To assess aircraft performance, the pilot must..
  • A
    know the planned take-off, en-route and landing mass, and any subsequent changes from the load and trim documentation.
  • B
    know the mass of the aircraft at the previous landing and add the mass of the uplifted fuel.
  • C
    only use the certified mass information from the Aircraft Flight Manual.
  • D
    assess the actual zero fuel mass from the load and trim documentation and check that it does not exceed the certified limit.

The centre of gravity (CG) of an aircraft is the point over which the aircraft would balance.Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The centre of gravity affects the stability of the aircraft. To ensure the aircraft is safe to fly, the center of gravity must fall within specified limits established by the aircraft manufacturer.

Center of Gravity and Takeoff mass has to be calculated before each flight to make sure the aircraft within the safe envelope as exceeding limits in Takeoff, landing and during enrolee can end up with danger, lower performance and fatalities.

Correct Answer: Know the planned take-off , en-route and landing mass, and any subsequent changes from the load and trip documentation.
