ADF audio error from your radios is your what?

• A. Output
• B. Input
• C. Indicator
• D. Monitor

Answer: (B)

The main idea here is how signal flow works in avionics. An ADF audio fault is describing a problem with the audio signal as it enters your aircraft’s audio chain—the input side. In other words, the issue is with what the system receives from the ADF receiver, not with what the system outputs, what the instrument displays, or what you monitor. So it’s categorized as an input problem.
