This level of understanding is essential for becoming an expert troubleshooter and successfully resolving complex technical issues.

The tachometer indicating system consists of two primary units: the tachometer generator and the tachometer indicator. The tachometer generator is responsible for generating electrical signals based on the rotational speed of the engine. These signals are then sent to the tachometer indicator, which is the device that displays the engine's rotational speed in revolutions per minute (RPM). Therefore, the correct answer is "indicator" as it is an essential component of the tachometer indicating system.

Most engine monitoring gauges and instruments require a transmitter and indicator. The transmitter collects data from various sensors and converts it into electrical signals. These signals are then transmitted to the indicator, which displays the information to the operator. This setup allows for real-time monitoring of engine parameters such as temperature, pressure, and fuel level. By using a transmitter and indicator, accurate and reliable readings can be obtained, ensuring the safe and efficient operation of the engine.

The correct answer is troubleshooting charts. Aircraft power plant and engine intermediate technical orders (TO) provide information on troubleshooting, which is presented in the form of troubleshooting charts. These charts help technicians identify and resolve issues with the power plant and engine by providing step-by-step instructions and diagnostic flowcharts. They are a valuable resource for maintenance personnel to efficiently troubleshoot and rectify problems in the aircraft's power plant and engine systems.

The oil pressure transmitter and indicator are two units that work together to indicate that the oil system is operating correctly. The oil pressure transmitter measures the pressure of the oil and sends the information to the indicator, which displays the pressure reading. This allows operators to monitor the oil pressure and ensure that it is within the desired range. If there is any issue with the oil system, such as low pressure or a blockage, it will be reflected in the readings on the indicator. Therefore, the transmitter and indicator are crucial in determining the proper functioning of the oil system.

The engine fuel-flow indicating system of most jet powered aircraft contains a transmitter and a fuel flow indicator. This system is responsible for measuring and displaying the rate at which fuel is flowing into the engine. The transmitter is used to convert the fuel flow data into an electrical signal, which is then sent to the fuel flow indicator. The fuel flow indicator, in turn, displays the fuel flow rate to the pilot or operator. This information is crucial for monitoring the engine's fuel consumption and ensuring optimal performance and efficiency.

The correct answer is inspecting other areas after isolating the trouble between points. This is not a proper troubleshooting practice because once the trouble has been isolated between specific points, it is important to focus on those areas rather than inspecting other unrelated areas. Inspecting other areas can lead to wasted time and effort, and may not effectively solve the problem at hand. It is more efficient to concentrate on the identified trouble points and perform targeted checks and repairs in those areas.

An understanding of the operating principles of engine instruments will help determine the meanings of instrument readings. By knowing how the instruments work and what they measure, one can interpret the readings accurately. This knowledge is crucial in assessing the engine's performance and identifying any potential issues or abnormalities. It enables informed decision-making regarding whether the engine should be removed from the aircraft or sent to a test cell for further examination. Additionally, understanding instrument readings aids in identifying the specific tools and maintenance procedures required to address any problems detected.

The exhaust nozzle position indicating system helps the pilot determine engine power. This is because the position of the exhaust nozzle directly affects the thrust produced by the engine. By monitoring the position of the nozzle, the pilot can have a better understanding of the engine's power output.

The N2 tachometer generator is typically driven from the tachometer drive located on the engine accessory section. This section of the engine houses various accessories such as the generator, starter, and hydraulic pump. By being driven from this section, the N2 tachometer generator can accurately measure the rotational speed of the engine's N2 turbine, which is important for monitoring engine performance and ensuring proper operation.

A typical jet exhaust gas temperature (EGT) indicating system contains thermocouples, leads, an indicator, and a resistor. The resistor is used to calibrate the EGT system and ensure accurate temperature readings. It helps to convert the electrical signals from the thermocouples into a measurable value on the indicator. The resistor plays a crucial role in the overall functionality of the EGT system by providing a reference point for temperature measurement.

The fuel-flow indicator is used to measure the rate at which fuel is flowing. In this case, the indicator is measuring the rate in pounds per hour. This means that it is showing the amount of fuel being consumed in terms of weight (pounds) over a period of one hour. This measurement is commonly used in aviation to monitor fuel consumption and ensure efficient operation of the aircraft.

The engine diagnostic unit (EDU) is responsible for acquiring fault data from the digital electronic engine control (DEEC) and logging the faults with the time of their occurrence. This unit is specifically designed for diagnosing and monitoring the engine's performance and detecting any faults or abnormalities. It plays a crucial role in analyzing the engine's health and providing valuable data for maintenance and troubleshooting purposes.

The correct answer is two silver contacts. The overheat detector unit used on aircraft engines consists of a hollow stainless steel tube that covers two silver contacts. This design allows for efficient detection of overheating in the engine. The silver contacts are specifically chosen for their conductivity and ability to withstand high temperatures. The presence of two silver contacts ensures accurate detection and reliable functioning of the overheat detector unit.

The temperature of the combustion inlet is not measured in a jet engine.

The fuel system component of a jet engine that operates by using a water wheel concept is the fuel-flow transmitter. This device measures the rate at which fuel is flowing through the engine and transmits this information to the fuel-flow indicator. The water wheel concept refers to the mechanism inside the transmitter that rotates in response to the flow of fuel, similar to how a water wheel rotates in response to the flow of water. This rotation is then converted into an electrical signal that can be used to display the fuel flow rate on the indicator.

The tachometer indicator is an electric-magnetic-drag-type instrument. This means that it uses both electric and magnetic forces to measure the speed of rotation. The drag-type mechanism allows for accurate and precise readings by creating resistance against the rotation of the instrument. This type of tachometer indicator is commonly used in vehicles to measure the engine's revolutions per minute (RPM). It relies on the interaction between electrical and magnetic fields to provide the necessary data.

A transducer is a device that converts one form of energy into another. In the case of engines with afterburners, the position of the exhaust nozzle needs to be converted into an electrical signal. Therefore, a transducer would be the most appropriate device to perform this conversion. A rheostat is a variable resistor, a rectifier converts alternating current to direct current, and a transformer is used to transfer electrical energy between two or more circuits. None of these devices would be suitable for converting the position of the exhaust nozzle into an electrical signal.
