|
What is the purpose of weight and balance control? |
Primary: Safety Secondary: Efficiency |
|
|
What is the datum, and what is its function? |
Imaginary vertical plane from which all longitudinal measurements are taken |
|
|
What is tare weight, and how is it handled when performing weight and balance control? |
Weight that is not a part of the airplane that is subtracted from the scale reading |
|
|
What is meant by residual fuel? |
The fuel that is left in the tank, lines and components when the aircraft is placed in level flight position and the fuel drained at the main fuel strainer. This is also called residual fuel. |
|
|
How is the moment of an item of equipment obtained when computing aircraft weight and balance? |
The weight of the object multiplied by the distance from the datum |
|
|
How is the arm of an item obtained when computing aircraft weight and balance? |
Measured from the datum, in inches |
|
|
How could you correct an aircraft that has exceeded its forward CG limit after several items of equipment have been installed in the engine compartment without removing those newly added items. |
Add weight aft of the CG |
|
|
Name an undesirable flight characteristic that is most likely to result from exceeding the forward CG limit of an aircraft |
Nose heavy condition |
|
|
What is ballast and why is it used in aircraft? |
Weight to bring the airplane back to a desired CG range |
|
|
What should be done concerning fuel when weighing an aircraft for weight and balance purposes? |
The weight of the fuel & its moment must be subtracted from the weight & moment of the aircraft as it was weighed. |
|
|
How could you determine the empty weight and empty weight CG of an aircraft if all the weight and balance records are missing? |
The aircraft is weighed, & the empty weight center of gravity is computed. These values are recorded in new weight and balance records that are started for the aircraft. |
|
|
How is a positive moment obtained aft of the datum? |
Adding weight |
|
|
How is a negative moment obtained forward of the datum? |
Adding weight |
|
|
What is meant by the term residual oil? |
Oil trapped in lines, filters, etc. |
|
|
What is the difference between fixed wing and helicopter CG ranges? |
More restricted for Helicopters |
|
|
Where would you find the leveling means for a particular aircraft? |
Type Certificate Data Sheet (TCDS) |
|
|
What does the "mean aerodynamic chord" (MAC) refer to? |
Average length of the chord of a wing |
|
|
What are two ways commonly used to express weight and balance data for different aircraft? |
A loading schedule or weight and balance envelope (chart) |
|
|
What is an aircraft loading graph? |
A rapid method for determining CG location for loading |
|
|
What should be done with equipment carried in an aircraft but not permanently installed in the aircraft when weighing an aircraft? |
Equipment if it's MEL, should be weighed with the aircraft, if not-should be subtracted from scale readings. |
