5.6 GFC 700 AFCS Troubleshooting The GFC 700 is a digital Automatic Flight Control System (AFCS) which is integrated into various components of the G1000. This section touches upon key items to note while troubleshooting the GFC 700. Should a problem be encountered during the operation of the GFC 700, the pilot and technician should first evaluate the overall status and condition of the G1000 system at the AUX – System Status page (on MFD).
5.6.1 GFC Status Page The GFC Status page is presented in configuration mode and gives status information regarding the GFC 700. Figure 5-6, GFC Status Page GIA STATUS AP DISCONNECT: Shows the condition of the AP DISC +28 VDC input to the GIAs and servos, which is required for the Autopilot to operate. A green status indicator shows the AP DISC switch is closed and the GFC 700 is activly receiving 28. volts.
SERVO DATA Shows real-time reported data including servo voltage, speed, motor current, load cell torque, and clutch solenoid status. A green box indicates the servo clutch is engaged. SLIP CLUTCH TEST RESULTS This window is used during the automatic slip clutch torque measurement check. 5.6.
9. The GIA Maintenance Log can record any of the following faults: • FCS Task not started: Bad gains The FCS task has not started because the gains are not present or have been corrupted. Reload the gain files to correct. • FCS Task not started: Gain structure out of range The FCS task has not started because the gains are not compatible with the GIA software. Reload the gain files to correct.
5.6.3 GIA Pre-Flight Test Steps PFT step 0: System initialization, verify GFC powered This step is checking to make sure the GFC is powered up. It checks to make sure the GIA AP disconnect input is connected to 28 volts, and makes sure the Servos are up and communicating. If this step fails, make sure the GIA is connected to AP disconnect by using the GFC configuration page. Also make sure all configured Servos are communicating by checking for Servo product data in configuration mode.
PFT step 5: System initialization, verify servo PFT is complete This step is checking to make sure that all servos have completed their own PFT. This does not check whether the servo PFT passed or failed. It verifies that the servo PFT is no longer in progress. PFT step 6: Verify cross GIA is initialized This step is checking to make sure the other GIA is also on step 6 of its PFT. If this step fails, try cycling power on GIA1, GIA2, and all servos.
PFT step 12: Verify AP disconnect enabled This step is checking to make sure GIA1, GIA2, and all servos have are connected to a 28 volt AP disconnect. If this step fails, make sure the AP disconnect input to GIA1, GIA2, and all servos is connected and registering 28 volts. Make sure the AP disconnect switch has been installed in the aircraft. Make sure no one is holding the AP disconnect switch down on the yoke.
5.6.3.1 Servo Faults and Troubleshooting Whenever a servo fault occurs, a status message is logged to the corresponding servo control or monitor maintenance log. This information is also accompanied by a time and date stamp. An “RTC DATE” entry is made every time a servo is powered on, it is normally not useful for troubleshooting. The following is a listing of possible faults that could be reported in a GSA fault log.
PFT Faults MONITOR PFT STEP "INTERNAL COMM FAIL" NOTES This can sometimes be a result of a failure on the other internal servo board, check faults on the other processor "UNSW POWER INV" Check unit power "MON SOL PWR ON FAIL" Check unit power and AP Disconnect power "CTL SOL PWR ON FAIL" Check unit power and AP Disconnect power "SOL PWR FAIL" Check unit power and AP Disconnect power "CERT DATA UNINSTALLED" Upload the certification gain file to the Monitor board "STRAP CODE MISMATCH" Check the c
5.6.3.1.2 Control Processor The control processor contains the logs that are found in these processors – 3 – Pitch Servo 5 – Roll Servo 7 - Yaw 9 – Pitch Trim Servo There are two main groupings of faults that can occur in the control processor. The first grouping of faults can occur during the GSA unit pre-flight test (PFT). If there is a fault during PFT the unit will not be able to transition to normal mode and the only way to clear this state would be to cycle unit power.
Normal Mode Faults CONTROL FAULT "GIA DIS FAULT" NOTES Check the AP Disconnect power into the unit "HOST DATA DIF" Check the AHRS wiring to the system "HOST DATA INV" Check the AHRS wiring to the system "SVO PWR INV" Check unit power and AP Disconnect power “STRP CODE CHNG” Check the connector strap inputs to the unit “MET STUCK SWTCH” Check the MET switch inputs into the system “MET STATUS DIF” Check the MET switch inputs into the system G1000 / GFC 700 System Maintenance Manual - 200/B200 Se

Information on the installation and operation of the GFC 700 can be found by referring to Sections 6.11, 0 and the G1000 in King Air 200/B200 Cockpit Reference Guide, listed in Table 1-2.
8.2.2 AFCS Switch Checks Verify that the AFCS system buttons and switches are operating correctly by performing the following: 1. Actuate both sections of the PITCH TRIM (NOSE UP/NOSE DN) switch to activate Manual Electric Pitch Trim (MEPT). Verify the trim clutch engages and the trim wheel drives in the requested direction. Check operation in both the up and down direction. 2. Press the AP/YD DISC TRIM INTRPT switch and hold while actuating the manual electric trim switch.
14. Press the ALT key on the AFCS mode controller and verify that the ‘ALT’ annunciation is displayed in green on PFD1 and PFD2 with an altitude reference equal to the aircraft altitude (within the nearest 20 feet). 15. Press the FD key and verify that the mode annunciations and command bars are removed from the display. 8.2.3 Autopilot Clutch Overpower Check NOTE The GFC 700 uses electronic torque limiting as well as mechanical slip clutches to limit the maximum servo effort.
8.2.5 Autopilot Operation Checks NOTE For aircraft with software version 0985.03 and the Electronic Stability and Protection (ESP) option, an airspeed of 200 knots must be input using a pitotstatic test set. 1. Engage the Autopilot by pressing the AP key on the AFCS mode controller. Push the HDG knob to synchronize the heading bug to the current aircraft heading. Select HDG mode by pressing the HDG key on the AFCS mode controller. Verify the command bars are level and the control wheel is stationary.
8.2.6 VOR/LOC/GS Test Perform the following test using ramp test equipment. Operate the equipment according to the test equipment manufacturer’s instructions. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. NOTE The PFD HSI does not show a course deviation bar unless a valid VHF NAV frequency is tuned. Ensure FD is coupled to PFD1 as indicated by a left pointing arrow next to the XFR button. Simulate a VOR signal on a radial equivalent to the aircraft heading.
8.3 Maintenance Records This Post-Installation Configuration Log should be completed during the initial installation and maintained with the aircraft permanent records. Record the following information: • Part number of the G1000 software loader card used to perform software loading or software updates. • Record part and serial numbers of any LRU which was replaced. • Record any database updates which were performed during maintenance.
