1. What constitutes a capacitor? |
Two conductors separated by an insulator. |
|
|
2. What is the purpose of a capacitor? |
It stores electrical energy in electro static in electrostatic fields. Doe |
|
|
3. Does a capacitor in an AC circuit cause the current to lead or lag the voltage? |
It causes the current to lead the voltage. |
|
|
4. What is the basic unit of capacitance? |
The Farad |
|
|
5. Why should electrolytic capacitors not be used in an AC circuit? |
They are polarized. An electrolytic capacitor will pass current of one polarity, but will block current of the opposite polarity. Wha |
|
|
What is meant by inductance? |
The ability to store electrical energy in electromagnetic fields. |
|
|
What is the basic unit of inductance. |
The Henry |
|
|
What is an example of an inductor used in a magneto? |
The coil. |
|
|
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 weight and different center of gravity ranges |
|
|
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 center of gravity ranges. |
|
|
What must be done with tear weight when an aircraft is Wade |
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 scale. |
|
|
What must be done with tare weight when an aircraft is weighed. ? |
It must be subtracted from the scale readings to find the weight of the 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 a point about which the aircraft would balance (the center of gravity) |
|
|
Which has the more critical center gravity range, and airplane or a helicopter? |
A helicopter |
|
|
What is included in the empty weight of an aircraft? |
The weight of an air frame, 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 oil engine lubrication oil, and unusable fuel |
|
|
Where is the maximum allowable gross weight of an aircraft found? |
The type certificate data sheets for the aircraft |
|
|
What equipment must be installed in an aircraft when it is weighed to find it's empty weight center of gravity? |
All the equipment listed in the Aircraft Equipment List as "required equipment" or as equipment that is permanently installed. |
