|
When should an aircraft be re-weighed? |
After an extensive repair or Alteration that could change its weight Or center of gravity. |
|
|
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 an aircraft.Empty weight includes optional and special equipment, fixed ballast, Full reservoirs of hydraulic fluid , engine lubricating oil, and unusable fuel |
|
|
What equipment must be installed in an aircraft when it is weighed to find it’s empty weight center of gravity? |
All 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. |
|
|
What is meant by minimum fuel as is used in the computation of aircraft away and balance? |
No more fuel than the quantity necessary for 1/2 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. |
|
|
What is meant by the maximum zero fuel weight of an aircraft? |
The maximum permissible weight of a loaded aircraft . passengers, crew, cargo |
|
|
What is meant by permanent ballast for an aircraft? |
Weight that is permanently installed an aircraft to bring the empty weight center of gravity into allowable limits. |
|
|
What is meant by the arm of an item installed in an aircraft? |
The distance, in inches, between the center of gravity of the item and the datum. |
|
|
What is meant by a moment index? |
A moment divided by a constant such as 10 100 or 1000. |
|
|
What is meant by the center of gravity range? |
The distance in inches between the forward allowable center of gravity and the rearward allowable center of gravity. |
|
|
What is the significance of the empty weight center of gravity range of an aircraft? |
If the empty weight center of gravity falls within the empty weight center of gravity range, the aircraft cannot be legally loaded in such a way that it’s loaded center of gravity will fall outside of the allowable loaded center of gravity range. Not all aircraft have an empty weight center of gravity range. |
|
|
Why is the empty weight center of gravity range not given in the type certificate data sheet for some aircraft? |
The empty weight center of gravity range is given only for aircraft that cannot be legally loaded in such a way that their loaded center of gravity will fall outside of the allowable limits. |
|
|
What is meant by mean aerodynamic chord? |
The chord of an imaginary airfoil that has the same aerodynamic characteristics as the actual airfoil. |
|
|
What is a loading envelope? |
The enclosed area on a graph of an airplane’s loaded weight and CG location.If lines drawn from the weight and CG cross within this envelope the airplane is properly loaded. |
|
|
Where must a record be kept of the current empty weight and the current center of gravity of an aircraft? |
In the aircraft flight manual or weight and balance records. |
