What is a megawatt?
|
one million (1,000,000) Watts
|
|
What is meant by reactive power in an AC circuit?
|
The power consumed in the inductive and capacitive reactances in an AC circuit. Reactive power is also called wattless power.
|
|
In what units is reactive power expressed?
|
In volt-amps reactive (VAR), or kilovolt- amps reactive (KVAR).
|
|
What is meant by power factor in an AC circuit?
|
The ratio of true power to apparent power. It is also the ratio of circuit resistance to circuit impedance.
|
|
Why is the closed-circuit voltage of a lead acid battery lower than its open circuit voltage?
|
Voltage is dropped across the internal resistance of the battery.
|
|
What is a detail drawing?
|
A drawing that includes all the information needed to fabricate the part.
|
|
What is a block diagram?
|
A drawing that shows various functions of a system by a series of blocks. These blocks do not include any detail, but indicate what happens in each block.
|
|
What is the purpose of a sketch of a repair?
|
It shows a specific bit of information and includes the minimum amount of detail needed to manufacture the part.
|
|
What are four steps in making a sketch?
|
Block in the the space and basic shape

|
What is included in the empty weight of an aircraft?
|
The airframe, engines, permanently installed operating equipment, optional &special equipment, fixed ballast, hydraulic fluid, engine oil, and unusable fuel.
|
|
Where is the maximum allowable gross weight of an aircraft found?
|
TCDS
Type Certificate Data Sheet |
|
Where do you find the arm of an item installed in an aircraft?
|
TCDS
Type Certificate Data Sheet |
|
What is meant by moment index?
|
A moment divided by a constant such as 10, 100, or 1,000
|
|
What is the significance of the empty weight center of gravity range of an aircraft?
|
If the empty weight CG falls within the EWCG range, the aircraft cannot be legally loaded in a way that its CG will fall outside of the allowable loaded CG range. Not all aircraft have a EWCG.
|
|
What is meant by the Mean Aerodynamic Chord (MAC)?
|
The chord of an imaginary airfoil that has the same aerodynamic characteristics as the actual airfoil.
|
