• Vertical Speed – Maintains the current aircraft vertical speed while the aircraft is climbing/descending to the
Selected Altitude
• Flight Level Change – Maintains the current aircraft airspeed while the aircraft is climbing/descending to the
Selected Altitude
• Glideslope – Intercepts and tracks the glideslope on approach
• Go Around – Automatically disengages the autopilot and commands a constant pitch angle and wings level
The following table lists each pitch mode with the corresponding control and annunciation. The mode
