MCP1 (Original) Question - Knob 'B' Values

[ScotFlieger 280]

This is an important question for VRi MCP1 (original) users.

 

The MCP Combo page lists settings for the Knobs for + and - rotation broken down into 2 groups A and B. For example,

 

-- EFIS MINS knob

MINS = {

["A SHOW"] = A172_EGTref_show  ,

["A  +"] = A172_EGTref_inc  ,

["A ++"] = A172_EGTref_incfast  ,

["A  -"] = A172_EGTref_dec  ,

["A --"] = A172_EGTref_decfast  ,

["PRESS"] = VRI_KNOB_MODE_toggle  ,

["B SHOW"] = Rudder_Trim_show  ,

["B  +"] = Aileron_Trim_right  ,

["B ++"] = empty  ,

["B  -"] = Aileron_Trim_left  ,

["B --"] = empty  ,

}

 

The B group settings are not used on the Combo MCP Boeing or Airbus panels and are redundant. I believe these were implemented before the multiple modes were implemented. I need to know whether they are still used on the MCP1. It would also be useful to understand how they are used and switched. I am calling on those with a long memory to help me.

 

This feedback is important as I am in the process of removing these redundant legacy settings.
