What does the Center of Gravity (CG) Control do?

• A. The signal data computer monitors the amount of fuel in tanks #1 and #4; If fuel in tank #4 becomes excessive the computer will close the valves in the effected tank to prevent a CG problem.
• B. It heats fuel before entering engines.
• C. It monitors fuel quantity in all tanks and dumps excess.
• D. It controls refueling rate.

Answer: (A)

Center of Gravity control keeps the airplane balanced by actively managing how fuel is distributed between tanks. It uses a dedicated computer to watch fuel levels in selected tanks and then adjust valve states to keep the overall center of gravity within safe limits.

In the Growler, the CG control monitors tanks 1 and 4. If tank 4 becomes excessive, the system automatically closes the valves in that tank to prevent the CG from drifting outside acceptable bounds, maintaining proper balance and controllability.

Heating fuel, dumping excess, or dialing in refueling rate are related to other systems (fuel conditioning, fuel dump, and refueling operations, respectively) and do not describe the CG balancing action.
