So far nothing worked.  The plane AP will not hold the plane keeps pitching upward.  I tried the AP before letting go of the stick, but it will not engage.  It only engages when I am pushing slightly downward on the stick.  I am also having difficulty understanding the tutorial on trim and how to set it to the airspeed in the FMC.  I can the trim manually and brought it down to 2.5 before take off, but it did not work either.  I noticed after take off and during the AP disengage problems,  the trim is at 6.

Reread my post #12!

 

You dont engage the AP before letting go of your stick.

It is done the other way around (as I described in post #12).

(Unless you have selected the PMDG option (in the CDU) that the AP can be engaged at all times. (see my post #2)).

 

I also already told you to disregard the trim function.

It is not correct at the moment. PMDG is working on a fix!

(again see post #12).

 

 

What you should do is unplug your stick and try a flight with keyboard keys only.

I know, boring, unrealistic, etc etc.....

But do it just once!

FMC programmed correctly.

Lnav, Vnav armed and V2 in the speed window.

Click TOGA.

When you get airborne, then at 400ft enage the AP.

You will see the AP works just fine and that it is your stick in combination with your manual inputs that are messing up the AP system.

Rob,  Sorry,  there were quite a few posts I was working from trying to trouble shoot.   I did test the stick as you suggested,  I just did not explain correctly what I was doing.  That did not work.   BUT,  I also unplugged the joystick and that did stop the AP disconnect!  I only use the joy stick for taxi, take offs and landings anyway.  What I did was after I took off,  I paused my computer and unplugged the stick, and it stopped the disconnect.   It is not a big deal for me at all having to have to do that since I don't use the stick during flight anyway, just taxi, take offs and landings.  

 

Sometimes I have to unplug the joy stick anyway because on occasions my various aircraft, for whatever reason,  they will pull hard to the right while taxi after I load the aircraft at an airport.  But when I unplug the joystick and replug it, then the plane moves straight.  I got use to that and not a big deal.  It does not do that all the time, just occasionally.   I tried this method with the 777 AP as well.   After I unplugged and replugged the joystick during flight,  the AP held!  I am glad that fixed the problem!

 

While testing the 777,  I tried Delta and United.  I noticed United has runway call outs but the Delta did not.  Both tested at KSFO.  These are both from the PMDG Operation center liveries.   Could I have accidently disconnected the call outs somewhere for Delta airlines?

 

Thank you for the helpful suggestions and I greatly appreciate it!

Your welcome ofcourse.

 

Your detailed explanation makes it seem like your stick is broken to me.

I mean if it gives sudden uncommanded hard right signals.....that is not normal.

If you can, the obvious thing to try would be another joystick.

 

At least you found a work around, I mean I could not live with it, but if you are ok with it than that is fine ofcourse.

 

If you use FSUIPC, then you could still try to delete the FSUIPC.ini file. This has fixed all kinds of different problems! (back the .ini file up first, and you then have to re-assign the stick axis).

And you can try to update FSUIPC to the latest version.

Rob,  It is a little hassle having to unplug it, but a minor inconvenience.  But what is most important to me that it does fix the problem, especially with the 777.  Speaking of the joystick,  I was having problems with my Level-D 767 with the A/P for the past 2 months.  It would not engage at all and point skyward until it stalled.  (I had the 767 for 3 years and it worked fine). I just could not figure out what was wrong.  I even reloaded the Level-D 767 to no avail.   This evening, I decided to unplug the joystick at the start of the runway for the 767 and after 2 test take offs, the AP would engage after selecting it.  Perhaps the joystick is broken regarding the AP.  The AP works fine though in my QW757 and PMDG 747-400 & 8i without any issues. Perhaps the joystick defects only reacts to certain add-on aircraft.  The joystick is 7 years old.  You giving the clue by informing me that it may be my joystick is not working is possibly the answer!   Thanks for all the help!

Maybe a stupid question but did you use CH manager to calibrate the Yoke?

 

Also, when in calibration mode, does it show you input while you don't touch it?

I am not familiar with that.  What is the "CH manager" and "Calibration mode"?

Well I don't have the PC available for some time so this is out of my head.

 

With the CH products there comes a software package called CH control manager or something like that. In that program you have the option to calibrate your control devices.

 

I have used this calibration to fix the slight left rudder input on my pedals for example.

 

You just have to do this once untill your hardware is reinstalled. Try it out, it can't harm.

I purchased a new controller, or a joystick and it fixed the auto pilot problem for me.
