Hi, I have a doubt about the coding of the A / P disengage that is present in the MCP of the Boeing 738.
It seems to me that the big lever, present under the CWS A and CWS B buttons, relative to the A / P Disengage is a "switch".
However in the figure present in "Panel and Instruments Layouts" relating to the MCP (Collins) B737-8 this switch is associated with "AP_All_Disengage" which is managed as "buotton". It's correct? In my case it doesn't work, but it doesn't even work by associating it with the "AP_Switch" parameter.
Thanks for the attention.
