- Chapter 9: Aircraft Electrical System › Generator Controls › Functions of Generator Control Systems
When field current is controlled, generator output is controlled. Keep in mind, this system is manually adjusted and would not be suitable for aircraft. Aircraft systems must be automatic and are therefore a bit more complex. There are two basic ... types of generator controls: electromechanical and solid-state (transistorized). The electromechanical type controls are found on older aircraft and tend to require regular inspection and maintenance. Solid-state systems are more modern and typically considered to have better reliability…
- Chapter 9: Aircraft Electrical System › DC Generators & Controls › Generator Ratings
Generator Ratings A DC generator is typically rated for its voltage and power output. Each generator is designed to operate at a specified voltage, approximately 14 or 28 volts. It should be noted that aircraft electrical systems are designed ... operate at one of these two voltage values. The aircraft’s voltage depends on which battery is selected for that aircraft. Batteries are either 12 or 24 volts when fully charged. The generator selected must have a voltage output slightly…

output is not within the specified tolerance, then the generator contactor is not allowed to connect the generator to the load bus. Reverse Current Sensing If the generator cannot maintain the required voltage level, it eventually begins to draw current ... instead of providing it. This situation occurs, for example, if a generator fails. When a generator fails, it becomes a load to the other operating generators or the battery. The defective generator must be removed from the bus. The reverse…
