When the CD Release is pressed, which autopilot modes are suspended?

• A. Bank Angle Hold and Heading Hold
• B. Velocity, Decel, PSN, LVL
• C. FD lateral and longitudinal coupling
• D. Pitch Hold and Altitude

Answer: (B)

Pressing the CD Release frees the autopilot from the speed and navigation-related commands it’s actively enforcing, so you can manually control the airplane without the autopilot trying to hold a target airspeed, a commanded deceleration, a fixed position, or a level attitude. Those four modes—velocity (speed control), decel (deceleration target), PSN (position hold), and LVL (level hold)—are the ones that are suspended. Other autopilot functions, such as lateral bank angle or heading control, flight director guidance, or vertical modes like pitch hold or altitude, are not canceled by this action, so they remain available as you fly manually or as the guidance system continues to provide cues.
