At what fuel weight does the FUEL LOW caution message illuminate?

• A. 22 pounds
• B. 63 pounds
• C. 100 pounds
• D. 198 pounds

Answer: (C)

The FUEL LOW caution message illuminates at 100 pounds of fuel weight. This threshold is set to alert the flight crew when the fuel level has dropped to a critical level, indicating that there is a limited amount of fuel remaining to complete the flight safely. By setting this limit at 100 pounds, the aircraft systems ensure that pilots are aware of the low fuel situation, allowing them to take appropriate action if necessary, such as preparing for a landing or rerouting to a nearby refueling station. This safety feature is crucial for maintaining operational awareness and ensuring the safety of the flight. The other options represent fuel weights that are either too low or well above typical fuel reserves for safe flying, which would not trigger the caution message.
