CDC Vol 3
| Question | Answer |
|---|---|
| What could be a cause of a compressor stall when there is a reduction or restriction of air at the air inlet? | Icing of the aircraft or engine inlet |
| Which subsystem is not included in the oil system? | Monitoring |
| On the TF33 engine, where on the intermediate compressor case is the oil tank mounted? | Right |
| What type oil pump is on the TF33 engine? | Two section, single stage, gear driven |
| Which subsystem is not part of the oil indicating system? | Scavenge |
| What happens if the generator frequency becomes unstable? | Accuracy of electronic equipment is affected |
| A generator's voltage output is roughly proportional to its | revolutions per minute |
| How many electrical phases does a TF33 engine driven generator produce? | 3 |
| The generator control unit provides system protection and control, and | voltage regulation |
| during TF34 engine start, all fuel, up to a flow rate of how many pounds per inch, will pass the oil cooler? | 350 PPI |
| The TF34 fuel pump consists of a low and high pressure stage, relief valve, and a | Pressure regulating valve |
| How many pounds per square inch does the TF34 fuel pump boost stage increase the fuel inlet pressure? | 80 |
| When the red warning button is popper out on the fuel filter housing it indicates | fuel is bypassing the filter element |
| The splined coupling engine shaft transmits a signal of the core engine speed (the HPC and HPT speeds) to what fuel system component? | Main fuel control |
| Where is the excess metered fuel, from the servo and fuel pump discharge fuel, bypassed back to? | Inlet of the primary main pumping element |
| Metered fuel is supplied to the fuel distributor through the | quick engine change fuel flow transmitter and oil cooler |
| On engine shutdown, as fuel pressure decreases to below 40-60 pounds per square inch | opening the drain, shutting off fuel to the distributer |
| On the TF34-100A engine, injector 13 is configured differently to | provide clearance between the injector and fuel control |
| Under hot fuel conditions at the combustor inlet, the altitude starting capability of the TF34-100A engine | the diminished |
| During start up, all fuel flow up to how many pounds per hour, is forced through the bypass line around the oil cooler? | 350 |
| Which type of fuel system is used in the TF34-100A engine to prevent spontaneous combustion of residual fuel after engine shutdown? | Shut down drain system |
| The F108-CF-201 engine monitoring system data that is incorporated as part of the flight data recorder is used to determine | the need for maintenance before an engine failure occurs |
| Data that is recorded for each engine is downloaded and distributed via the | computer card |
| All of the options listed below are proper troubleshooting practices except | inspecting other areas after isolating trouble between points |
| In what format do technical orders present aircraft power plant and engine intermediate maintenance troubleshooting procedures? | troubleshooting charts |
| To become an expert troubleshooter, you must | understand the function of each component within each system |
| On an F108 engine, which manifold is the anti-ice air supplied from? | compressor case |
| On an F-108 engine, during which engine operation can the anti-ice valve be manually locked? | shutdown of idling |
| The inlet duct used on multiengine subsonic aircraft (like the C-5 or C-17) has a diameter that progressively | increases from the front to the back |
| The compressor bleed system reduces the probability of a compressor stall in a dual-rotor engine by | reducing the amount of air available to the HPC |
| What stage of the compressor airflow provides the cooling air for the turbine nozzle vanes? | last |
| On an F108-CF-100 engine, the direction of the variable bleed valve rotation is controlled by the | compressor |
| On an F108-CF-100 engine, which cable relays the variable bleed valve position to the main engine control as the valve approaches the commanded closed position | Feedback |
| One type of aerodynamic blockage thrust reverser uses | vanes inside the duct to create swirling gases |
| How many core blocker doors are on the F117-PW-100 engine? | 7 |
| The function of the fuel pump on an F117 is to provide fuel directly to the fuel | control |
| What two components operate together to provide the thrust management system for the F117? | electronic engine control and fuel control unit |
| A typical het engine exhaust gas temperature indicating system contains thermocouples, thermocouple leads, an indicator, and a | resistor |
| What fuel-flow system component of a jet engine operates by using a water wheel concept? | transmitter |
| Two units that work together to indicate the oil system is operating correctly is the oil pressure | transmitter and indicator |
| An oil pressure transmitter contains a mechanical section and a | synchronous unit |
| Where is the tachometer driver located that operates the high compressor rotor tachometer generator? | engine accessory section |
| What switch is pushed during an operational check of the fire warning system? | TEST |
| The test cell EGT selector allows selection of | individual thermocouple inputs of an average of these inputs |
| Within how many RPMs is the accuracy of the test cell low and high pressure compressor speed indicators | 2 |
| What type of vibration causes unnecessary engine removals and unwarranted repairs? | externally excited |
| During vibration analysis, frequency is usually measured in | cycles per second |
| Which type of vibration transducer is made up of certain ceramic compounds and natural crystals? | Piezoelectric accelerometer |
| The filter selector switch on the vibration analyzer | allows selection of the necessary filter to remove the natural vibration frequencies of a specific engine |
| What supports the fan and LPT of a jet engine? | bearings |
