What is the voltage of the electrical system for the flight test aircraft?

• A. 12V
• B. 24V
• C. 14V
• D. 28V

Answer: (C)

The voltage of the electrical system for the flight test aircraft is typically 28V. This standard has been established based on the majority of general aviation aircraft that use 28V because it allows for more efficient operation of electrical components and is suitable for powering a range of systems effectively. In practice, a 28V system is preferred for its superior performance, particularly when dealing with larger loads or systems that require more power, such as avionics and lighting. It minimizes voltage drop over longer distances and supports the need for greater current, which is vital in modern aircraft that rely on various electrical components. While 12V systems are common in smaller, simpler aircraft or automotive applications, they do not typically meet the demands of more complex aircraft systems. Therefore, acknowledging that the 28V standard is used helps pilots and technicians understand how to properly manage and maintain electrical systems in flight and ground operations.
