Total fuel at full in pressure mode is what quantity?

• A. 19,594 LBS
• B. 14,580 LBS
• C. 7,492 LBS
• D. 4,610 LBS

Answer: (A)

Fuel quantity can be shown in different measurement modes. In pressure mode, the total fuel reading comes from pressure-sensing probes that sum the fuel in all tanks to a single total on the display. When the tanks are full, the total in pressure mode corresponds to the aircraft’s full-fuel capacity as read by that method. For the CRJ-550, the displayed total is 19,594 pounds, which matches the full-load reading you’d expect in pressure mode. This value reflects the system’s calibration for all tanks together, not just a single tank. If you were looking at gravity mode, you’d see a different number because that mode uses a different measurement method, but the question specifies pressure mode, so 19,594 pounds is the correct reading.
