Advanced MFD
From EECH Central
Alternative MFD symbology
If "advanced_mfd" value is "1" alternative MFD layout will be used (if available). For EECH 1.15.2 it's EO screens for Ka-52, Ka-50 and Mi-28. With "advanced_mfd = 0" default layouts will be used.
Be sure, that "colourmfd" value is "1", otherwise default layouts will be used whatever "advanced_mfd" value is.
