What color does the fuel quantity tape on a side turn when it drops to 100 lbs?

• A. Red
• B. Green
• C. Yellow
• D. Blue

Answer: (C)

Color-coded fuel tapes provide a quick at-a-glance view of remaining fuel. As fuel is consumed, the tape shifts through color ranges: green for a comfortable level, yellow for a low-but-usable level, and red for critically low. When the level drops to about 100 pounds, the tape turns yellow, signaling the crew to begin fuel-management actions and consider diversion or landing as needed. This visual cue helps pilots maintain situational awareness even during high workload. The other colors reflect higher (green) or more urgent (red) fuel states, while blue isn’t used for this indication.
