When does the L/R FUEL FEED annunciator illuminate?

When does the L/R FUEL FEED annunciator illuminate?

• A. When the fuel feed chamber drops below 70 lbs (11 gal)
• B. When the fuel temperature sensor is activated
• C. When the fuel feed chamber is overfilled
• D. When there is a blockage in the fuel line

Answer: (A)

The L/R FUEL FEED annunciator illuminates when the fuel feed chamber drops below 70 lbs (11 gal). This indicator serves as a critical alert to the pilot, signaling that the fuel level in the feed chamber has become low enough to potentially impact engine performance. Maintaining fuel within an adequate range is essential for ensuring the engine operates reliably and efficiently. If the fuel level falls below this threshold, it can increase the risk of fuel starvation, especially during high-demand phases of flight. By activating under this condition, the annunciator prompts the pilot to take necessary actions, such as monitoring fuel consumption or preparing for a fuel management strategy. Thus, understanding this function is vital for safe flight operations.
