April 5, 20215 yr Since a couple of months VNAV does not angage anymore. Any idea what the reason could be Thanks Paul12 Herbert Werni
April 5, 20215 yr The reason is likely how you set up the aircraft which prevents VNAV from engaging according to real world logic of the systems. Have you changed something in operating the plane? Are you doing anything differently than before? I don't know of any bug in the NGX that would prevent VNAV engagement and there was no update to the product/nothing was changed from the developer's side, which is why it's probably user related. In any case, we need some more information. In what situation does it not engage? How did you set up the aircraft?
April 5, 20215 yr Most likely your elevator axis is not centered and you have not configured the 737 to disable real-world autopilot connection behavior.

April 23, 20215 yr I had similar problem in FSX. I flew from SLLP El Alto to SLCB Cochabamba with PMDG 737 and suddenly disengaged VNAV and the plane lost control. I saw a warning light "Stab Out Of Trim". What happened? https://drive.google.com/file/d/1tnyWF5v5SV4VQUtAhmrpOb5Nqkdks0Bt/view?usp=sharing Patricio Patricio Valdes
May 1, 20215 yr Nice video. I can see you're flying about in the low speed warning zone. Had that once when an F/O tried to expedite climb at ATC request with the pitch wheel. Autopilot disengaged the moment it started flashing. I took control and smoothly sorted it but he was a bolshy sod and needed a lesson as he was ignoring my advise. No danger whatsoever I might add. I'd not let him get that far. Mark Harris. Aged 54. P3D, & DCS mostly. DofReality P6 platform partially customised and waiting for parts. Brunner CLS-E Yoke and Pedals. Winwing HOTAS and Cougar MFDS.
