Weight And Balance

Question 1

Where must l a record be kept of the current empty weight and the current center of gravity of an aircraft?

Answer 1

In the aircraft flight manual or weight and balance records required by 14 CFR 23.1583

Question 2

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

Answer 2

A readily identified reference chosen by the aircraft manufacturer from which all longitudinal locations on the aircraft are referenced

Question 3

Why are the distances of all of the items installed in an aircraft measured from the datum when computing weight and balance?

Answer 3

This makes it possible to find the point about which the aircraft would balance (center of gravity)

Question 4

What are two reasons weight and balance control are important in an aircraft?

Answer 4

For safety of flight and for most efficient performance of the aircraft

Question 5

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

Answer 5

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 6

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

Answer 6

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

Question 7

What is meant by the arm of an item that is installed in an aircraft?

Answer 7

The distance, in inches, between the center of gravity of the item and the datum

Question 8

Why must we consider the category under which an aircraft is licensed when we compute it’s weight and balance?

Answer 8

The different categories under which an aircraft can be licensed have different maximum gross weights and different center of gravity ranges
