How is the AFCS self-test completed?

Explanation:
AFCS self-test happens during the system’s power-up sequence and is triggered when the Avionics 1 bus is powered. Once Avionics 1 is active, the AFCS control computers, servos, sensors, and related paths are exercised to verify they’re functioning correctly. If that bus isn’t powered, the self-test can’t run, so the AFCS won’t be checked or become available. External power might power other parts, but the test requires Avionics 1 power specifically. The other moments listed (after landing or after AP disconnect) aren’t when the self-test is performed.
