Refer to figure.
The weight of an aircraft is 2 600 lb and the moment is 230 000 in·lb. Regarding the limits for weight and moment, complete the following statetment:

Weight is (1) _____ the limits and moment is (2) _____ the limits.

  • A
    (1) not within;
    (2) within.
  • B
    (1) within;
    (2) within.
  • C
    (1) not within;
    (2) not within.
  • D
    (1) within;
    (2) not within.

Refer to figure.
The intersection of the moment line and the weight line will correspond to the CG location:
(1) Weight: Draw a horizontal line from the right-hand side, from 2600 lb (blue line)
(2) Moment: Draw a diagobal line from the left-hand side, from 2300 (red line)

  • The maximum weight is 3650 lb => weight is within limits.
  • The intersection of the lines we have plotted are out of limits, which means that the CG is out of limits, exceeding the aft limit => moment is not within the limits.
