What system provides attitude hold in the helicopter?

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

Answer: (A)

Attitude hold means the aircraft automatically keeps a chosen orientation (pitch and bank) without the pilot constantly making inputs. The autopilot is the system designed to do that: it uses attitude and rate information from sensors and sends corrective commands to the flight controls to maintain the commanded attitude.

Stability augmentation (SAS) helps dampen unwanted motion and makes the helicopter feel steadier, but it doesn’t lock in a specific attitude by itself. Beep Trim is used to set a fixed trim so the controls feel balanced, not to actively hold an attitude. Cutting the autopilot disables the active attitude-holding capability, so it can’t maintain the target orientation.

So, the system that provides attitude hold is the autopilot.
