Looks like you are searching the same sites I am!

Following the advice above, the Piper AP is in the recycle bin for now and a newer Century AP installed.Works just lovely!

Last picture for the day... think this version will last me until the Carenado update.

Hmm I think I too have that Century gauge, what update do you mean? Are they making another patch?

They've said they are looking into the problem.. my guess is that we are going to see an autopilot fix.But in the meantime, this is a very capable and somewhat similar autopilot, so I'm in no hurry tosee a fix.. :( The more I fly this plane, the more I like it!

I think I might see the problem y'all are having with the autopilot.I havn't tested yet but this is how I think it works.Nav and GPS seem to work fine for their holds. So lets say you set a nav hold and engauge the autopilot. Next (Don't use the ALT hold) just use the rocker to adjust pitch. You will see your trim wheel adjusting pitch automaticaly.When you engage the autopilot it automaticaly trims for your current pitch angle or some kind of default pitch.Now if you turn on the ALT hold on then turn it back off the rocker will adjust your vertical speed normaly and the trim whele will not automaticaly move.Set your rocker for your vertical speed and once your within 25 feet of the altitude you want turn on the ALT hold.On a side note I also have sent an e-mail to carenado. Seems the sylinder head temp gauge functions but the needle only moves a small amount then stops moving even when the cylinder head temps are in the 300's it reads around 200.Anyhow I hope this helps y'all use the autopilot. Enjoy. :(

Thanks, I'm going to try that!In my search for documentation, the closest I've been able to find is this:http://www.centuryflight.com/manuals/CENT41.pdfor thishttp://www.centuryflight.com/manuals/68S1024.pdfThis is for the Century 31 and 41 unitsQuote:When engaging the autopilot, the aircraft will maintain its existing attitude. The Pitch Data Modifier is a momentary type rocker switch, located on the right sideof the Mode Programmer, used to modify the airplane's attitude and to shift the APfrom the ALT mode to the ATT mode.

On a side note I just looked at the airplane.cfg and the default pitch is 700fpm and that seems to be what happens if you turn on the autopilot. I think the pitch for a climb of 89knots is around 7.6 on the pitch whele for about a 15 degree climb.Also here is a little cheet sheet I have made for the plane. Some of the numbers might be off a bit. BTW I know it's the PA-34-200T. I just noticed I did the attachment with the wrong name. :( Oh and one last thing on the cheet sheet. The top of decent calculation as listed is wrong but I forgot to change it for others since I made this for me. It should be.Altitude - Altitude to decend to * 3 = Top of decent. So for example if you want to decend from 10000 to 2000 feet it would be:10000-2000=8000*3=24000 Drop the 000 and you want to decend 24nm from the location. Then if you want to know how fast to decend look for your ground speed on the GPS. Lets say 150knots ground speed:150/2=75*10=750 feet per minute. So you would want to decend 24nm from the airport with a decent rate of 750 feet per minute. :(

On a side not I'm not a real pilot and one this I don't know is when should I transition from a normal climb to a cruse climb? (Not trying to hijack the topic)

I am not sure I understand the question-but normally if using the autopilot you would engage the attitude mode which allows you to use the rocker to pitch to the climb rate/airspeed you desire. As you approach your cruise altitude you would pitch to level with the rocker-then engage alt.Hope that is what you were after.

No that's not it' It has nothing to do with the autopilot it's self. I understand the autopilot.What I am asking is say I take off from an airport in the PA-34-200T The settings for best rate of climb is 89 or best angle at 76knots. Say I am climbing at 89knots. The service celing is 25000 feet however I'm not going to be able to reach 25000 feet with an 89knot climb. However the cruse climb settings of 2450 RPM and 31.5in. HG will climb to 25000 easily. So my question is when would I want to change from the initial climb setting at around 2575 RPM's and staying under 40in. HG to the cruse climb.

I think I understand the autopilot-but I think it is something possibly different. I suspect (cause I have done it myself) that Carenado did not make a custom autopilot gauge but instead used fs king autopilot gauge. Therefore this is why the rocker is not operating as I would expect but is doing as you stated above-selected a climb rate. I could be wrong-it will be interesting to hear what they say.As for your other question-I can't really comment on turbo as I have never flown one. However- cruise climb which gives better cooling and visibility is usually transitioned as soon as it is safe to do so.

ok thx. That is what I wanted to know. So I should treat the initial climb settings as something to clear obsticles and obtain an initial climb speed then transfer to cruse climb. I guess I will have to rework my fuel consumption on my cheet sheet for cruse climb settings then. :(

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?

I wanted to let eveyone know I have a fix for the cylinder head temp gauge on the Carenado PA-34-200T.I don't want to upload a modified cab because it is their info however if you know how to make a cab file and edit XML just replace the 2 lines below with these new ones. I have sent my fix to carenado after many e-mails back and forth.The 2 files are ALCYOIOIFU_L_gauges.xml ALCYOIOIFU_R_gauges.xmlOriginal <Item Value="200" X="147" Y="7"/> <Item Value="460" X="238" Y="7"/>New version <Item Value="93" X="147" Y="7"/> <Item Value="237" X="238" Y="7"/>My only modification was to convert from celsius to farenheit.You can check my numbers with this formula.degrees celsius * 1.8 + 32 = degrees farenheihtdegrees farenheit - 32 / 1.8 = degrees celsiusone last thing. Converting back to celsius might be a bit off I did round down in my code.

After seeing your modification, I had a look at the Autopilot.xml file and tried the following changes(L:TRIMAP,bool) 1 == if{ (>K:AP_PITCH_REF_INC_DN) }and(L:TRIMAP,bool) 2 == if{ (>K:AP_PITCH_REF_INC_UP) }Bingo, now the autopilot works the way I would have expected.I've also sent this to Carenado via e-mail.

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