Which three signals does the CSC receive?

• A. Your ADF Bearing, Your Bearing Hold, and ADF Audio Error
• B. Your Bearing Hold and ADF Audio Error
• C. Your Resolved ADF Bearing, Your Bearing Hold, and ADF Audio Error
• D. Your ADF Valid Signal, Bearing Signal, and Audio Error

Answer: (C)

The CSC relies on three specific ADF-related signals: the resolved ADF bearing, the bearing hold, and the ADF audio error. The resolved ADF bearing is the corrected direction from the ADF system that the computer uses for navigation, not the raw, potentially noisy bearing. Having a resolved value ensures decisions are based on a stable and accurate heading reference. The bearing hold provides a signal to maintain or lock onto the current bearing value, keeping guidance stable even if the raw signal fluctuates. The ADF audio error flag alerts to problems in the ADF audio path, signaling degraded or unavailable audio information that could affect interpretation of the bearing. Together, these three signals give the CSC a reliable heading reference, a mechanism to maintain it, and a warning when the audio channel is failing. Other options either use the raw bearing instead of the corrected one, omit the hold function, or substitute signals that aren’t the ones the CSC uses for this purpose.
