In the mixing assembly, which statement is true about the first stage mixing?

• A. Top of the ILCA; Combines two axes into one
• B. Bottom of the ILCA; Combines two axes into one
• C. Top of the ILCA; Splits into two axes
• D. Inside the cockpit; Combines two axes into one

Answer: (A)

In a mixing system, the first stage is all about blending two separate input commands into one resulting signal. This merged signal represents a coordinated input that other stages can then shape or distribute. Placing this first-stage mixer at the top of the ILCA makes sense because that’s where the input linkages come together first, producing a single output before any subsequent processing. If mixing happened at the bottom or inside the cockpit, or if the stage split the inputs into two outputs, it would not be forming that single initial command. So, combining two axes into one at the top of the ILCA is the correct description.
