New V 1.0 Fokker 50 for XP11 having issues with vertical speed and holding altitude. The vertical speed adjust and altitude select arent adhered to with the autopilot. The aircraft will continue to climb and sometimes descend. Eventually I can get it to hold altitude by manually adjusting controls and then engage altitude hold. Cant get alt select to funtion like it should.

Same here, can't hold altitude. Just bought the aircraft. Are the developers active on this forum?

I had similar issues, but only on 2nd flights. On my 1st flight the autopilot would usually work just fine. Today I discovered that this dataref gets set to 0 when selecting the "STBY" button, which I press after every landing: sim/cockpit2/autopilot/electric_trim_on

Since it never (as far as I can find) gets set back to 1 the autopilot loses the ability to control the trim wheel. To fix it I wrote a small lua script (to be used with FlyWithLua):

DataRef( "trim", "sim/cockpit2/autopilot/electric_trim_on", "writable")

function trimfix()
 if trim < 1
 then
    trim = 1
 end
end

do_every_frame("trimfix()")

Thanks for this script. Old post but recently moved everything over to 11.52 Vulkan with same BS. Script works like a charm. Thanks
