Built-in Tests (BIT) are used for what?

• A. OK/GO
• B. Manual Test Series
• C. Built-in Tests
• D. External Certification Tests

Answer: (C)

Built-in tests are self-diagnostic routines embedded in a system that run to verify its own operation. They check hardware, firmware, and essential software to ensure everything is functioning correctly without needing external test equipment. Because of this self-check capability, BIT is used to confirm the system is ready and to detect faults early, aiding maintenance and reliability. The other options describe external or manual processes or simple status indicators, not the embedded diagnostic capability represented by BIT: a simple OK/GO is just a status cue, a manual test series requires a human operator and external tools, and external certification tests involve third-party validation.
