What is the maximum zero fuel weight for the aircraft?

• A. 85,870 lb
• B. 85,517 lb
• C. 74,957 lb
• D. 69,886 lb

Answer: (D)

The concept being tested is maximum zero fuel weight. Zero fuel weight (ZFW) is the aircraft’s weight with all payload—passengers, baggage, cargo, and crew—but without any usable fuel. The maximum zero fuel weight (MZFW) is a fixed limit set by the airplane’s structure and balance. It defines how heavy the payload can be before fuel is added, ensuring the aircraft remains within structural and center-of-gravity limits when there is no fuel on board. When planning, you must not let payload push the ZFW above this limit; fuel is added later and increases takeoff weight, but does not affect the ZFW value itself. For the ERJ 175 in question, the specified maximum zero fuel weight is 69,886 lb. This is the highest payload-only weight the aircraft can carry while still staying within its design limits without fuel. The other numbers are higher than the MZFW and would violate this non-fueled weight limit if used, requiring payload reduction or a different configuration to stay compliant.
