On the CAD display, which tanks are indicated as empty?

• A. Supply
• B. Main
• C. Both
• D. Left

Answer: (B)

Fuel level monitoring on the CAD display relies on sensor readings and visual indicators to show which tanks have content. An empty indication appears when a tank’s level is zero or below the low-threshold mark. In this scenario, the main tank shows empty, meaning its level sensor reads zero (or is in the empty state). The supply and left tanks still show content, so they are not empty. That’s why the main tank is the correct choice. If the display showed the supply or left tank as empty, those would be the ones indicated, but that isn’t the case here.
