Which statement about ballast is true?

• A. It powers the I2N
• B. It acts as a counterweight for FLIR and EOSS assembly
• C. It stores data
• D. It defines the radar's sector

Answer: (B)

Ballast is weight added to a system to keep it balanced and stable by controlling the center of gravity. In a setup that includes a FLIR and an EOSS sensor assembly, these components add significant weight at a particular location, which can shift the balance and affect stability and aiming. The ballast provides the counterweight needed to offset that extra load, helping keep the system level, reducing tilting or pitching, and enabling smoother operation of the gimbal and sensors. It improves stability and accuracy by ensuring the sensors stay properly oriented despite movement. The other statements describe functions ballast doesn’t perform—supplying power, storing data, or defining the radar’s sector—so they aren’t the correct description.
