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 total weight of all passengers

Answer

The vertical distance between the wing and the fuselage

Answer

The maximum moment allowed by the aircraft manufacturer

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

Aircraft logbook only

Answer

Airworthiness Certificate

Answer

Aircraft registration only

Question 3

How is CG location calculated?

Accepted Answer

CG = Total Moment ÷ Total Weight

Answer

CG = Total Moment × Total Weight

Answer

CG = Total Weight ÷ Total Moment

Answer

CG = Total Weight × Total Arm

Question 4

What does a forward CG condition typically result in?

Accepted Answer

Increased longitudinal stability but reduced elevator effectiveness at low speeds

Answer

Decreased stall speed and improved stability

Answer

Reduced structural stress on the empennage

Answer

Improved maneuverability in all flight regimes

Question 5

What is 'zero fuel weight'?

Accepted Answer

The maximum allowable weight of the aircraft without usable fuel

Answer

The weight of the aircraft with all fuel tanks empty

Answer

The aircraft weight at the moment all fuel is consumed

Answer

The minimum weight for safe flight

Question 6

Which method of weighing an aircraft involves placing scales under each landing gear?

Accepted Answer

Platform scale method

Answer

Suspension method

Answer

Strain gauge method

Answer

Hydraulic weighing method

Question 7

When must an aircraft be leveled during an official weighing procedure?

Accepted Answer

Always — the aircraft must be in its level flight attitude to obtain accurate weight and balance data

Answer

Only when weighing helicopters

Answer

Only when the fuel tanks are full

Answer
