Engine Instrument System Flashcards
Many large high bypass turbine engine use what type of fuel control system
FADEC type
What are the units in the engine fuel flow system?
transmitter and a indicator
Where is the fuel flow transmitter located?
Mounted in the fuel line between the engine pump, and the carburetor
What type of readout is indicated on a fuel flow system?
Calibrate in record fuel flow in pounds per hour
What exactly does a mass fuel flow transmitter measured?
Density mass of the fuel that float through it
What is the reason for monitoring the fuel flow?
Fuel consumption and fuel flow indication is to see the engine is operating at the correct fuel air mixture for a given power setting
What does a manifold pressure gauge Indicate
Absolute pressure in the intake manifold
What will be the effect of a broken manifold, pressure gauge line
Cause the gauge to indicate atmospheric pressure
What does the engine tachometer indicate
Crankshaft rpm (engine, rpm)
What is the most likely cause of oscillating tachometer
A kink in the cable
What type of tachometer is used in multi engine aircraft
Alternating current tachometer generators
Why are turbine engines tachometer designed to indicate
Percent of engine shaft rpm(engine rpm)
What is the EPR on a turbine engine?
Ratio between turbine Discharge pressure to total inlet pressure.
What is the electrical source for a cylinder head temperature gauge?
Thermocouple attached to the cylinder head
Where is the carburetor air temperature bulb located?
In the air intake passage to the engine
