Bert,Where is this Autopilot.xml located. I've searched the whole drive and not found it?Thx,

I actually need some help on this from someone who knows how to program XML... please contact me via PM if you can!To start with, I looked in the panel.cfg file and found that the autopilot is called PA34SEN!autopilot.The PA34SEN gauge is a cab file which means it can be edited.Since I do not like to keep creating cab files while I am testing, I extracted the content of this cab file into a subfolder tothe gauges folder and named this subfolder PASEN34. I renamed the cab file to .old just in case.Now, FSX loads the PA34SEN gauges from the folder, which means that I can make changes to the xml files in this folderand test. Problem is: I know very little if any XML. All my programming skills are Fortran based :( What I would like to do, is make the autopilot behave the way it is described in the Century Pilots Guide.Changing the Rocker Switch from activating the trim to activating pitch incr/decr is a step in the right direction.When the AP is first switched on, it appears to activate a Pitch hold (I assume this is FSX default).This allows the rocker switch to do it's thing. So far so good.When I activate ALT it holds altitude. OK.When I release ALT, it does not revert to pitch hold as best I can tell, so the rocker loses it's function.Turning the AP off/on restores the pitch control.So what I really want to do, is re-activate pitch hold when the ALT is released, but I do noteven know the XML syntax for multiple events on a mouse click... help!

Although I am not an expert in any way on XML code I will give this a shot and see if I can get the pitch hold to activate since the code should already be located in the power switch for the autopilot it shouldn't be hard to find. Not sure if I can do anything about the 700fpm default setting till I look at the code.

Initially, the pitch hold mode is set by FSX:>From the SDKdefault_pitch_mode This determines the default pitch mode when the autopilot logic is turned on.0 = None1 = Pitch Hold (current pitch angle)2 = Altitude Hold (current altitude)If no value is set, Pitch Hold will be the default.Here is what I would like to be able to do: (pardon the faulty XML syntax)<Click><Value>(A:xxx,bool)</Value><Case Value="0">0 (>K:...)</Case><Case Value="1">0 (>K:...) 0 (>K:...)</Case></Click>

A word of thanks to all the guys working this AP problem. I am sure the problems are forwarded to Carenado for an official fix."I don't have the nerve to dig into XML files etc. .. "Your efforts are much appreciated .. :(

OK, I think I've got it.This is what I sent off to Carenado: <Click> 0 (>K:AP_ALT_HOLD) (A:AUTOPILOT ALTITUDE LOCK) 0 == if{ 0 (>K:AP_ATT_HOLD_ON) } </Click> </Area>Pitch hold is automatic when the AP is first turned on (FSX default), and forced back on when the ALT HOLD button is turned off.

Looks good but where in the file did you put it? Kinda hard to tell on that one without a refrence.

Bert-thanks for your work here. Fortran-sounds like you are two years ahead of me-I was machine lang and basic 1.In any case-hopefully we will have a real working autopilot-they are very particular and model related-glad to see we may get some reality here...I hope..

Just a quick note I heard back from Carenado today and they sent me this fix for the cyliner head. It should be slightly more accurate then my version because of the decimal places in my conversion.Change this line

Has anyone figured out the Carenado Seneca autopilot?Does it have any kind of attitude hold when the AP is switched on?And when and how does the UP / DOWN rocker switch get used.Lastly, on my AP anunciator, the NAV and ALT readouts are on topof each other.. is this a bug? Or does it work correctly on yoursystem?

Geof, it has actually been a lot of fun trying to program something in a language I have no real experience with..Thanks to lots of help on various Avsim forums (and a most helpful contribution by my son who is fluent innewfangled computer languages), I've been able to also add the last and hopefully final feature andsend it off to Carenado for their consideration.The autopilot now matches the Century 31 Pilot's Guide in it's function, in that the rocker switch adjusts pitchand will switch ALT HOLD to ATT HOLD, if ALT HOLD is active.

Bert-sounds great-thanks for your work! You don't happen to own the Duchess also? (I have a whole list of "improvements" for the Century IV in that bird).

No I do not... and maybe that is a good thing, since my to-do list was put on hold for a few days and urgently needs attention :(

Yeah-flight sim tends to do that. :(

I was looking a little deeper into the gauges. Is it normal for the Manifold Pressure and RPM gauges to be off by as much as what is displayed? Looking at the popup I get a different reading then the guage.The RPM gauge shows: <Position X="152" Y="154"/><Item Value="0" X="84" Y="298"/><Item Value="15" X="152" Y="7"/><Item Value="26" X="282" Y="224"/>So if I read this right I see X=152+152=304 Y=154+154=308.152 would be verticle(center of width) at 7 pixles from the top so this number is correct.This would mean eigther the 1st, 3rd or both are off by a small amount.I think I have a more accurate calculation.X= 0+ 97= 97 Y=308-35=273 (RPM 0)X= 0+152=152 Y= 0+23= 23 (RPM 15)X= 304- 43=261 Y=308-92=216 (RPM 26)Let me know what you thik. I'm going to pluig in the numbers and see what happens.My numbers seem to be a little high so far. Hmmm. I just noticed that the image is not 304x308. It is 304x304 making the numbers off.
