B INTRODUCTION 9. 1 INTRODUCTION NOTE: This Pilot's Guide assumes that the reader is already familiar with the G1000 Integrated Cockpit System. Refer to the G1000 Cockpit Reference Guide and G1000 Pilot's Guides for further information concerning the G1000 system. IMPORTANT: The information contained in this guide is always superseded by the approved Airplane Flight Manual Supplement. Autopilot -- Autopilot operation occurs within the pitch, roll, and pitch trim GSA 81 servos and provides: · Automatic Flight Control · Servo Monitoring Yaw Damper -- Yaw damper operation is provided by the GSA 81 yaw servo and includes self monitoring. GIA 63 Integrated Avionics Units AFCS OVERVIEW The GFC 700 is a digital Automatic Flight Control System (AFCS) which is fully integrated within the G1000 system avionics architecture. [. . . ] Turns are commanded in the same direction as the bug movement, even if the bug is turned more than 180 degrees from the present heading (e. g. However, heading bug changes of more than 340 degrees at a time result in a turn reversal. NOTE: Pressing the CWS button and hand-flying the aircraft does not change the Selected Heading. The Autopilot guides the aircraft back to the Selected Heading upon releasing the CWS button.

B Garmin G1000 AFCS Pilot's Guide for Beechcraft A36/G36 9-15 FD MODES Navigation Mode (GPS, VOR, LOC, or BC) The Navigation mode acquires and tracks the selected navigation receiver on the HSI (e. g. The Flight Director follows GPS roll steering commands when the HSI is in GPS mode, and creates roll steering commands from the Selected Course and deviation when the HSI is in VOR, LOC, or BC modes. Note that the selected navigation receiver must have a valid signal (VOR, LOC) or active GPS course (GPS) in order for the Flight Director to enter Navigation mode. The Navigation mode can be used to fly non-precision GPS and LOC approaches where glideslope tracking is not required. It also automatically selects Backcourse mode when the localizer front course is greater than 105 degrees from the aircraft heading. Navigation Mode is active, using GPS source NOTE: When making a backcourse approach, set Selected Course to the localizer front course. Navigation/Approach Mode Armed If the course deviation indicator is greater than 1 dot when the Navigation or Approach modes are selected, the mode is automatically armed. The armed annunciation appears in white to the left of the active roll mode as shown in Figure 9. 3. 11. Navigation/Approach mode (GPS selected on HSI) is armed Figure 9. 3. 11 Approach Mode Armed Flight Level Change Mode is active, Altitude Hold is armed Flight Director command bars indicating a left turn to track GPS course and a climb to intercept Selected Altitude Selected Course GPS is active navigation receiver on the HSI Figure 9. 3. 12 Navigation Mode 9-16 Garmin G1000 AFCS Pilot's Guide for Beechcraft A36/G36 190-00609-00 Rev. B FD MODES Approach Mode (GPS, VAPP or LOC) The Approach mode acquires and tracks the selected navigation receiver on the HSI (GPS, VOR or LOC). This mode uses the selected navigation receiver deviation and desired course inputs to fly the approach. The Approach mode provides greater sensitivity for VOR tracking than Navigation mode, and allows the Autopilot to fly an ILS approach with a glideslope. NOTE: The Glideslope mode is automatically armed when LOC mode is selected. NOTE: Pressing the CWS button and hand-flying the aircraft does not change the Selected Course while in Navigation or Approach modes. The Autopilot guides the aircraft back to the Selected Course (or GPS Flight Plan) when the CWS button is released.

B AUTOPILOT 9. 4 AUTOPILOT AND YAW DAMPER OPERATION OVERVIEW The Autopilot controls the aircraft pitch and roll attitudes, while following commands received from the Flight Director. Pitch autotrim provides trim commands to the pitch trim servo, to relieve any sustained effort required by the pitch servo. The Yaw Damper reduces Dutch roll tendencies and coordinates turns. Autopilot Disengagement Automatic Disengagement Automatic disengagement typically occurs due to a system failure. Automatic disengagement is indicated by a flashing red `AP' annunciation and by the Autopilot disconnect aural alert, which continue until acknowledged. To acknowledge the disconnect, the pilot can press the AP DISC button or the MET ARM switch. For the Yaw Damper, automatic disengagement will occur when the Autopilot disengagement is caused by a failure in a parameter that also affects the Yaw Damper. This means that the Yaw Damper can remain operational in some cases where the Autopilot will automatically disengage. [. . . ] Upon being given vectors from ATC, the pilot sets the Selected Heading and presses the HDG key. The Autopilot turns the aircraft to the desired heading. 33 30 0 2. 3. The pilot uses the Heading mode to comply with ATC vectors, as requested. In preparation for the approach and at the pilot's discretion, the pilot tunes the localizer frequency, then selects the LOC mode on the HSI. [. . . ]
