Hope I'm not getting too pushy, but can anyone figure out why is this happening: My A/P is configured LIKE THIS, EXCEPT for the fact that "alt hold" is not activated, instead the wheel points to "OFF", and still, I can't use Control Wheel Steering function, can't change V/S by using yoke while A/P on, the plane won't listen to the yoke while the "elev" paddle of A/P is engaged no matter how much pressure input is on the yoke. Is there some switch I have to...switch? Or maybe the bad luck still hangs on me like a limpet...

Thanks in advance!

Just disengage altitude hold, then you will be able to climb or descend. (switch at the right)

When you switch altitude hold to on, the autopilot will maintain the altitude you're at.

 

Hope it works now!

 

I have a manual called on the Sperry 77. I think it's from Avsim, but can't seem to find it, will try to send it via a Private Message.

 

Best regards,

The OP did say ALT HOLD is off when he tries to alter pitch.

 

It always worked for me, although I now use the updated A/P (similar to the 737-400).

 

Do you have a registered (ie paid for) copy of FSUIPC.... this is required for everything to work.

I use both SP-177 and SP-77. I got a registered version of FSUIPC v3.70...maybe I need a newer version...I don't know, but anyway, I can control V/S with the AP...disengaging "elev" paddle of AP than manually changing pitch, than reengaging "elev" paddle of AP will do it, AP will maintain the new pitch angle...but it's just not realistic...

Make sure that in the FSUIPC misc tab, the three "Assorted facilities" options are UNchecked (center elevator on AP trim change, disc elev trim axis for AP, and reverse the elevator trim sense)
