Perform Weight-and-balance Check and Record Data.

Question 1

What are two reasons weight and balance control are important?

Answer 1

For safety of flight and for most efficient operation of the aircraft.

Question 2

Where is the center of gravity for most airplanes located in relation to the center of lift?

Answer 2

The CG is normally ahead of the center of lift.

Question 3

What is meant by the datum that is used for weight and balance computations?

Answer 3

It is a readily identified reference chosen by the aircraft manufacturer from which all longitudinal locations on the aircraft are referenced.

Question 4

What is meant by moment in the computation of weight and balance?

Answer 4

A force that tends to cause rotation. It is the product of the weight of an object in pounds and the distance of the object from the datum in inches.

Question 5

How do you find the moment of an item installed in an aircraft?

Answer 5

Multiply the weight of an item in pounds by its distance from the datum in inches.
