had added a few more realistic GPS options such as a single GNS 430, a single GTN 650 and perhaps the excellent freeware KLN90B.

    Best request it on the JustFlight forums. I guess the KLN is still under the radar. I hope this will change once the Dukes are released and people can see what it's like. Version 1.0 of the KLN is ready to go and stable for developers, I'm just waiting on the Dukes here.

    I know, this is a stupid question to ask of a weather program, but has anyone tried if the visibility works correctly?
    The visibility with the default live weather is always half of that of the METAR and it has ruined many non-precision approaches for me.
    If this is fixed in Active Sky, then this alone would be a reason for me to get it.

    Thanks guys for your input, this clarifies a few things.

    I still find it strange, that anything less than 9999 means an automatic go-around for any non precision approaches. As I said, I kept an eye on this for the past weeks and I'm sure its not airport blending. Southern Tenerife was in a dense fog all the way to the sea. Here is another example at VNKT, the runway is 4km long:

    The METAR was stable at that time, there are no other airports nearby and the whole valley was filled with fog, this is not a low cloud. I hope that Ambient Visibility in the debug menu would give a clue to what is going on, but it seems kind of unrelated to the perceived visibility.

    Does any one else have this problem with the visibility? If so, I will file a Zendesk ticket.

    How do I interpret the visibility in the METAR correctly? Let's say the METAR reports 9000 meters, I was under the assumption, that I could see 9km in either direction.

    I had to go around at the minimums a few times lately. Whenever the METAR is not 9999, the fog appears quite dense. I made a habit of checking the perceived visibility when it is not 9999 and came to the assumption, that MSFS interprets the visibility as the diameter instead of the radius. In other words, the visibility is halved.

    This screenshot was taken at GCTS this morning, the runway is 3.2km long for reference. The visibility here looks much closer to 4.5km instead of 9km to me. Does anyone know which interpretation of the METAR is correct?

    Confirm it doesn't show a magenta VNAV indicator to the *left* of the altitude tape?

    It does show. But for me, it shows the VS deviation. When I'm above the path and I pitch down to the target VS, it shows on track, even though I would be still above the path. I was expecting it to still show that I would be above the path.

    One thing I'm very surprised nobody is talking about, is the VNAV deviation bar. For me, it seems to only show the deviation of the current VS to the target VS. Based on the FCOM, I understand that it should however show the deviation to the VNAV path in feet (Like any other aircraft). I can fly above or below the VNAV path and the FMC also never shows any significant deviation. 
    Did I understand the VNAV deviation bar wrong, am I the only one with this issue or do you all just live with it?

    But what is even more interesting is the Bendix KLN90 GPS - can one input Google Maps coordinates as custom waypoints into this device after converting them into the DMS degrees, minutes, seconds format?

    Yes you can. If it is in the real manual, then it is simulated, including custom waypoints of all types, which are saved persistently.

    So will Milviz use that mod under the GPL  and so commit to ensuring it remains compatible with future MSFS versions and feeding back any changes they release to the open source codebase ?

    Or perhaps once more they'll just slap in some default MSFS avionics and put a paragraph on the manual saying if you want to try using the mod you can but they'll do nothing to help ?

    I was not approached by Milviz/Blackbird, so I do not know their intentions. But yes, either of those options is available. I just hope that they are aware that there is an accurate open source KLN available if they have not developed their own solution.

    If they want to properly model a KLN900 that's great but honestly I will not be surprised to see Milviz stick in the default GNS530 (maybe with a Bendix King style facia).

    The KLN 90B is available for aircraft authors here:

    https://github.com/falcon71/kln90b

    The KLN 900 is very similar to the the 90B and I would be willing to make the necessary adjustments to simulate the 900, if there is demand by aircraft authors.

    This is available now, would like to see it in the PMDG DC-6 or upcoming Pilot's Dash 7.

    https://msfsaddons.com/2023/05/29/the-return-of-a-classic-bendix-king-kln90b-gps-now-available-for-msfs-aircraft-developers/

    It appears that the Dash 7 used the KLN 900, not the 90B. There are only tiny differences compared to the 90B, so it would certainly be possible to create that device as well. However, I would first like to make sure the 90B works bug free and see if there is actually any demand from aircraft authors, before starting with the 900.
