Here we are again...the VS function on the KFC224 doesn't work. The display will change, but the unit doesn't alter the pitch accordingly to achieve the desired rate of climb. This has been the case on all the Carenado planes since the F33A (except the Skymaster, which has a totally different AP). Can we please get this fixed?

Kurt, have you got my AP code for the Baron? And would you willing to try it in this airplane? ...assuming it is the same code. BTW, we are talking about a KFC225, right?

Yes, the KFC225. The fix you did for the Baron works great, but the panel coloring doesn't match.

As you can see, I do not have this plane - what panel coloring are we talking about?

Just tried it again, and the VS mode works as it should. Every click on the up/dn buttons increases or decreases the VS by 100ft/min with the A36 immediately responding.....with and without the FD

I agree with Mr. Stolle, the VS mode on the AP activates and, if a new altitude was set before, you can alter the commanded VS in steps of 100ft/min with the UP/DN buttons.

The stock AP does NOT work for me as advertised. I can adjust the rate of climb command after selecting VS mode, but the aircraft does not respond to the changes. This was the case on the Baron, as well...until Bert's fix. He can tell you what he did to facilitate that. I've got a working KFC225 now, by creating a folder with the contents of the autopilot CAB, and replacing the XML file with Bert's tweaked autopilot.

Why should someone want a 'fix' for something that's not broken? Seems to be a system specific problem but not a bug with the plane.R U using FSUIPC, custom add on hardware etc.?This 'problem' just doesn't exist on my system with standard FSX controls.

Bernt, If I thought it wasn't broken, I wouldn't have suggested that a fix was in order. Hardware: Nothing custom -- CH Flightstick, CH Pedals, CH Throttle Quadrant. Calibrated, in this instance, through FSUIPC (I'll check tonight to see if that makes a difference.) For the record, with the exception of this one small gripe, the A36 is about as close to perfect as it gets. The Aspen EFD1000 alone is worth the price of admission, and your contribution to the flight modeling is deeply appreciated.

Kurt, maybe the behaviour only shows up if the VS mode gets entered in a certain way. I always manually climb to cruise alt and go to ALT. Later, I dial in the lower altitude and press VS and adjust the rate. With that very limited use of mine, the VS rate gets regarded and the plane accepts all entries and follows them. So my point would be that every other scenario of entering the VS mode may hold a flaw or may not, I haven't tested it.I never used it on the way up so far, so maybe you can describe what you are doing exactly to trigger it and I will report back if I can see it too.This may also help Bernt and/or Carenado if there is a flaw in the AP.

Fully agreed.

Sorry for jumping in, but since I actually wrote some of the autopilot code, I can confirmyou are entirely correct. The exact sequence you describe works, and if that is the wayyou use the autopilot, you are going to be OK. The confusion arises when you read the Carenado documentation which indicates thatthere is a Pitch and a VS mode that you can use to climb or descend. This is indeedthe case in the real KFC225! If you are flying in ALT hold mode and set the altitude knob to a higher altitude, youenter Pitch mode and the aircraft will start to climb. The UP and DOWN buttons willgive you a higher and lower Pitch ie climb rate. So far so good...If you then hit the VS button, you might expect that you enter VS mode..The UP DOWN buttons now indicate Ft/sec, but they have no influenceon the climb rate any more. This is IMHO a bug, and I've submitted updated code to Carenado who has chosennot to implement it. So, I've offered up the new code to whoever wants it, andsome users have taken me up on the offer. If the Carenado implementation does everything you want it to, there is no reasonto "upgrade". Otherwise, send me a PM with your email address..

Thanks, Bert, much appreciated description. That's something I haven't tried so far.I don't own the Baron, so this Carenado KFC225 is a first for me. Thanks for the PM/email offer. I will test it on my next flight and come back to you if the flaw is present on the fine A36. A big thumbsup.

Confirmed. I've cruised at around 6500ft, set 8500 as new target, adjusted the pitch (which worked) and then activated the VS mode.Then, as you can see, I commanded some positive and negative rates to trigger a change, including e. g. -700 ft/min, but the pitch remained on the setting from before activating the VS mode, the commanded VS rates were disregarded. When leaving the VS mode, the UP/DN keys had an impact on the pitch again, as expected. So the VS mode seems somehow flawed when entered that way, as Bert says. By the way, thanks for the YD fix again. It's working fine! Now I'm hoping for someone to confirm the temperature display offset on the Aspen which, so far, is a great gauge.

Ok, I see. Basically you can presently choose between climbing in pitch or VS mode. Furthermore you can start in pitch mode and switch to VS, but once you are in pitch mode you can't switch back to VS.I didn't notice that during testing because like IRL I always use either one or the other mode but I don't mix them, sorry about missing that.Concerning the temp, I tried now everything with pitot heat on/off, advanced animations on/off etc...Can't get any difference to appear. Can you test with ASE off as this does some weird things concerning weather....

Thanks for your testing on both issues. No need to apologize for anything in my eyes. Not at all. I've posted the temp thingy in the other thread.
