Question: 1 / 1030

When fuel quantity is measured in pounds instead of gallons, the measurement will be

more accurate because fuel volume varies with temperature change

When fuel quantity is measured in pounds instead of gallons, the measurement will be more accurate because fuel volume varies with temperature change. In aviation, fuel weight is more critical than volume as weight directly affects the performance and balance of the aircraft. Since the density of fuel can change with temperature variations, measuring in pounds accounts for these changes, providing a more accurate representation of the actual amount of usable fuel on board. Solid fuels would not typically be used for aircraft propulsion, making option D incorrect. Option B is misleading as it does not accurately portray the reason why measuring in pounds is more accurate. Option C is also incorrect because, as stated earlier, fuel weight and volume can change with temperature variations.
