The Maximum Structural Mass of your aircraft, according to the flight manual, is equal to 5300 lb for both take-off and landing, and can be increased by up to 50 lb for taxi. On a particularly hot and humid day, the Maximum All-up Mass has been reduced to 5100 lb. What is the regulated landing mass?

  • A

    5250 lb

  • B

    5150 lb

  • C

    5300 lb

  • D

    5100 lb

The Maximum Structural Landing Mass (5300 lb) is the maximum permissible total aeroplane mass upon landing under normal circumstances.

The Performance Limited Landing Mass (5100 lb) is the landing mass limited by similar destination airfield considerations,such as runway length, obstacles, temperature, altitude and humidity and derived from performance calculations.

The Regulated Landing Mass is the lower between the Performance Limited Landing Mass and the Maximum Structural Landing Mass: 5100 lb.

NOTE:

The taxi fuel is a fuel amount burnt before take-off and is irrelevant to the question.
