yes
Name the four engine modules
Cold section
Hot Section
Power Turbine Module
Accessory Section Module
the ATS serves what purpose?
ATS rotates the compressor, through the accessory section module until the engine compressor reaches self sustaining speed (52%ng)
what is the purpose of the radial driveshaft?
drives the accessory section
What is the purpose of the IPS?
separates foreign particles from inlet airflow and provides separation of foreign particles from the inlet airflow to protect the engine
Purpose of the Cold Section
Clean, Direct and compress air
Purpose of the Hot Section
mixing of air and fuel for combustion
Common Hydromechanical Unit
Pumps fuel
Meters fuel, pressurization and shutoff
NG Control
Variable stator vane actuation
Anti-icing

What does the engine fuel system provide to the engine?
automatic engine trim and load sharing between the engines to reduce pilot workload
Which occurs first, the red indicator button popping on the fuel filter housing, or the EUFD message FUEL 1 BYPASS?
the red indicator button pops first
The CHMU provides mechanical Ng overspeed protection to the engine at what percent Ng?
110+- 2%
The ODV receives an electrical Signal from the DECU/ECU when an Np overspeed exists, opening the overspeed solenoid valve, which stops fuel flow to the injectos. At what Np speed does this occur?
118.1 +-1%
The engine oil filter has an impending bypass indicator that will cause a red indicator to pop out when differential pressure across the filter reaches 40-60psid. Will this send a signal to the MP?
yes with a caution tone
What protects the engine lubrication system from excessive pressure during initial starts?
Cold Oil relief valve
The oil pressure transmitter is responsible for sending a low oil pressure signal to the MP. When the MP receives the signal what is the engine oil pressure?
20-25 psi
Does the C sump provide any emergency lubrication?
C sump does not provide emergency lubrication
How long is emergency oil lubrication provided when Ng is 75%?
30 seconds
Is the engine chip detector fuzz-burning or non-fuzz burning?
non fuzz burning
How is the engine anit-ice/start bleed valve mechanically controlled?
Controlled by the CHMU
once the engine is self-sustained during the start process, are the igniter plugs used any more prior to engine shutdown?
-----
Where does the thermocouple harness assembly measure the temperature of the gases for the engine?
Power Turbine inlet
In the event of an electrical system failure, what position will the anti-ice/start bleed valve be in?
fail safes in the opened position
How many volts AC does the engine driven alternator provide for the engine electrical system?
115 vac
When will the EDECU give you contingency power?
Np is less than 97%
Np is decelerating at 5% per second or greater
What Power lever quadrant requires electrical power to manipulate engine power levers?
ignition switch must be placed to batt or external power
When a power lever is advanced into lockout, what automatic features are lost?
Temperature limiting, overspeed protection
What is the ignition override switch used for?
Abort automatic start sequence or disengage ATS output shaft if the sprag clutch fails to disengage
What happens to both engines when the engine chop button is pressed?
immediately and simultaneously reduces both engines electronically to idle.
The MPD ENG page displays what three formats?
Ground
Flight
Emergency
What two status windows may appear in the upper right of the flight format when their associated systems are outside normal operating ranges?
Oil Pressure less than 23 or greater than 120

When the ENG page autopages to Emergency format in response to an active warning, how do you revert back to flight format?
selecting ACK button (B4)
What engine parameters utilize the count-down timer feature?
Torque, TGT, Ng
What are two types of engine hit checks that can be performed?
