The fuel low level sensor lights the "L FUEL LO" and the "R FUEL LO" messages on the EICAS when the fuel level falls below 150 pounds in the respective tank.

The correct answer is that the statement is false. In the T-6B, the fuel low level sensor activates the "L FUEL LO" and "R FUEL LO" messages on the Engine Indication and Crew Alerting System (EICAS) when the fuel quantity in the respective tank drops below a specific threshold, which is typically set at a lower volume than 150 pounds. This threshold is critical for flight safety, as it allows pilots to receive timely alerts to manage fuel levels and make informed decisions regarding fuel management and potential landings.

Understanding the operational parameters of the fuel sensors, including the alert thresholds, is essential for effective aircraft operation and safety. By recognizing that the activation point for these warning lights is below 150 pounds, one appreciates the importance of maintaining awareness of fuel levels throughout the flight.
