An aircraft is loaded 110 pounds over maximum certificated gross weight. How much fuel should be drained to bring the weight within limits?

To determine how much fuel needs to be drained from the aircraft to bring its weight within the maximum certificated gross weight, it's essential to know the weight of the fuel. Aviation gasoline (Avgas) typically weighs about 6 pounds per gallon. Given that the aircraft is 110 pounds over the maximum weight, you can calculate the amount of fuel to drain by dividing the excess weight by the weight of fuel per gallon.

In this case, dividing 110 pounds by 6 pounds per gallon gives approximately 18.33 gallons. When rounding to a practical number for operational purposes, this rounds to 18.4 gallons. Therefore, to safely bring the aircraft back within weight limits, 18.4 gallons should be drained from the fuel tanks.

This answer aligns with the requirement to adhere to weight limits for safety and performance considerations, ensuring that the aircraft can safely operate within its designed parameters. Proper weight management is crucial in aviation, as it affects aircraft performance, handling, and safety.
