What must each fuel quantity indicator be calibrated to read during level flight when the quantity of fuel remaining is equal to the unusable fuel supply?

  1. Zero

  2. Full

  3. Half

  4. Quarter

The correct answer is: Zero

During level flight, all fuel quantity indicators must be calibrated to read zero when the quantity of remaining fuel is equal to the unusable fuel supply. This is because the unusable fuel supply cannot be safely utilized in the aircraft and does not have an impact on the available fuel for use. The other options, such as B Full, C: Half, and D: Quarter, do not accurately reflect the true amount of fuel remaining and could lead to incorrect fuel usage calculations and potential fuel shortages.
