|
|
What is used to prevent ice from forming on a propeller blade? |

|
|
Should an adjustable-pitch propeller be in high pitch or low pitch at takeoff? |
Low pitch |
|
|
What is done to cause a hydromatic propeller to feather? |
High-pressure Oil is directed into the propeller through the governor |
|
|
Does the centrifugal twisting moment on a propeller blade tend to move the blades toward high pitch or low pitch? |
Low pitch |
|
|
Do the counterweights on a propeller tend to move the blades toward high pitch or low pitch? |
High pitch |
|
|
What is the difference between a controllable propeller and constant-speed propeller? |
The propeller governor operates a constant-speed propeller and the controllable is manually operated |
|
|
When making a magneto check on an equipped with a constant-speed propeller, should the propeller control be in high pitch or low pitch position? |
Low-pitch position |
|
|
What can be done to prevent the front cone from bottoming when installing a propeller on a splined shaft? |
Install spacers behind the rear cone to move the propeller forward on the shaft |
|
|
What is the purpose of the small holes that are drilled in the end of a wooden propeller? |
For draining moisture that collects in the wood |
|
|
What is the function of the snap ring inside the hub of a propeller that is mounted on a tapered or splined shaft? |
For easy pulling off of the propeller from the shaft when the ring is backed off. |
|
|
What is adjusted inside the propeller governor for a constant-speed propeller to change the speed at which the propeller is operating. |
The compression of the speeder spring |
|
|
What is the function of the accumulator used on some McCauley feathering propellers? |
Stores oil under pressure during normal operations, and used to move the blades to low pitch to unfeather the propeller |
|
|
What is meant by beta range operation in a turboprop propeller? |
Mode of ground operation from starting, taxing and ground reverse |
|
|
What is meant by alpha range operation of a turboprop propeller? |
Inflight mode from takeoff to landing |
|
|
Is the flat surface of the propeller blade the face or the back of the blade? |
The face of the blade |
|
|
What keeps McCauley feathering propellers from feathering when the engine is shut down on the ground? |
A spring loaded latching mecahnism |
|
|
Where are most APUs located in a modern jet transport aircraft? |
On the tail cone of the fuselage |
|
|
What is the function of the APU? |
To supply electric power and compressed air when an airplane is on the ground and the engines are not operating |
|
|
What are two sources of compressor air from an APU? |
Compressor turbine and the load compressor driven by a free turbine in the engine |
|
|
Where in the maintenance information based on the ATA-100 System would you find instruction for inspecting the engine of an airborne APU? |
Section 49 20 |
|
|
How is most of the troubleshooting done for a modern APU? |
By the FADEC |
