Pressing the CD Release disengages which autopilot modes?

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

Answer: (A)

The important idea is how autopilot control is separated by axes. The CD Release specifically disables the roll-related autopilot guidance, so the airplane stops following Bank Angle Hold and Heading Hold. You’re left with vertical guidance, like Pitch Hold and Altitude, still available if those modes were engaged. So the correct choice is the pair that governs the roll axis. The other options refer to vertical modes or non-rolling functions that aren’t disengaged by the CD Release.
