Woa! Thank you for such a quick responce Pete and thanks for writing such a wonderful program that has bought my cockpit alive :)
I might have to have a look at LUA to fix my issue.
The problem is absolutely that for some reason arming the A/T does not disengage or ignore my input pots. I believe that FS9 does ignore the inputs once the A/T is armed, but FSX does not. I have also read some documentation that PM will disable the inputs by using 310A, which makes sense as PMs MCP does not use FSX's built in MCP.
My setup is as follows:
My input sensor pots write to offset 089A and 0924 respectively. If i disconnect the servo's and leave my input sensors engaged then place my physical throttle in the IDLE position and then arm the A/T and put it in TOGA mode I can see that as the virtual throttle advances to MAX and as i move my physical throttle near the IDLE mark, the virtual throttles jump back to IDLE again and then try to move back N1. So hence i get this fluterring. If i connect my servos and disable my sensor inputs for the throttle and arm the A/T.. i have no problems. If i have both the Servos AND the inputs connected and i assign a temporary button to set bit 3 of 310A, this works and disables the input throttles from writing to the throttle offsets. This however is not an elegant solution as I loose a button and i must remember to press this button before a press the A/T button.
My understanding is that 089A copies its values to 088C until 310A bit 3 is toggled. So i believe when the A/T is armed FSX does not make 088C read only (if thats even how it works), so as my physical throttle moves to catch up the the virtual throttles it overwrites these offsets with its current position and i get this fluttering.
Again i do not have any software that i can write logic in... IE when A/T is armed set 310A bit 3, so I may have to rely on LUA. I was hoping though if this was a common problem you may include it as a feature request :).
Thanks again
