Do low fuel warning lights provide accurate minimum fuel level indications during a fuel pump failure?

Low fuel warning lights are designed to alert pilots to a low fuel condition, however, they may not provide accurate minimum fuel level indications in the event of a fuel pump failure. When a fuel pump fails, the fuel system may not be able to draw fuel at the intended levels, leading to an incorrect reading of fuel quantity and possibly giving a false sense of security.

Additionally, the low fuel warning systems typically rely on various sensors and electrical connections to function properly. If the fuel pump is compromised, it can affect the overall accuracy of these systems because they may not be receiving the correct fuel level information. Consequently, pilots should not solely rely on the low fuel warning lights during fuel pump failures to assess their fuel status; other checks and procedures should be followed to ensure safety.
