been looking for a solution for this for a while
the managed vertical guidance mode just wont engage no matter what i do according to the manual you push Alt selector but just aint working no matter what combination of pull/push on both alt/v/s selectors. the white managed guidance dot never appears on the FCU, the ALT autopilot button never illuminates.
The MCDU has been programmed with waypoints and height constraints so no problems there. FD is selected.
i tried replacing FSUIPC.dll as i read it helped someone with this problem before buy it not workig for me.
Tried reinstalling JF A340 prof buy still no luck
Any help appreciated cheers.
