This loads the Turbine Duke without the clicking sound on my setup (P3D v4.5): Start P3D. On the start screen (not on the runway at Eglin), change vehicle to the Mooney Acclaim. Still on the start screen, select your departure airport and location on the field. Load the scenario and keep the Mooney's engines running. Change to the Turbine Duke. As in all things flight sim, your mileage may vary.

Does your throttle or joystick have controls for prop and fuel mixture? Make sure they're both fully pushed in (or turned up or whatever). At the cutoff setting, the MD11 engines will shut down when you try to apply the throttles for the first time. Charles Nadeau

Shutting down ASN and starting it up again midflight got rid of the flickers for me.

In my case, the "black bar" FS2Crew panels seemed to happen after installing the Airbus service packs. The panel.cfg file would get new window objects at positions 20 to 25, which created duplicate entries for the windows used by FS2Crew listed at the same positions. I deleted the new window entries and it seemed to fix the panel conflicts.

Might also be a hardware problem with your throttle. Kyle (scandanavian13) has a post somewhere explaining the technical details, but an early descent puts you in Hold mode -- basically manual thrust. If your throttle is pulled all the way back at the top of descent, you'll go into a dive unless you take over the throttles. Try a VNAV descent without DES NOW or touching the throttles. Pull the throttles all the way back before starting the descent. Charles Nadeau

It's not pretty but one solution is to save the flight, restart FSX, and reload the flight. Worked for me when I ran across the problem tonight.
