Caravan Autopilot - won't disarm?
-
-
@Black-Square I think one or more of these fixes might have had unintended consequences.
I noticed flying the Caravan this morning that the AP will now adjust the held altitude based on the cockpit altimeter and not its own. I was holding at 7000ft with a setting of 30.23 (or so, the Kollsman window is impossible to read), when I pulled a local altimeter of 29.94 and adjusted the cockpit one first.
The plane began climbing back to 7000ft as soon as I touched the altimeter but the KAP140 was still set up 30.23. Adjusting that had no effect, but I did discover that playing with the KAP140 Baro setting is still doing something under the hood because you will get all Alt warning beep if you set it differently enough; about .3 in either direction, which IIRC is roughly 300ft.
-
I suspect that's because the Working Title autopilot is missing some features of the native one. For example, it has no bank angle limiter. I added this in my modifications I sent them, so hopefully it will be added in SU15. The KAP140 is my only autopilot with a separate barometer, so I'm not surprised I haven't noticed, given that the Caravan was released well before the WT GNS. I'll take a look next time I have the sim running and see if I can spot a mistake or improve their code.

I really appreciate the offer, but please take my word for it that it's extremely unlikely that any of our changes would have resulted in that change. I just don't want to waste your time after you were so willing to help my troubleshoot the bigger problem. I will give this a test run on my side later. It's very easy for me to roll back those changes, because I keep a copy of every version of my aircraft exactly as they were released to the public. If I need any further testing, I will let you know, but I will also do my best to spare you the trouble. Thank you!

I did just do a clean install, and it did not work as I thought it did; my apologies. Normally the altimeter change hasn't been as wild as it was during today's flight, so when I adjusted it I saw a small wiggle in the VSI and thought it was adjusting.
I'm not really surprised that the changes wouldn't have done it, but I was sure (so much for that) that it was working previously. You said it's missing some features of the native one? Maybe I had seen it in action when using the stock Asobo avionics.
-
@Black-Square Yes I can also verify in the BKSQ Analog Caravan, the KAP140 Baro setting doesn't have any effect on the altitude hold, only changing the altimeter Kohlsman does.
-
I just confirmed that this doesn't work with the default C172 with Asobo's implementation of a KAP140 either. When I looked in the code, it's using the SimVar "INDICATED ALTITUDE" directly, which will only look at the main altimeter, not a secondary barometer. It's deeper in the code than I usually like to make modifications to, but I will look at the documentation and see if there is an easy addition I can make and suggest to Working Title.

@Black-Square Always appreciate your quick response on these forums, by the way I also had the "AP will not shut off" issue (in WTT mode) and your suggested fix (change Flight Director =1) resolved the problem, though I had to map a key to toggle FD on/off since there is no such clickable button in the actual Analog Caravan visual cockpit model.

You shouldn't need to do this, the normal Autopilot Off/Disconnect has been working fine, both bound and clicking the yoke button.

Now I feel really bad for the bum steer!

Nick, do you know if any of this made it into the SU15 build? I know the "hot swap" fix did, wondering if any of these other items did, as well.
I will almost assuredly be asking questions in the relevant parts of the forums in the coming days, but just playing around in the Dukes to get my controls squared away, you've outdone yourself this time. Just starting the engines and watching the diagram on the tablet has me giggling like a kid.
If half of these features make it back to the TBM, I might never buy another plane from anyone else ever again. Bravo, and congrats on the release!
And now back to the Caravan.

So glad you're enjoying my aircraft! I know that when I chuckle in delight at what I've created, I figure at least a handful of other people will feel the same way :)
Yes, the tablet will be coming to the TBM! I've already made the tablet for the Starship, as well. I'm glad you're looking forward to it.
Unfortunately, none of the other improvements I sent them have been added to the WT GNS. Very sorry! You know that I usually like to send code for instant improvements to my users, but this one is a little out of my control.

You are building the Starship? 😱🤯

@Black-Square Hi Nick, I'm a huge fan of your Velocity XL (possibly THE biggest fan), and I'm anxiously waiting on hearing whether you plan on updating the Velocity with the new G3X in SU15? Pretty please? As far as I'm concerned it's still the most fun GA aircraft to fly and I looked at a bunch of others but nothing can top it for me as far as performance, looks, speed, things to do in flight and ability to land on absolutely any airstrip. The G3X has always been its only weakness (including the slightly cut off MFD screen), I will spend many more quality hours in that aircraft if you update it.

Indeed, I have now almost completed the unenviable task of programming all the avionics in the Starship. It's been a painful process (and around 20,000 lines of code) of learning just how far ahead of its time the Starship truly was. You can expect to see some screenshots in a development update soon.
I will definitely return to the Velocity soon to make these improvements, so I want to make sure that those who appreciate that airframe as much as I do are still able to enjoy it to its fullest!

Hi @Black-Square
i read these postings with grate joy. I appreciate your fast response and help.
For me these corrections in the files helped me also the kepp the AP running. So far a realy grate model you have created.
But i need to proof @ultradianguy right:
Perhaps there should be a pinned posting with a summery of all changes in the configs until the update has been released.
It took me several Hours to find all the postings to fix my AP issues.
Hope I could make my point with my poor english ;-)
Kind regards
