What documents provide information on how to level and weigh the aircraft?

For weight and balance calculations, how is the algebraic sign (+/-) of the 'arm' determined?

Under what circumstance will the algebraic sign of a weight be negative?

What two scenarios may cause a negative moment?

What does MAC stand for in aviation weight and balance.

How is the C of G of a transport category aircraft typically expressed?

What is the 'Mean Aerodynamic Chord (MAC)'?

In the context of wing design, what is the 'chord'?

The distance between the leading and trailing edge of the wing, measured parallel to the normal airflow over the wing, is known as:

What effect do tapered and swept wings have on chord length?

What is meant by 'Leading Edge of MAC (LEMAC)'?

What is the importance of the datum in aircraft weight and balance?

If an aircraft's new C of G is at station 914.6", after a modification, and the forward and aft C of G limits are at 860.2" and 1,040.9" respectively, is the new C of G within the allowable limits?

If an aircraft's new C of G is at station 883.7", following a modification, and the forward and aft C of G limits are at 860.2" and 1,040.9" respectively, is the new C of G within the allowable limits?

Why are repairs and modifications considered 'sources of weight change'?

What action is required following repairs and modifications that change the aircraft's weight?

What information must be recorded in the journey log after a modification affecting weight and balance?

According to standards, what document should be amended to reflect any change to installed equipment?

According to regulations, which of the following is required to be kept as a technical record for an aircraft?

What does a supplemental list contain within an aircraft having alternative configurations?

For an aircraft being operated in multiple different configurations, how are weight and balance changes documented.

According to standards, how should changes in an aircraft configuration be handled for weight and balance?

What is the consequence of ignoring the aircraft's weight and balance limitations?

Which of these actions requires a modification to the aircraft's weight and balance records?

Why is accurate weight and balance essential for flight safety?

What parameters are used to determine the center of gravity (CG) in weight and balance calculations?

What component of the aircraft can be used to level the aircraft?

What documentation is related to weight and balance that is required when a aircraft undergoes a modification?

What unit of measurement is used to determine the center of gravity?

Where is the Mean Aerodynamic Chord (MAC) located on an aircraft?

If a baggage item is moved from a location forward of the datum to a location aft of the datum, how will this affect the aircraft's center of gravity (C of G)?

An aircraft's weight is increased, but its C of G remains within the allowable limits. What is the likely consequence of this situation?

What is the relationship between 'arm' and 'moment' in weight and balance calculations?

An aircraft is loaded such that the combined moments of all items are within limits; however, the forward compartment is loaded to its maximum capacity while the aft compartment is nearly empty. What potential problem does this present?

The algebraic sign (positive or negative) of a weight used in weight and balance calculations is determined by what factor?

An aircraft's C of G is found to be outside the forward limit. What effect will this have on the aircraft's flight characteristics?

What is the primary reason for expressing the C of G of a large transport category aircraft as a percentage of the Mean Aerodynamic Chord (MAC)?

Following the installation of new avionics equipment in the nose of an aircraft, it is determined that temporary ballast is required. Where should this ballast ideally be placed?

An aircraft's initial weight and balance report indicates a specific equipment list. What action is required if a non-essential item from this list is temporarily removed for maintenance?

How does the presence of swept wings on an aircraft typically influence the calculation and management of its weight and balance, compared to an aircraft with straight wings?
