Pressing the ________ switch on either cyclic will switch from Level 4 Attitude Hold to Level 1 Unstabilized.

• A. Beep Trim
• B. SAS/AP Cut
• C. Autopilot
• D. APMD DCPL

Answer: (B)

Attitude Hold relies on the Stabilization Augmentation System and, if active, autopilot to keep the helicopter’s attitude steady. The SAS/AP Cut switch on the cyclic is there to quickly disable that stabilization. When you press it on either cyclic, the stabilization is cut, so the aircraft leaves Level 4 Attitude Hold and becomes Level 1 Unstabilized, meaning you must manually control the attitude. Beep Trim isn’t about turning off stabilization, and Autopilot would not accomplish the required disengagement by itself; APMD DCPL is not the control used for this transition.
