Which is not a source for determining a generator's fuel consumption rate?

• A. On-site fuel test data
• B. Manufacturer's manual or TO
• C. Local weather reports
• D. AF Form 487

Answer: (D)

Fuel consumption rate comes from data that quantify how much fuel the generator uses at a given output. On-site fuel test data provide real-world measurements of fuel used over a known period at a defined load, giving an actual consumption rate. The manufacturer’s manual or technical orders publish consumption figures or curves for various loads and conditions, which are the standard reference for expected fuel use. Local weather information can affect engine performance (ambient temperature, altitude, humidity, fuel density), so it’s useful for interpreting or adjusting consumption figures under different conditions, though it doesn’t itself supply a direct rate. AF Form 487, by contrast, is an administrative form and does not contain performance data about fuel consumption, so it isn’t a source for determining the rate.
