Which switch on the cyclic would you use to disable the backup SAS?

Explanation:
The main idea here is that to stop automatic stabilization you use a dedicated cut switch on the cyclic. The SAS/AP Cut switch is exactly for this: flipping it disables the stability augmentation system and the autopilot, giving you full manual control. In an abnormal situation, you want to remove automatic inputs from the back‑up stabilization so you can fly the helicopter directly with the cyclic. The other options don’t serve this purpose. A switch labeled APMD DCPL isn’t the control for disabling SAS, Beep Trim is for a trim/beep function, and Autopilot by itself would only affect the autopilot, not necessarily the backup SAS.
