Data Pertinent to all Models

The location of the datum is specified and is described, for

example, as: 100 inches in front of the forward face of the

firewall bulkhead.

Manufacturer-Furnished Information

When an aircraft is initially certificated, its empty weight and

EWCG are determined and recorded in the weight and balance

record, such as the one in Figure 2-16. Notice in this figur

that the moment is expressed as “Moment (lb-in/1,000).” This

is a moment index, which means that the moment, a very

large number, has been divided by 1,000 to make it more

manageable. Chapter 4, Light Sport Aircraft—Weight and

Balance Control, discusses moment indices in more detail.

The aircraft is furnished with an equipment list, specifies

all the required equipment and all equipment approved for

installation in the aircraft. The weight and arm of all installed

equipment are included on the list and checked prior to the

aircraft leaving the factory.

When an aircraft mechanic or repairman adds or removes

any item on the equipment list, he or she must change the

weight and balance record to indicate the new empty weight

and EWCG, and the equipment list is revised to show

which equipment is actually installed. Figure 2-17 is from a

comprehensive equipment list that includes all of the items

of equipment approved for this particular model of aircraft.

The pilot’s operating handbook (POH) for each individual

aircraft includes an aircraft-s pecific equipment list of the

items from this master list. When any item is added to or

removed from the aircraft, its weight and arm are determined

in the equipment list and used to update the weight and

balance record. The POH and airplane flight manual (AFM)

also contain CG moment envelopes and loading graphs.

Examples of the use of these helpful graphs are given in

Chapter 5, Single-Engine Aircraft Weight and Balance

Computations.

In addition to the weight and balance report and equipment

list, the manufacturer also provides a CG range chart. The

CG range can be found in text form in the TCDS. The CG

range chart is furnished in the POH.
