Hey Folks:
I am having an issue with the trim wheel in the 737 NGX. When I add any kind of power to the aircraft, be it ground power or engines running, I know that the trim wheel needs it to work correctly. However, when I turn the power on, the trim wheel resets itself to 14.50. If I try and move it back up into the correct take off setting in the green and as instructed by the FMC, it just moves itself back down to 14.50. Any ideas what is going on with this. Any help would be great. Thanks
Dean
