The AP, if engaged, will disengage. The AP can be reengaged with GA Mode selected and will follow the pitch command. AVIONICS MASTER Switch – Powers the avionics bus bar or the radio CBs, AUTOPILOT and PITCH TRIM CBs ACFT MASTER Switch: can be used in an emergency to shut off all power while the problem is isolated Normal Gyro warm-up time: 3-4 minutes System Circuit Breakers - AUTOPILOT (AP/FD – Pilot’s CB panel): FCS computer, Mode Controller, Annunciator Panel, FDI, AP Pitch and Roll Servos - Avionics Master (2 CBs – Pilot’s CB panel): Avionics Bus, including FD/AP components and Electric Trim - COMPASS SYSTEM or LEFT H/G (Pilot’s CB panel): KCS 55A compass system - ELEC TRIM: FCS Autotrim, manual electric trim PA31-350 NORMAL CHECKLIST AUTOPILOT DETAILED SYSTEMS CHECK/OPERATION Version 10 N - 7 - 2 KFC 200 AFCS WITH FLIGHT DIRECTOR Detailed System Check, after Start (g) PREFLIGHT CHECK (Must be performed prior to each flight) (1) With no modes engaged and all valid flags retracted, depress the TEST Button on the Mode Controller. The YAW DAMP ON light will illuminate and all annunciators will illuminate on the annunciator panel, including the three marker lights. In addition, the red TRIM failure light will flash. At least four or more flashes must be observed to indicate proper operation of the auto trim/manual electric pitch trim feature and an audible warning should sound. (NOTE: YAW Damper is not an installed option on this aircraft) (2) With the AP disengaged, run the following manual electric pitch trim checks. a. Verify that the PITCH TRIM circuit breaker is in. b. Actuate the left-side switch to the fore and aft position. The trim solenoid should engage, but the trim should not run. Actuate the right-side switch to the fore and aft positions. The trim solenoid should not engage and the trim should not run. c. Run the trim from full nose up to full nose down. The time required is 39 +/- 4 seconds. d. Grasping the manual trim wheel, run the trim both up and down and check the overpower capability. (Check that the trim indicator moves with the wheel). e. Press the AP DISC/TRIM INTERRUPT switch down and hold. The Manual electric pitch trim will not operate either up or down. (3) Engage the FD. Then engage the AP, depress the CWS switch, center the flight controls and then release the CWS switch. Apply force to the controls to determine if the AP can be overpowered. (4) Engage the FD and AP and put in a pitch (UP) command using the vertical trim switch on the Mode Controller. Hold the PA31-350 NORMAL CHECKLIST AUTOPILOT DETAILED SYSTEMS CHECK/OPERATION Version 10 N - 7 - 3 control column to keep it from moving and observe the autotrim run in the nose up direction after approximately three seconds delay. Use the vertical trim switch and put in a pitch (DN) command. Hold the control column and observe the autotrim run in the nose down direction after approximately three seconds. (5) Engage the HDG mode and the AP. Set the HDG bug to command a right turn. The control wheel will rotate clockwise. Set the HDG bug to command a left turn. The control wheel will rotate counterclockwise. (6) Toggle the Accelerometer test switch to the (UP) position; the autopilot will disengage. Re-engage the AP and toggle the switch to the (DN) position; the autopilot will disengage. NOTE: in this aircraft the accelerometer test fails. This indicates a failed accelerometer in some way. That implies a lack of autopilot failsafe in the event of an autopilot-induced high G turn or extreme pitch command. The pilot must manually disengage the autopilot if such a condition develops. CAUTION: Operation of the Autopilot on the ground may cause the Autotrim to run because of back force generated by elevator downsprings or pilot induced forces. Therefore, disengage the AP and check that the airplane manual Pitch Trim is in the Takeoff position prior to takeoff. CAUTION: If the Autopilot circuit breaker is pulled, the red “TRIM” failure light on the Annunciator panel will be disabled and the audible warning will continuously sound indicating that the failure light is disabled. In this event the “PITCH TRIM” circuit breaker should be pulled and infight Trim accomplished by using the manual Pitch Trim Wheel. PA31-350 NORMAL CHECKLIST AUTOPILOT DETAILED SYSTEMS CHECK/OPERATION Version 10 N - 7 - 4 Normal Operation PAH mode: “Pitch Attitude Hold” mode, AP follows FDI bars In PAH, “Vertical Trim” switch will chg pitch attitude 1 degree/sec ALT mode: captures pressure altitude at time ALT is depressed In ALT hold, holding “Vertical Trim” sw will change alt 500-700 fpm, new pressure altitude when sw is released will be held HDG mode: AP holds heading set by Captains Bars on PNI (HSI). NAV mode: AP holds centerline of desired VOR radial/GPS route. Set up an intercept using HDG. Engage NAV. AP will turn to intercept when arriving on centerline (any angle up to 90o). NOTE: be aware that when executing turns at waypoints, the course needle on the PNI (HSI) must be turned to the new course before the AP will turn and track the new leg. Failure to do so may result in the aircraft continuing on its previous course/heading. The AP will use aggressive angles to intercept a course, up to 45o, unless HDG mode is used to incp. APPR mode: Engineered for VOR/ILS approaches, GPS added later, follows GPD guidance like VOR/ILS. APPR ARM will display until course incp, or APPR will display if engaged when CDI already centered. APPR CPLD displays when captured. Disengages when APPR, GA, HDG, NAV modes are selected. BC mode: proceed as for normal appch. Engage BC after APPR. BC reverses commands, cannot be engaged without a LOC freq selected. Disengages when pressing BC, APPR, GA or selecting other than a LOC freq on nav receiver. Trim up/dn switch can be used to adjust ALT hold or PAH angle for vertical guidance without disengaging the mode. GA mode: depress the GA sw on the left throttle. GA illuminates. FDI commands +7 ½o pitch angle. AP disengages, cancels all vertical modes as well as APPR or NAV CPLD. Provides guidance for missed appch, ready for new AP modes. Pilot must fly manually until new AP modes engaged. PAH Procedure: 1. Engage FD command bars appear and capture the current conditions, indicating PAH (Pitch Attitude Hold). 2. Engage AP. AP follows FDI (Flt Director Indicator), for attitude hold 3. Depress CWS SYNC to reset attitude, release and FD/AP will hold new. In PAH, “Vertical Trim” switch will change pitch attitude 1 degree/sec PA31-350 NORMAL CHECKLIST AUTOPILOT DETAILED SYSTEMS CHECK/OPERATION Version 10 N - 7 - 5 Nav/VOR Procedure: 1. Tune VOR/set GPS route 2. Set desired intercept hdg with Capts Bar 3. Engage HDG mode (max of 90o recommended) 4. Set desired adial/course on CDI 5. Engage NAV. NAV ARM displays. When acft intercepts beam/crs, acft captures beam/crs, NAV CPLD displays 6. New beam/crs may be selected over the VOR/waypoint for next leg Approach Procedure: 1. Tune VOR/ILS/Set RNAV Appch 2. Sent CDI to front course 3. Set Capts Bars and engage HDG for intercept 4. Engage APPR, APPR ARM displays 5. Approaching beam/crs, acft captures, APPR CPLD displays, HDG decouples, FDI gives commands to track LOC/VOR/CRS 6. When GS is intercepted, GS couples, GS displays, disengages ALT, set Capts Bars for missed approach but do not engage HDG 7. When MM rcvd, system will switch to a more-stable track mode NOTE: Operation of the marker test function after approach coupled will reduce the flight control system gain. If this should occur, the APPR mode should be recycled. Missed Approach Procedure: At missed approach or go around point 1. Select GA on Left Throttle 2. AP disengages, Aural alert will sound 3. FDI indicates climb pitch angle 4. Manually apply power, clean up aircraft, establish climb, re-trim acft 5. AP modes may be re-engaged (HDG, PAH) for climb out procedure Back Course Procedure: same as approach mode except: 1. Tune LOC 2. Sent CDI to front course 3. Set Capts Bars and engage HDG for intercept 4. Engage APPR, APPR ARM displays 5. Engage BC, BC displays (computer reverses commands) 6. Approaching beam/crs, acft captures, APPR BC CPLD displays, HDG decouples, FDI gives commands to track LOC 7. Descent must be managed via Vertical Trim Sw DN (500-700 fpm) in ALT hold, or PAH and Vertical Trim Sw to set descent angle 8.

If, after GS CPLD, valid is lost, the GS annunciator will flash and revert from GS CPLD to PAH with the FDI pitch steering bar providing pitch attitude steering information. If the GS valid returns, the system will revert back to GS CPLD. NAV – The NAV or APPR Modes (ARM or CPLD) may be selected and will function with or without a NAV flag present. The FDI bank steering will continue to provide steering information with or without a valid NAV signal. AP DISCONNECT Alert – will sound an audible warning for approx. 2 seconds whenever the Autopilot engage lever on the Mode Controller is disengaged. TRIM WARNING LIGHT – flashes and audible warning when: - Autotrim and/or manual elec pitch trim failures occur - Trim servo motor runs without a command (manual and auto modes) - Trim servo motor not running when commanded (auto mode only) - Trim servo motor running wrong direction (auto mode only) - AP TEST button on Mode Controller Panel is depressed EMERGENCY DESCENT (Recommended by Colemill after conversion) 1.
