When is the L/R FUEL LO warning triggered?

The L/R FUEL LO warning is designed to alert pilots when the fuel levels in the left or right wing tank drop to a critically low threshold. Specifically, the warning is triggered when there is approximately 110 pounds or less of usable fuel in either wing tank. This alert is crucial for flight safety as it prompts the pilot to monitor fuel consumption more closely and ensures that appropriate fuel management actions are taken.

Other potential conditions, such as a general fuel quantity being critically low, might not specify a precise weight limit, which would not meet the specificity of the L/R FUEL LO warning protocol. Similarly, while malfunctions or temperature issues in the fuel system are important operational considerations, they do not directly relate to the triggering of this specific low fuel warning. Thus, understanding the specific condition that triggers this alert is integral for safe flight operations and fuel management.
