If 1 SAS is turned off, what happens to the remaining SAS?

If 1 SAS is turned off, what happens to the remaining SAS?

• A. The remaining SAS will double its output.
• B. The remaining SAS will shut down.
• C. The remaining SAS will switch to standby.
• D. The remaining SAS will remain unchanged.

Answer: (A)

The Stabilization Augmentation System in a dual-channel setup is designed so that each channel shares the stabilization authority. If one channel is turned off, the remaining channel increases its output to compensate and maintain the same level of stabilization, effectively delivering full stabilizing force. This redundancy keeps the helicopter controllable even with one channel inoperative. So the remaining SAS will double its output to maintain stability. The other options would imply a loss of stabilization, no change, or switching to standby, which isn’t how the system is designed to behave.
