Question 1
A work record headed “Fluid Flow, Pressure, and Temperature Indication” currently
contains “Propeller speed and shaft power readouts”. Which replacement entry would
best align the record with its stated focus?
A. Fuel pressure, fuel temperature, and fuel mass-flow metering systems (flow meters,
densitometers, totalizers)
B. Basic core components, air path, pressure/velocity changes, and pure reaction thrust
generation
C. Starting and Ignition Systems
D. Turboprop and turboshaft torque measurement principles (hydraulic torque meters, electronic
phase-shift torque meters, strain-gauge torque shafts)
Correct Answer: A
Full Explanation: “Fuel pressure, fuel temperature, and fuel mass-flow metering systems (flow
meters, densitometers, totalizers)” directly addresses “Fluid Flow, Pressure, and Temperature
Indication”. The existing entry, “Propeller speed and shaft power readouts”, is more directly
associated with “Torque and Power Indication Systems”. Replacing it with another unrelated entry
would not resolve the focus mismatch. The correction must restore the connection between the
heading and the work actually being described.
Question 2
Three work notes have been assigned focus labels. Note 1: “Thermocouple materials
(Chromel-Alumel, Iron-Constantan), measuring junctions, reference junctions, and
parallel/series harness configurations” → “Ignition Systems and Components”; Note 2:
“Manifold pressure indicators for auxiliary systems” → “Fluid Flow, Pressure, and
Temperature Indication”; Note 3: “Continuous ignition circuits (activation during
takeoff, landing, heavy precipitation, or turbulence)” → “Exhaust Gas Temperature
(EGT) and Interstage Turbine Temperature (ITT) measuring circuits”. Which single
correction restores all three relationships?
A. Leave all three focus labels unchanged
B. Exchange the focus labels of notes 2 and 3
C. Exchange the focus labels of notes 1 and 2
D. Exchange the focus labels of notes 1 and 3
Correct Answer: D
Full Explanation: The labels on notes 1 and 3 have been exchanged. “Exhaust Gas Temperature
(EGT) and Interstage Turbine Temperature (ITT) measuring circuits” includes “Thermocouple
materials (Chromel-Alumel, Iron-Constantan), measuring junctions, reference junctions, and
parallel/series harness configurations”; “Ignition Systems and Components” includes “Continuous
ignition circuits (activation during takeoff, landing, heavy precipitation, or turbulence)”. Exchanging
those two labels restores both connections and leaves the already-correct third note intact.
Swapping either with the third note would introduce a new error, while leaving the labels unchanged
preserves the two misclassifications.

Question 3
Several independent concerns have been raised. Case 1: “Data recording, trend
monitoring, and On-board Maintenance Systems (OMS) / Central Maintenance
Computers (CMC) interface”; Case 2: “Engine Pressure Ratio (EPR) computation and
instrumentation (ratio of turbine discharge total pressure to compressor inlet total
pressure)”; Case 3: “Modular construction design principles and major assembly
maintenance concepts”. Which ordered set of work areas matches the cases?
A. 1: Constructional Arrangement and Operation of Engine Types; 2: Vibration Monitoring and
Advanced Flight Deck Display Integration; 3: Thrust and Pressure Indication Systems
B. 1: Vibration Monitoring and Advanced Flight Deck Display Integration; 2: Thrust and Pressure
Indication Systems; 3: Constructional Arrangement and Operation of Engine Types
C. 1: Constructional Arrangement and Operation of Engine Types; 2: Thrust and Pressure
Indication Systems; 3: Vibration Monitoring and Advanced Flight Deck Display Integration
D. 1: Thrust and Pressure Indication Systems; 2: Vibration Monitoring and Advanced Flight Deck
Display Integration; 3: Constructional Arrangement and Operation of Engine Types
Correct Answer: B
Full Explanation: Case 1 fits “Vibration Monitoring and Advanced Flight Deck Display Integration”
because it concerns “Data recording, trend monitoring, and On-board Maintenance Systems (OMS) /
Central Maintenance Computers (CMC) interface”. Case 2 fits “Thrust and Pressure Indication
Systems” because it concerns “Engine Pressure Ratio (EPR) computation and instrumentation (ratio
of turbine discharge total pressure to compressor inlet total pressure)”. Case 3 fits “Constructional
Arrangement and Operation of Engine Types” because it concerns “Modular construction design
principles and major assembly maintenance concepts”. The correct answer preserves every
case-to-focus relationship. The other orders place at least one concern under a different focus; no
order of operations is being inferred.

Question 4
Two work areas need separate attention: “Exhaust Gas Temperature (EGT) and
Interstage Turbine Temperature (ITT) measuring circuits” and “High-Energy Ignition
(HEI) systems”. Which plan gives one directly relevant activity for the first area and
one for the second?
A. First: capacitors, discharge units (igniter boxes), high-tension leads, and surface-gap igniter
plugs; second: Thermocouple materials (Chromel-Alumel, Iron-Constantan), measuring junctions,
reference junctions, and parallel/series harness configurations
B. First: Oil pressure, temperature, and quantity monitoring circuits; second: capacitors, discharge
units (igniter boxes), high-tension leads, and surface-gap igniter plugs
C. First: Thermocouple materials (Chromel-Alumel, Iron-Constantan), measuring junctions,
reference junctions, and parallel/series harness configurations; second: capacitors, discharge units
(igniter boxes), high-tension leads, and surface-gap igniter plugs
D. First: Thermocouple materials (Chromel-Alumel, Iron-Constantan), measuring junctions,
reference junctions, and parallel/series harness configurations; second: Electric motor starters and
starter-generators
Correct Answer: C
Full Explanation: The first area is addressed by “Thermocouple materials (Chromel-Alumel,
Iron-Constantan), measuring junctions, reference junctions, and parallel/series harness
configurations”, while the second is addressed by “capacitors, discharge units (igniter boxes),
high-tension leads, and surface-gap igniter plugs”. The correct plan retains that distinction.
Reversing the activities assigns them to the wrong areas; replacing either activity with “Electric
motor starters and starter-generators” or “Oil pressure, temperature, and quantity monitoring
circuits” introduces a different focus and leaves one of the two stated work areas unaddressed.
Question 5
An entry about “Electric motor starters and starter-generators” was filed under “Fluid
Flow, Pressure, and Temperature Indication”. Which heading would provide the most
direct correction?
A. Thrust and Pressure Indication Systems
B. Turbojet Engines
C. Fluid Flow, Pressure, and Temperature Indication
D. Engine Starting Systems and Components
Correct Answer: D
Full Explanation: The entry describes “Electric motor starters and starter-generators”, an aspect
of “Engine Starting Systems and Components”. Moving the entry to that heading corrects its
classification without changing the work described. The original heading refers to “Fluid Flow,
Pressure, and Temperature Indication”; retaining it would leave the mismatch unresolved. The
remaining headings also fail to identify the entry's most direct focus.
