ATPL Theory

Autopilot Cws Mode


🕹️ Control Wheel Steering (CWS) — Simple Explanation

CWS is an autopilot mode that lets the pilot manually steer the aircraft using the control column or wheelwithout fully disconnecting the autopilot.


⚙️ How It Works

  • When CWS is engaged, the autopilot stays active, but it follows the pilot’s control inputs.
  • The pilot moves the control wheel or column → sensors send signals to the autopilot → autopilot moves the control surfaces accordingly.
  • When the pilot releases the control, the autopilot holds that new attitude (pitch and/or roll).

🧩 Key Points

Function Description
Purpose Allows manual control through the autopilot system
Axes Pitch (CWS P) and/or Roll (CWS R)
Display Shown on the Flight Mode Annunciator (FMA)
Control feel Similar to manual flying
When pressure released Autopilot holds current attitude
Flight Director (FD) Still shows guidance, but A/P doesn’t follow it in CWS mode

In short:

CWS lets the pilot “fly through” the autopilot — move the controls manually, and when released, the autopilot holds the new attitude automatically.
