autopilot does not engage

[alexzar14]

The latest 1.7 update resulted in the plane grounded. 1 hour flight preparation and take off, and than the autopilot wasn't able to engage. AP-A doesn't engage, AP-B engages but does not track LNAV, VNAV, VS or HDG select. 

I have removed all plugins and kept only FWL, SkyMaxPro and a couple necessary ones  coming with addons - ground handling that comes with JAR A330 and Gizmo. No FSUIPC, no tug master. Version 1.7 doesn't like FWLua or A330 ground handling?? Please advise.

Check your null zones. Try raising them.

Yes, seems to work.
