How many batteries are used in the aircraft’s electrical system?

• A. 1
• B. 2
• C. 3
• D. 4

Answer: (B)

In the context of aircraft electrical systems, having two batteries is a standard configuration in many types of commercial and general aviation aircraft. This dual-battery system enhances reliability; if one battery fails, the other can take over to ensure the uninterrupted operation of critical electrical systems. Additionally, having two batteries can provide redundancy for backup power, supporting essential functions such as avionics, emergency lighting, and other vital electrical components. This setup is particularly beneficial in larger aircraft where the failure of a single battery could compromise safety and operational capabilities. The dual-battery system also aids in performing maintenance checks and managing electrical loads more efficiently. Hence, the correct choice reflects common engineering practices aimed at ensuring safety and reliability in aircraft design.
