AM Aircraft Weight & Balance 2

Question 1

What is the 'arm' in weight and balance terminology?

Accepted Answer

The horizontal distance from the datum to the point where weight acts

Answer

The arm is the horizontal distance measured in inches from the datum to the point where a weight is applied or acts.

Question 2

After making a major repair or alteration that affects weight and balance, what must be updated?

Accepted Answer

Weight and Balance Report and equipment list

Answer

Any major repair or alteration affecting weight and balance requires an updated Weight and Balance Report and equipment list to reflect current empty weight and CG.

Question 3

How is CG location calculated?

Accepted Answer

CG = Total Moment ÷ Total Weight

Answer

CG location is found by dividing the total moment (sum of all moments) by the total weight, giving the CG in inches from the datum.

Question 4

What does a forward CG condition typically result in?

Accepted Answer

Increased longitudinal stability but reduced elevator effectiveness at low speeds

Answer

A forward CG increases longitudinal stability but may reduce elevator effectiveness, requiring higher approach speeds and greater back pressure.

Question 5

What is 'zero fuel weight'?

Accepted Answer

The maximum allowable weight of the aircraft without usable fuel

Answer

Zero fuel weight is the maximum certificated weight of the aircraft and its contents, excluding usable fuel, used to limit structural bending loads on the wing.
