When air passes through the venturi of a carburetor, what three changes occur? velocity
increases, temperature decreases, and pressure decreases
carburetor icing may be eliminated by which of the following methods? alcohol spray and
heated induction air
which of the following is a function of the differential pressure controller? it controls all
positions of the waste gate except at fully open position.
A bent cooling fin on an aluminum cylinder head should be left alone if no crack has formed
some larger reciprocating engines use a compensating oil pressure relief valve to provide a
high engine oil pressure when the oil is cold and automatically lower the oil pressure when the
oil warms up
Repairs of aluminum alloy adjustable pitch propellers are not permitted to be made on which of
the following propeller blade areas? shank
the purpose of a relief valve installed in the tank venting system of a turbine engine oil tank is
to prevent oil pump cavitation by maintaining a constant pressure on the oil pump inlet

induction system at low RPM operation lean mixture

absorbs expansion
, which statement is correct regarding a continuous-flow fuel injection system used on many
recip engines fuel is injected at each cylinder intake port
Blade angle is an angle formed by a line perpendicular to the crankshaft and a line formed by
the chord of the blade
The compressor stators in a gas turbine engine act as diffusers to decrease the velocity of
the gas flow
Two continuous-loop fire detection systems that will not test due to a broken detector element
are the Kidde system and the Fenwal system
what is the primary purpose of the oil breather pressurization system that is used on turbine
engines? provides a proper oil spray pattern from the main bearing oil jets
a magneto ignition switch is connected parallel to the breaker points
the secondary coil of a magneto is grounded through the primary coil
which of the following best describes the blade movement of a full-feathering, constant speed
prop that is in the LOW RPM position when the feathering action is begun high pitch directly
to feather position
main bearing oil seals used with turbine engines are usually what type? labyrinth and/or
carbon rubbing
The function of the altitude compensating, or aneroid valve used with the Teledyne-Continental
fuel injection system on many turbocharged engines is to prevent an overly rich mixture
during sudden acceleration
