Engine instrument systems Flashcards
What are the units in an engine fuel flow system
The system consists of a transmitter and an indicator for each engine
Where is the fuel flow transmitter located
It is mounted in the fuel line between the engine driven pump and the carburetor
What type of readout is indicated on a fuel flow system
The indicator is calibrated to record the fuel flow in pounds per hour
What exactly does a mass fuel flow transmitter measure
The density mass of the fuel that flows through it
What is the reason for monitoring the fuel flow
In addition to the fuel consumption, the operator can determine from the fuel flow indicator where are the engine is operating at the correct feel air mixture for a given power setting
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
Will cause the gauge to indicate atmospheric pressure
What does the engine tachometer indicate
Crankshaft speed rpm
What is most likely to cause an oscillating tachometer
A kink in the cable
What type of tachometer is used in multi engine airplanes
Alternating current tachometer generators
What are turbine engine taco meters designed to indicate
They are designed to indicate percent of engine rotor RPMs
What is the EPR on a turbine engine
The ratio between total turbine discharge pressure to total inlet pressure, and is indication of the thrust being developed by the engine
What is the electric source for a cylinder head temperature gage
A thermal couple attached to the cylinder head
Where is the carburetor air temperature bulb located
Located in the air intake passage to the engine
How can turbine engine EGT be checked with our operating the engine
By checking resistance to the thermal couples and circuits
