Loss of AFCS 2 results in loss of which DAFCS function?

• A. ALT Hold
• B. Airspeed Hold
• C. Attitude Hold
• D. Heading Hold

Answer: (B)

This tests how the AFCS channels map to hold modes. In this aircraft, the airspeed hold function is tied to AFCS 2. When AFCS 2 is lost, the system can no longer automatically maintain a commanded airspeed, so airspeed hold is lost. Other hold modes—altitude, attitude, and heading—are handled by the remaining channel (AFCS 1) or are not dependent on AFCS 2, so they stay available. So the function that disappears with the loss of AFCS 2 is airspeed hold.
