Engine Instruments Flashcards
Who is authorized to repair a fuel flow indicating system
only by an FAA approved repair station certificated for a certain instrument
Where can you find the electrical power requirements for a fuel flow indicating system
Aircraft maintenance manual
What type of instrument system is used for measuring cylinder head temperature and exhaust gas temperature
Thermocouple system
What should a thermocouple cylinder head temperature indicator read when the engine is cold
Same as the outside temperature
What should a ratiometer temperature indicator read when electrical power is off
Pointer should be off scale on the low side
What are the units in engine fuel flow system
A transmitter and indicator for each engine
What does a manifold pressure gauge indicate
Absolute pressure in the intake manifold
What would be the effect of a broken manifold pressure gauge line
Gauge will indicate atmospheric pressure
What does the engine tachometer indicate
Crankshaft speed RPM
What is the electric source for a cylinder head temperature gauge
Thermocouple attached to cylinder head
Where is a carburetor air temperature bulb located
In the air intake passage to the engine
What kind of indicator mechanism is used to measure oil pressure
Bourdon tube
What kind of indicator mechanism is used to measure manifold pressure
Differential bellows
What is used to fill the line between a fuel pressure gauge and the fuel metering system
Light oil such as kerosine
What is the range of pressure needed for a fuel pressure gage used with float carburetor
Normally between 1 to 25 psi
