What are the components in the fuel injection system? correct answers The electrically driven
auxiliary fuel pump, which delivers provides fuel pressure if the engine-driven pump fails;
the fuel manifold valve, which distributes fuel evenly to all cylinders and provides a fuel
shutoff
What is a correct statement regarding the indications that occur on the tachometer and
manifold pressure gauges with changes in throttle and propeller control positions? correct
answers With the throttle at takeoff power, if you move the propeller control from full
forward to cruise r.p.m., high manifold pressure could cause engine limits to be exceeded.
What is true regarding a full authority digital engine control system? correct answers You use
a single lever to set the power instead of managing separate control for throttle, mixture, ad
propeller.
As an airplane with a turbocharging system climbs with a set manifold pressure, how does the
system operate? correct answers A pressure control mechanism senses changes in compressor
discharge pressure and gradually closes the waste gate to increase the flow of exhaust gases
through the turbine.
what are the primary components of the turbocharging system? correct answers Compressor
section that houses the impeller used to accelerate induction air; turbine section that houses
the turbine wheel driven by exhaust gases; waste gate to vary the mass of exhaust gas flowing
into the turbine.
What blade angle (pitch) should you select on a constant-speed propeller for the most
efficient performance? correct answers During takeoff and climb, select a low blade angle
(pitch) to generate high r.p.m. for maximum thrust, decreased takeoff distance, and improved
climb performance.
What is true about the cylinder head temperature (CHT) gauge? correct answers The CHT
display is marked with colored range markings and numerical temperature valves that denote
the engine's normal and extreme temperature parameters.
What is true regarding the exhaust has temperature gauge? correct answers The best power
mixture produces the greatest amount of power for a given setting and is set by enriching the
mixture to produce a cooler EGT reading, ranging from 25DF to 125DF on the rich side of
peak
What actions should you take to effectively operate a turbocharged engine? correct answers
Allow the turbocharger to cool and the turbine to slow its rotation before shutting down the
engine to prevent carbon deposits from forming on the bearings and shaft, which decreases
the turbocharger's efficiency and service life.
The microswitches on the landing gear, control which of the following cockpit indications?
correct answers Green landing gear lights
What arms the landing gear warning horns? correct answers The landing gear lever
microswitch.
, What is the purpose of the squat switch? correct answers It prevents you from inadvertently
retracting the gear on the ground.
Why do most manufacturers put a detent in the landing gear lever? correct answers To
prevent inadvertently retracting the gear on the ground.
What is Vlo? correct answers The maximum landing gear operation speed that the gear can
be safely extended or retracted.
What component of the hydraulic landing gear system sequences the main and nose landing
gear? correct answers Restrictor valve
Without the aid of up locks, the loss of hydraulic pressure while the landing gear is in the up
position, results in which of the following? correct answers The landing gear falls with
gravity to the down position.
What turns the electrically driven hydraulic pump on? correct answers The landing gear
lever.
In an airplane with an electrical landing gear system, the loss of electrical power while the
landing gear is in the up position, results in which of the following? correct answers The
landing gear remains in the up position.
What is Vle? correct answers The maximum landing gear extension speed that the aircraft
can be flown with the landing gear extended in the down and locked position.
In an airplane with a hydraulic landing gear system, how is the landing gear held in the up
position? correct answers Hydraulic pressure
In an airplane with an electrical landing gear system, what turns the landing gear electric
motor on? correct answers The landing gear lever
Without the aid of up locks, when does the electrically driven hydraulic pump run with the
landing gear in the up position? correct answers The pump intermittently runs to maintain the
required hydraulic pressure to keep the landing gear in the up position.
What is the purpose of the hydraulic pressure switch? correct answers It turns the electric
pump off when the landing gear reaches the full up position.
In an airplane with an electrical landing gear system, the loss of electricity while the landing
gear is in the down and locked position, results in which of the following? correct answers
The landing gear remains down and locked.
In an aircraft with an electrical landing gear system, what holds the landing gear in the up
position? correct answers Mechanical linkage
In a cabin pressurization system, what is the function of the outflow valve? correct answers
Regulates and maintains cabin pressure by allowing air to escape from the cabin.
