Which statement about CRJ-700 weights is true?

Which statement about CRJ-700 weights is true?

• A. The Maximum Landing Weight is greater than the Minimum Operating Empty Weight.
• B. The Normal Rated Thrust is greater than APR Thrust.
• C. The APU Battery has a lower voltage than the Normal Battery.
• D. Bleed air start pressure is 50 psi.

Answer: (A)

The weights tested here relate to how heavy an airplane is allowed to be in different phases of flight. The minimum operating empty weight is the lightest weight at which the aircraft can operate—this includes the airframe, mandatory equipment, crew, and essential fluids. The maximum landing weight, on the other hand, is the upper limit on how heavy the airplane is permitted to be when it touches down, to ensure safe landing performance. Logically, the airplane must be able to carry payload and fuel to perform its mission, which means you’ll often be operating heavier than the bare empty weight. Therefore, the landing weight limit must be greater than the lightweight, baseline operating weight. In other words, there’s a range of acceptable landing weights that starts above the minimum operating empty weight and goes up to the maximum landing weight, making the statement that the maximum landing weight is greater than the minimum operating empty weight true. The other statements refer to thrust ratings, battery voltages, and bleed air start pressures, topics that are unrelated to the weight relationship above.
