Which is the smallest value among MTW, MTOW, MLW, and MZFW?

Explanation:
The smallest value is the maximum zero-fuel weight. MZFW is the limit for the aircraft’s weight with no usable fuel on board, meaning payload (cargo, passengers, crew, etc.) plus the basic empty weight must not exceed this value. Since fuel adds weight, the zero-fuel limit is typically lower than the limits for takeoff (MTW/MTOW) and landing (MLW). In the numbers given, MTW/MTOW are around 189,000–189,700 lbs, MLW is 149,800 lbs, and MZFW is 141,800 lbs. Therefore, 141,800 lbs is the smallest.
