The oil pump assembly contains a pressure pump and ______ scavenge pumps. 5. 8. 10. 12.

The oil goes from the Engine Oil Surface Coolers (EOSC) or the surface cooler Bypass Valve (BPV) to the engine Fuel/Oil Heat Exchanger (FOHE) and then through the last-chance oil ______ to the bearing compartments and gearboxes. strainers. filters. screens. coolers.

Excitation power for the high pressure oil filter differential pressure transducer comes from channel A of the Engine Electronic Controller (EEC), while channel B of the EEC gives excitation power to the scavenge oil filter differential pressure transducer. Power for the Oil Debris Signal Conditioner (ODSC) and the Oil Debris Sensor (ODS) comes from channel A of the ______. HMU. MEDC. EEC.

The oil goes through the pressure oil filter to remove particle contamination, and this filter is monitored for ______. flow rate. temperature. pressure. differential pressure.

The scavenge air/oil mixture goes through the oil debris separator and the scavenge filter before it goes back to the ______. oil pump. oil tank. oil cooler. oil filter.

The core flow is used for combustion, driving the turbine sections, making some forward thrust, turbine cooling and sealing, Engine Section Stator (ESS) anti-icing, and High Pressure Compressor (HPC) servo air for valve control muscle pressure. The internal engine cooling and sealing gets air from IPC stage 8 - IP8, HPC stage 3 - HP3, and HPC stage 6 - ______. HP6. HP5. HP4. HP7.

A Secondary Air System (SAS) gets air from the compressor section. When selected, it uses this air to cool the engine (turbine) internally and seal and pressurize the main bearing ______. shaft. compartments. casings. chambers.

An airflow control system maintains stable airflow through the IPC and HPC over a wide range of speeds by changing the guide vane airflow angle of the IPC inlet air and opening compressor ______ valves at low speed and when airflow is disrupted. bypass. bleed. relief. exhaust.

The engine anti-icing system is designed to prevent any ice accretion that may occur, particularly in and around the areas of the ESS vanes at the inlet to the Intermediate Pressure Compressor (IPC), and the Variable Inlet Guide Vanes (VIGVs) that guide the airflow into the ______. ESS. IPC. HPC. fan.

Zone 1 is ventilated by ram air through an inlet in the inlet cowl and goes out through a vent that is combined with the right VFSG access door. Zone 2 fan air goes into the zone through inlets at the front edge of the core fairings and returns to the fan stream through outlets at the 3:00 and 9:00 positions near the A frame root. Zone 3 fan air goes into the zone through tubes on the thrust reverser inner wall and goes out between the aft edge of the thrust reverser inner wall and the ______. nacelle. exhaust sleeve. thrust reverser. fan stream.

The EEC sends start parameter data to the EICAS during the start sequence. True. False.

The EICAS Start mode indications include AUTORESTART. True. False.

The stable idle green tick mark disappears after the start sequence is complete. True. False.

AUTOSTART is displayed above the N2 display during the engine start sequence. True. False.

Monitoring oil pressure increase is unnecessary during the engine start sequence. True. False.

EGT increase and maximum should be monitored during the engine start sequence. True. False.

N1 and N3 increase should not be monitored during the engine start sequence. True. False.

The ignition system for each engine contains these components: Exciter box, High tension ignition lead, and ______. Ignition coil. Spark plug. Igniter plug. Starter motor.

Each ignition lead supplies the electrical output from the related ignition exciter to its ______. ignition coil. spark plug. igniter plug. starter motor.

The EEC sends a signal for a high-energy output voltage from the exciter when necessary. One of the two ignition systems operates at each ground start to prevent one plug from becoming more worn than the other and to ensure no ______. engine flooding. fuel leakage. system faults. performance issues.

The exhaust nozzle, forming the outer contour of the exhaust system, attaches to the outer flange of the Low Pressure Turbine (LPT), providing protection to the aft pylon with a ______. heat shield. fire seal. thermal barrier. insulation layer.

The forward and aft centerbody sections, part of the primary exhaust system, attach to each other and to the LPT case, forming the inner annulus of the exhaust system to streamline the gas flow from the LPT away from the engine, thus contributing to the generation of ______. reverse thrust. forward thrust. engine cooling. exhaust gases.
