ROLL MODES

The GFC 700 offers the following roll modes:
• Roll Hold (default mode) — Holds the current aircraft roll attitude or rolls the wings level, depending on the
commanded bank angle
• Heading Select — Captures and tracks the Selected Heading
• Navigation — Captures and tracks the selected navigation source
• Backcourse — Captures and tracks a localizer signal for backcourse approaches
• Approach — Captures and tracks the selected navigation source with greater sensitivity for approach
• Go Around — Commands a constant pitch angle and wings level while in the air
The following table relates each roll mode to its respective control and annunciation. Refer to the pitch modes
section for information regarding Go Around Mode.
The CWS Button does not change lateral references for Heading Select, Navigation, Backcourse, or Approach
modes. The autopilot guides the aircraft back to the Selected Heading/Course upon release of the CWS
Button.
