What is meant by moment in the computation of weight and balance?
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.
What is meant by the tare weight that is used in a weight and balance computation?
The weight of the chocks and other items that are used to hold the aircraft on the scales.
What is meant by minimum fuel as is used in the computation of aircraft weight and balance?
No more fuel than the quantity necessary for one-half hour of operation at rated maximum continuous power. It is the maximum amount of fuel used in weight and balance computations when low fuel may adversely affect the most critical balance conditions.
Where is the arm of an item installed in an aircraft recorded?
In the Type Certificate Data Sheets for the aircraft.
What equipment must be installed in an aircraft when it is weighed to find its empty weight center of gravity?
All of the equipment that is listed in the Aircraft Equipment List as "required equipment" or as equipment that is permanently installed.
Why must we consider the category under which an aircraft is licensed when we compute its weight and balance?
The different categories under which an aircraft can be licensed have different maximum gross weights and different center of gravity ranges.
Which has the more critical center of gravity range, an airplane or a helicopter?
A helicopter.
Why are the distances of all of the items installed in an aircraft measured from the datum when computing weight and balance?
This makes it possible to find the point about which the aircraft would balance (the center of gravity).
What must be done to find the empty weight of an aircraft if it has been weighed with fuel in its tanks?
The weight of the fuel and its moment must be subtracted from the weight and moment of the aircraft as it was weighed.
What must be done to the tare weight when an aircraft is weighed?
It must be subtracted from the scale reading to find the weight of the aircraft.
