MSFS: Using the KLN 90B GPS / Black Square Duke / Microsoft Flight Simulator

In this tutorial, you'll learn how to use the KLN 90B GPS developed by falcon71. This GPS unit from the 1990s made its debut in the Beechcraft Duke by Black Square, and we can expect to see it added as a GPS option in more planes in the future.

An amazing feature I missed that falcon71 told me about is that while entering the waypoints on the FPL screen. you can simply press ENTER on your keyboard instead of exiting KYBD mode each time. No need to reach for the mouse. Just press ENTER after typing the waypoint, and ENTER a second time to confirm the waypoint information.

Thanks for the information. It’s nice to have the reminders about all the steps that make the flight simulator an enjoyable experience.

[@lifetimeadventures9107]

A very well done video. Your tutorial explanations are very helpful when flying in the MSFS. Watching your video brought back memories of using the King avionic units in the airplanes that I flew in the my past piloting years. 👍🛩️

[@joel77703]

Super clear tutorial as always. I love how you can see the progression in tech from this through the 430 and 530. In the original manual for this unit they spend what seems to be a crazy amount of time explaining what a cursor is. Obvious now but probably not in 1992 or whenever this unit released.

[@wyntje83]

love it! respect for pilots dealing with this type of GPS before the invention of modern display and inputs.

Hello Kip, what a very interesting explanation of this KLN 90B GPS, I have never delved into it, but your explanation invites you to delve into it. Thank you for the explanation Kip.

[@ozboy53]

Thanks Kip, an excellent video on the KLN 90B well done, and for the "Pressing The ENTER key" update.

[@SimPicks_real]

Mega video, thank you for that one. Love the KLN90B.

Finally someone is actually using an interesting and unique GPS :) This is a perfect tutorial video, thank you very much!

[@paulb267]

Thanks for doing the video, much appreciated.

Does the VNAV calculate a direct to for the waypoint you choose or does it take your current route into consideration which would be more track miles? Saw this piece of unit as a highlight of the Duke release, didn't know it was coming to the Comanche before your video. Cant wait! 😻

[@KipOnTheGround]

VNAV is calculated directly to the waypoint you provide it. It does not take the rest of the route into consideration. Just had to test it to make sure :-)

[@mrmisterno1]

Oh really? What about the GNS 530? Been using vnav on that a lot thinking it's smart enough to take the flight plan into consideration.​@@KipOnTheGround

[@Rahhhhhnman]

Great job Kip, no-one does these instructional videos better than you.....imo

[@MojaveHigh]

Well done, learned a lot, detailed but still easy to follow!

[@johnnykaercher5358]

What a great and instructive video!

[@GumperVanLier]

Excellent, Kip. Thank you.

[@LHA675]

So big thank you for the Tutorial :))) Regards from germany.

[@garysmith5256]

Thank you, tremendous video!!

[@yams900]

Well done mate ! Thx for sharing :)

[@LayneBenofsky]

Now this is retro gaming. Nice! :D

[@mikecoffee100]

Yoo Kip what I have done I went and baught the The Piston Duke so thought why not try using this older navigation aid. I thought Loran was an old aid . Thank You for this lesson

[@KipOnTheGround]

Nice! The Dukes are so good and the KLN is really fun. It'll be awesome seeing the KLN in more planes soon (A2A said they'd be adding it to the Comanche). Nice change of pace from the modern stuff for sure

[@kutyafal]

Great tutorial! I was wondering what the right inner button's push-pull SCAN function is for? I could never figure it out.

[@josehtcm]

Thank you very much!!, great tutorial, I learned a lot, easy to follow! Where I can find more info? Thanks.

Sweet

[@haga2000]

Exellent video; I have probaly done somthing wrong in the setting, when set for GPS the HDG light is always on even if the AP is ofF, and HDG light is also on when NAV is turn on and the autopilot do not follow the leg any advice?

[@KipOnTheGround]

NAV won't activate until you fly close enough to the active leg. Just use HDG to fly towards the course with NAV mode on (armed/standby). Once you're close enough, NAV will activate and follow the course as expected.

[@haga2000]

@@KipOnTheGround no, this is not the case for my i am in a flight right now and on the course (accoring to nav 3 window on right side) the nav light is on so is hdg AP is in GPS mode and EN-leg but the AP do not guide the plane only adsjusting with hdg works??

[@haga2000]

the yellow HSI arrow middle line do a left right jumping motion?

[@haga2000]

@@KipOnTheGround i found the error, by accident the falcon folder was twice in the community folder and inside another folder , and i also had v.1.1 no it works an is updated to v1.1

[@KipOnTheGround]

Glad you figured it out, cause there was no way I'd have guessed that one :-)
