when adding A/B to a plane that did not have them, you must also make an entry into the panel.cfg that adds the corrct gauge for throttle control.
Try this: Make a backup copy of your panel.cfg and then copy this into the panel.cfg of the aircraft you are working with, change the [Vcockpit.XX] to the next number in sequence, if there are no [Vcockpit.XX] entries then it would be [Vcockpit.01]
//--------------------------------------------------------
[VcockpitXX]
Background_color=0,0,0
size_mm=1024,1024
visible=0
pixel_size=1024,1024
texture=$dummy
gauge00=F22_Gauges!DSBAburner, 1,1,1,1
gauge01=F22_Gauges!vortices, 1,1,1,1
Good luck, and let me know the results.
