Which data point is calculated by the FSC to help manage fuel balance?

• A. Fuel quantity of each tank
• B. Pilot weight
• C. Outside air humidity
• D. Vertical speed

Answer: (A)

Balancing fuel relies on knowing exactly how much fuel sits in each tank. The FSC is designed to monitor the aircraft’s fuel distribution, using tank sensors to estimate the amount of fuel in each tank and then present those per-tank quantities (often along with the total fuel). This per-tank data is what you use to judge whether an imbalance exists and to decide if transfers or crossfeed are needed to even things out. Other factors listed don’t directly reflect where the fuel sits in the wings or fuselage. Pilot weight affects overall weight and center of gravity but isn’t a per-tank fuel quantity the FSC calculates. Outside air humidity and vertical speed don’t inform you about how fuel is distributed across tanks, so they aren’t the data point used to manage fuel balance.
