What test fire is run after a PAC-fire?

• A. PSOT 498
• B. PSOT 499
• C. PAC-TEST
• D. FIRE-X

Answer: (B)

This item tests understanding of the test-fire sequence that follows a PAC-fire and which verification step is used to confirm the system’s post-event status. After performing a PAC-fire, the next test is specifically designed to verify that the system reset correctly, safety interlocks are intact, and diagnostics show normal results. That post-fire verification is the higher-numbered PSOT in the sequence, which is why PSOT 499 is the correct choice. The other options correspond to different steps or checks: an earlier test in the sequence, a test that validates the PAC mechanism itself, or a separate validation not tied to the post-fire verification.
