Thanks everyone for your help! Really appreciate it ! Just one thing I want to share. When I tried taking the plane for a flight again I ended up pressing ALT Hold by mistake. I turned it off and pressed VS hold and just like that it started working again! So I tried this a couple more times and it turns out that If I press VS hold after ALT hold, the plane starts ascending and descending according to the vertical speed I input. No problems at all! but I'm really starting to think that VNAV or LVL CHG is a better option.

Thanks for the help Christoph but after takeoff I usually turn on speed hold so my speed is automatically controlled. I do monitor my speed to make sure the auto throttle is working fine. I'm not entirely sure on how to properly use VNAV so I just stick to V/S

It actually does read CMD when I switch on the autopilot. But for some reason, even though VS hold is activated and it shows on the PFD, the aircraft goes into either a dive or a stall.

hopskip FD does show on the PFD. could you elaborate on what you were saying?

aside from the trim, any other ideas why the aircraft is dipping? the VS hold is set to 1800+ and as soon as i turn on CMD A the nose starts dropping. i do a manual override and bring the nose back up but when i engage VS again, the plane lifts its nose and goes into a stall.

im pretty sure i set takeoff trim properly. i'll try turning off REALISTIC A/P ENGAGEMENT.

Hey guys! i'm new to the pmdg 737 and i've done a couple of flights with it with no problems whatsoever. Recently during a flight, just after takeoff, i turned on heading select, speed hold and vertical speed hold but after turning on the master autopilot, the plane's nose starts dropping and i start losing altitude, so then i have no option but to manually bring the plane back up. this has been going on for some time and it's really irritating. any help would be greatly appreciated. thanks !
