True or False: The A220 aircraft has circuit breakers.

• A. False
• B. True
• C. Not specified
• D. Both

Answer: (A)

The idea being tested is how modern aircraft protect electrical circuits. In many newer airframes, the protection of electrical loads isn’t done with the traditional, manually resettable circuit breakers you’d find on older airplanes. Instead, the A220 uses an integrated electrical power distribution system with electronic protection that monitors faults and automatically isolates or reconfigures power as needed. This means there aren’t the familiar cockpit panels of circuit-breaker switches you pull to reset a circuit. This electronic protection approach improves reliability and ease of maintenance by removing the need to manually reset breakers and by enabling faster, software-driven fault handling. So the statement is false because the A220 relies on electronic protection within its power system rather than traditional circuit-breaker hardware.
