Multiple Choice

In the context of the 737 fuel system, which parameter indicates an imbalance that the crew must monitor?

Fuel distribution across tanks is tracked because asymmetric fuel affects aircraft balance and control. The 737 uses multiple tanks, and the crew monitors the difference in fuel quantity between them. When the tank imbalance exceeds limits, they take action to re-balance the load, typically by using the crossfeed and transfers to even out the remaining fuel. This keeps the center of gravity within safe envelopes and ensures symmetrical thrust availability if an engine issue arises. The other options don’t relate to fuel balance: oil temperature is an engine lubrication parameter, cabin altitude concerns pressurization, and flight level refers to altitude.
