I have the Simon Topman Panel installed for Airbus 310.The master autopilot on/off switch will not engage. Therefore, the autopilot (speed, altitude, heading) will not work.Also, the enginges cut out whenever the overhead panel is viewed. I was able to find the answer to this problem You must cold start the plane. Then you can change back and forth between the main panel, and the overhead panel without an engine shut down. YOu must start the engines according to the prodceedures outlined in the texture patch A313st20_Patch.zip.However, I cannot solve the failure of the AUTOPILOT MASTER SWITCH to be turned on. Does anyone have any solution?Thank you.Stanner

These need to be ON before the autopilot can be engaged.I had the same problem with Beno

The answer is that you must: 1. cold start the engines according to the Simon Topmann instructionsfound in the patch to the original panel file.2. the generators must be in the off position, after start up3. the two yaw dampers and two pitch dampers must be in the on position.If the above is done, then you can switch back and forth from the main and overhead panel without an engine shut down. Also, the autopilot master switch will then operate.Stanner

If somebody has Simons instructions and can email me, I would be grateful. I have some excellent Airbeese here that I cant fly for lack of a check list!!ThanksEric Joinerejoiner2 AT Bellsouth.net

Topmann has two sets of instructions:1. On the aircraft itself which are in the original panel download.2. the instructions on how to start up the engines, which are located in the Patch to the panel instructions Both of these files are in Avsim under the author's name Simon Topmann.Stanner
