Weigh Aircraft Flashcards
When should an aircraft be reweighed?
After an extensive repair or alteration that could change its weight or center of gravity.
Why is it necessary to consider the category under which an aircraft is licensed when computing its weight and balance?
Different categories under which an aircraft can be licensed have different maximum gross weights and different canter of gravity ranges.
Where do you find the leveling means that are specific for a particular aircraft?
In the Type Certificate Data Sheets for the aircraft.
What is meant by tare weight?
The weight of any chocks and other items that are used to hold the aircraft on the scales.
What must be done with tare weight when an aircraft is weighed.
It must be subtracted from the scale reading to find the weight of an aircraft.
Why are the distances of all 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)
Which has the more critical center of gravity range, an airplane or a helicopter?
A helicopter.
What is included in the empty weight of an aircraft?
The weight of the airframe, engines, and all items of operating equipment that have fixed locations and are permanently installed in the aircraft. Empty weight includes optional and special equipment, fixed ballast, full reservoirs of hydraulic fluid and engine lubricating oil, and unusable fuel.
Where is the maximum allowable gross weight of an aircraft found?
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 the equipment listed in the Aircraft Equipment List as “required equipment” or as equipment that is permanently installed.
What is meant by permanent ballast for an aircraft?
Weight that is permanently installed in an aircraft to bring the empty weight center of gravity into allowable limits.
Is there a Federal Gegulation requiring that all private aircraft be reweighed periodically?
No.
What must be done with temporary ballast when weighing an aircraft?
It must be removed from the aircraft.
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 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
