AP Disconnect During Flight

Recommended Posts

I'm trying to track down what may be causing the issue, but this also may be a result of my configuration of trying to get the Honeycomb Yoke to control lights via FSUIPC.

 

Since there's no profile yet for the CRJ, I decided to use FSUIPC to setup macros, assigned to the Honeycomb yoke switches to control various lights. All works fine, but the flights I had after I set these up would disconnect the AP during flight, and I would then not be able to re-connect the AP until I was below 8000ft.

I did assign the right side yoke red button to be the AP disconnect also as a macro, but I hadn't pressed it. I tried 3 different flights, and all have had this same behavior. I'd take off, and climb out, get to cruise all with the AP engaged and functioning normally, until I either make an altitude change or enter the arrival details in the fmc. It's at that point the AP master will disconnect. The individual buttons still light up (HDG, ALT, Speed), but I can't get the AP Master to reconnect until after I get below 8000 ft. 

Is it possible FSUIPC is sending some odd data causing this?

Also, I notice that after setting the FSUIPC axis assignments to the Logitech Throttles (1-Throttle, 2- Spoiler, 3- Flaps), If I'm starting up the engines, and then set flaps to flap 1, the engines move up to full power (the VC throttle controls aren't moving). I have to manually move the Logitech throttle level up slightly to regain control of the engine throttles and bring them back to idle. 

 

Appreciate any insight into what may be causing the problem. Thanks

Do you fly with real weather and have strong winds? I've read several reports about people who have issues with all kinds of aircraft (A330, PMDG 748 and so on) suddenly losing ground speed and even becoming uncontrollable due to high winds that suddenly jump about 180 degrees back and forth. This would explain the autopilot disconnect.

Regarding FSUIPC I have to apologize. I currently don't use that. Neither in P3D v4.5 nor in v5.0.

Thanks Hans, I'm using ASP3D with real weather. The flights that had this issue didn't have strong winds. At some random point during cruise, the AP would just disconnect. No matter what I do, the only I've found to reconnect is to drop below 8000ft. I don't have this problem in any other aircraft, and even in the CRJ, it's only intermittent, but more often than not. 

I will say I think this only started after I installed and started to use the ASP3D Beta. They've been having issues of their own where the sim would CTD at random points. I'm hoping when a more stable release of ASP3D is out, the AP disconnect problem will stop.

On the positive side, it definitely keeps you alert and tests your skills!

Did you try to reduce the AP Disconnect sensitivity on the EFB Options page?

 

Thank you for this Hans. I just had an autopilot disconnect using CRJ V1.0.2.0 in P3D V5,  which I assume occurred due to high winds using ASP3D Beta #7. I will try the same flight and reduce the AP Disconnect sensitivity.

AP Disconnect sensitivity is only about yoke input by the pilot. It doesn't change the sensitivity to winds.

CRJ V1.0.2.0 in P3D V5

You mean 2.2.0.0.

1.0.2.0 sounds more like the A330 (although that one got an update to 1.0.2.1 yesterday)

Yes - thank you for correcting me.

Wanted to bring up this issue again - I just finished a system hardware rebuild and a full P3d 4.5Hf3 reinstall with all addons.

 

I'm having this problem again where the CRJ AP disconnects above 20k and will not reconnect at all - when I was previously having this issue, I could reconnect the AP when I went below 10k, now it won't reconnect at all. 

This isn't a sensitivity issue from what I can tell. I was able to fix the problem when this occurred for me months ago by setting the IRSs to ATT. Not sure why when they were set to NAV, the AP always disconnected above 20k. 

Now, after I've done this rebuild, that fix doesn't work for me. Regardless of how the IRSs are set, AP will disconnect every time, above 20k.

There's no difference between IRS NAV and IRS ATT. I just checked that in the code. However, the autopilot will indeed disconnect if the IRS is not aligned. Which alignment settings (EFB options page) do use?

Same here. So that's not the reason. Do you have any external software running that interacts with the CRJ? I remember that there was a Virtual FO available at Simmarket, for example.

Don't have any virtual FO (FS2crew), but I am using FSUIPC for a Honeycomb yoke, logitech throttle and rudder pedals. All controls are 'passed through' to p3d standard mappings with the exception of reverse thrust, which is a button map to 'thrust decr' w/continuous repeat, release is set to thrust cut.
