RNAV-Approaches possible with King Air?
-
Hi, I'm using the PMS50 GTN 750 Professional. Today I tried to fly the RNAV App into LOWI 26. Sadly the aircraft does not capture the virtual glidepath. Yesterday I tried a RNAV App into EDHK, and it worked well. It showed up "CPLD", which I think stands for "coupled". Maybe it was luck, that it worked yesterday. What do I have to set up for these kind of approaches? Is there a manual for that?
Thanks, Philipp -

oday I tried to fly the RNAV App into LOWI 26. Sadly the aircraft does no
Same problem here.. I can't fly an RNAV procedure with this aircraft. I also cannot fly an RNAV procedure with the Asobo stock King Air either.

Thanks for your post. I tried it today again and it seems as the switch for „GPS-Approach“ should be in the yellow „armed“ position and not in the green „active“ position. After doing that, it worked well, localizer was shown right and at the fap the aircraft started to descend on path.

Well, I can say that I'm jealous that the RNAV works. I'm glad that it is for people. I still have an issue.
My procedure:
- Load and Activate RNAV procedure into GTN 750
- Be in GPS mode and use NAV to follow magenta RNAV waypoints
- Ensure altimeter is set correctly
- 1 mile before FAF, activate APPR
- Be at or slightly below published FAF RNAV Altitude
Observations at RNAV FAF:
- Glide slope diamond is way below and not coming from the top as it should be.
- I fly right by FAF and no descent occurs.
ILS procedure work for me
If anyone has 10 minutes to spare, can someone try this quick flight for me? Fly the RNAV runway 36 procedure for KOXC and airport in Connecticut USA. Start Take off from KHNV runway 20 which will lead you nicely turning right toward KOXC runway 36. Takes about 10 minutes to do this flight. Thanks for he consideration!

Seems there could be an issue. Tried this approach with the C172 G1000, works OK. But not with the Analog King Air and the Analog C208: descent is not initiated at FAF. However when I turn away and then back to the DAAVY FAF, something "triggers" and the autopilot begins its descent, and then follows the approach correctly.
Am using Navigraph and the PMS GTN750 (free) in case it matters.

I forgot to mention that the RNAV approach I detailed works with other aircraft that use the G1000xi. It specifically does not work with the King Air 350. It could be pilot error on my part but I ran that approach over 10 times for RNAV and none worked. Neither does the reciprocal runway RNAV.
I made sure the approach was activated
I checked my baro
checked and was at correct FAF altitude
Armed RNAV 1 mile beforeAnyway, thanks for trying for me :)
