12. Autopilot Ground Test Procedures: 12.1. Reengage circuit breakers, clear propeller area and turn on the Master and Avionics
Switches. 12.2. Check that the autopilot circuit breaker is engaged. Place the autopilot master switch
in the "AP" position. All segments of the programmer/computer display should illuminate including: HDG, RDY, NAV, CWS, APR, FAIL, TRIM ơ, ALT, GS, VS, +16. The software revision number will briefly appear after 10 to 20 seconds after which only the RDY annunciation will remain illuminated indicating the system is ready to engage.
12.3. Depress button "HDG", the roll solenoid should be heard to engage. A green "AP" should appear on the "Mode Indicator" above the PFD.
12.4. Depress Button "ALT", the pitch servo solenoid should be heard to engage. 12.5. Depress and release control wheel steering switch, (blue switch on pilot's control
wheel). "CWS" and "VS" modes will annunciate and "HDG" and "ALT" will extinguish. Move aircraft controls to determine that the roll and pitch servos are engaged.
12.6. Depress and release the control wheel disconnect switch, (red button on pilot's control wheel). "RDY" will flash and then annunciate steady. An audible tone will indicate autopilot disconnect. Check to see that the roll and pitch servo solenoids are disconnected.
12.7. Center the heading bug on the G500, (select the heading "HDG" bezel key on the PFD and depress the center PFD Knob, (lower left knob on G500Display)).
12.8. Depress the "HDG" mode selector switch on the programmer/computer. "HDG" will annunciate and "RDY" will extinguish. Rotate the heading bug to the right and then to the left of the center indicator and note that the control wheel movement follows the direction of the commanded input. Re-center the PFD heading bug.
12.9. Ensure that the control wheel remains motionless, otherwise adjust the roll centering, (3 turn potentiometer accessible through the face plate between the "REV" and "ALT" mode selector switches), for zero roll servo activity. (Note this adjustment will be further verified during Flight Testing).
12.10. Move elevator to a mid-travel position and select VS mode to engage the pitch servo. Turn the VS knob clockwise to select a positive vertical speed and observe the control

wheel's travel aft or pitching nose up. Select a negative vertical speed (VS knob counterclockwise) and observe control wheel moves slowly in or aircraft nose down. Note: Flashing "VS" annunciator during this test may or may not occur. Flashing "VS" indicates system is unable to resolve a vertical speed error, a condition that may occur during ground test.
12.11. OVERPOWER - Grasp control wheel and overpower autopilot in both roll and pitch. Be alert that no excessive play exists in the control system and/or between the control system and the roll and pitch servos.
12.12. Momentarily depress control wheel disconnect switch - move control wheel in roll and pitch and assure that the roll and pitch servos have disconnected and that the controls are free. The "RDY" light should illuminate flashing for 5 seconds and then be steady, along with an audible tone, indicating autopilot disconnect.
12.13. Trim Test - Move elevator control to a mid travel position and re-engage "HDG" and "VS" modes. Apply forward pressure, (nose down), to elevator control and hold for 3 seconds minimum. "TRIM ▲" should annunciate for 4 seconds. After 4 seconds the "TRIM ▲" will begin flashing. Apply aft pressure on the control wheel, (nose up), and hold for 3 seconds minimum - observe the same annunciations with the "TRIM ▼" annunciator. Hold control wheel and disengage autopilot.
12.14. Tune the Navigation receiver to the local OMNI station or simulate signal and center the needle on the G500 HSI display. Select "NAV" mode on the programmer/computer and rotate the OMNI bearing selector right and then left. Control wheel should move right with right needle deflection and left with left needle deflection. Note, when "NAV" or "REV" mode is selected and no valid navigation information is present, the "FAIL" annunciator should illuminate and the respective mode light will flash.
12.15. Channel an ILS radio frequency. Select "APR" and "ALT" modes. Select "APR" mode a second time - the "ALT" annunciations should remain illuminated with a flashing "GS". Select "APR" once again to return to "APR" (normal). Select "ALT" mode. Select "ALT" mode a second time to arm/engage "GS", ("ALT" extinguishes). Hold control wheel and disengage autopilot.
12.16. To check "GPSS", engage the autopilot "HDG" mode. Push the "NAV" mode button twice, (2 times), "GPSS" should annunciate, (this will require a valid GPS signal). The "GPSS annunciator will also flash if ground speed and bank angle labels are not received from GPS navigator. Select "NAV" once again to return to "NAV" (normal). The aircraft will need to be flight tested to check operation of GPSS. Hold control wheel and disengage autopilot.
13. Turn OFF all master switches.

H. Flight Adjustments and Flight Tests Before take-off the pilot in command shall perform all the preflight and ground checks applicable to the autopilot system as specified in the flight manual supplement P/N S03. In-flight Adjustment: The in-flight adjustments for this system consist of one 3 turn adjustable potentiometer (roll centering) located behind the face plate of the programmer/computer and accessible with a small slot screwdriver, through the hole in the face plate between the "REV" and "ALT" mode switches, See Figure 13. 1. Fly the aircraft into smooth air, and trim for level flight. 2. Ensure autopilot circuit breaker is engaged and toggle AP Master Switch to "AP". 3. Center the heading bug on the G500 HSI and engage "HDG" and "ALT" modes on the
programmer/computer. 4. Select a desired radial on the navigation receiver or use the "CRS' selector on the G500.
Engage "NAV" mode on the programmer/computer and allow the aircraft time to establish on course.
5. Check roll center adjustments in "NAV" mode after system has timed out to "NAV-SOFT" and fine adjust (if necessary) to fly a centered needle. (Assuming the aircraft is already close to the desired course selection the AP should achieve "NAV-SOFT" in less than 5 minutes. See section "3.1.2 Navigation (NAV) Mode" of the S-Tec POH for further explanation of the various navigation modes and associated gain changes). Select "HDG" mode and check heading bug centered ±3°.
Note: The roll centering potentiometer is a 3 turn potentiometer and should be adjusted in very small increments. Allow sufficient time between adjustments for the system to stabilize. Clockwise rotation of the potentiometer produces right turn and counterclockwise produces left turn. Note: If the rudder is incorrectly trimmed, the autopilot will cause the aircraft to fly with a wing low in an effort to maintain the selected heading. Note: The pitch system does not require flight adjustments.

Flight Tests: The following tests may be performed in any order. 1. VS Verification:
1.1. AP in "HDG or NAV" and "VS" 1.2. Select a "VS" for 90 to 100 KIAS Note: The commanded and indicated vertical speeds should be approximately the same once the aircraft stabilizes. Caution: For a given altitude the autopilot can command vertical speeds in excess of the aircraft capabilities. This could result in the aircraft stalling. An irresolvable vertical speed will be announced by a flashing "VS". 1.3. Perform a pitch deviation of -10° and release. (This should be a "Crisp" input resulting
in an altitude change of less than 200'). The pitch oscillations should be damped in approximately 2 cycles.
1.4. Set aircraft to a 0.9 Vne, (≃ 172 KIAS), @ MCP descent. 1.5. Perform a pitch deviation of +10° and release. (This should be a "Crisp" input). The
aircraft should return to it's former attitude and the pitch oscillations should be damped in approximately 2 cycles.
2. ALT Verification: 2.1. Establish the aircraft in a stable climb, (let the aircraft stabilize but be aware of the
degradation in performance with altitude. Set a climb rate appropriate for the altitude). The commanded VS and G500 indicated VS should match.
2.2. Establish the aircraft in a stable descent, (let the aircraft stabilize). The commanded VS and G500 indicated VS should match. Do not exceed 0.9Vne or 172 KIAS.
2.3. Manually set aircraft in a trimmed normal cruise and engage autopilot in "HDG/NAV" and "ALT". Cruise for 5 minutes. In "ALT" mode the AP shall maintain an altitude tolerance of ±20 ft with a maximum excursion between plus or minus altitude over a time period of 5 minute in calm air, the results being imperceptible to the pilot.
2.4. Perform a pitch deviation of +10° deviating approximately 200 ft from altitude and release. The AP shall recover from upset within 1.5 cycles to 1/10 amplitude. Pitch corrections in altitude hold should cause imperceptible g changes.
3. Altitude Preselect, (if installed): 3.1. Set an altitude of 1000 ft above the current altitude on the G500 display. 3.2. Engage dual mode by depressing "ALT" and "VS" simultaneously.
3.3. Select a vertical speed appropriate for the aircraft's altitude, (ex. ≃500 fpm). 3.4. As the aircraft approaches the desired altitude the autopilot will automatically gradually
reduce the climb, (or descent), to 200 ft/min just before capture. Overshoot should be less than 20' with a smooth return to altitude at which time "VS" will extinguish and "ALT" shall remain.
4. Manual "ALT" Capture:

4.1. This function is performed simply by the pilot depressing the "ALT" mode switch while in the "VS" mode.
4.2. Set the aircraft into a 1500 fpm descent, ("HDG" and "VS" mode). 4.3. Once established select "ALT" at a convenient altitude. A maximum 10% overshoot is
permissible with a smooth return to the pressure altitude at time of capture. 5. HDG Verification:
5.1. Select "HDG" and "ALT" on the programmer/computer. 5.2. Rotate the heading knob, (PFD knob, (lower right on G500 display)), left 90°. 5.3. Aircraft should roll smoothly into a 90% standard rate one banked turn. 5.4. When turning to a commanded heading the aircraft should not overshoot/undershoot that
heading by more than 3 degrees. 5.5. Rotate heading bug right 90°, again, the aircraft should not overshoot/undershoot that
heading by more than 3 degrees. 5.6. Track heading bug for 5 minutes. While tracking the heading bug in smooth air the
aircraft heading should be maintained to within 2 degrees of the lubber line, (up to 5 degrees in moderate turbulence).
5.7. Perform rapid 20° roll upsets left or right and release controls. 5.8. Corrections from upsets should be smooth and without overshoot, (critically damped).
6. NAV Verification: 6.1. Place navigation receiver in GPS mode, (may be done at G500 display or at receiver). 6.2. Orient aircraft 90° to intended course. 6.3. Execute a "Direct-To" on the GPS. 6.4. Engage "NAV" twice on the autopilot. 6.5. "NAV" and "GPSS" will be displayed on the AP. 6.6. After interception, track GPS course for 10 Nm. In "NAV GPSS" mode, the AP should
have a cross track error of <0.7 Nm during enroute and approach phase. 6.7. Engage the navigation receiver in VLOC select an active signal. 6.8. Engage the autopilot in "NAV" mode. Track VOR course for 10 Nm. 6.9. The autopilot should track ± within a needle width, (or two). 6.10. Track over the VOR Station from 5Nm before to 5 Nm beyond. 6.11. The autopilot in VOR "NAV" mode should provide smooth passage with a minimum
or no roll oscillations, (wing rocking). 6.12. Turn off navigation receiver. 6.13. "NAV" will alternately flash with "FAIL", steering bars will flash, AP will track
course arrow. 6.14. Turn on navigation receiver. 6.15. Once receiver has completed self test, "NAV" will reengage, aircraft will maneuver to
intercept course. 7. Approaches:
7.1. GPS Approach: 7.1.1. Place autopilot in "GPSS" mode, (press "NAV" twice) 7.1.2. Engage navigation receiver in GPS mode. 7.1.3. While tracking a GPS signal, after CDI centers, the maximum cross-track error is
0.07Nm in smooth air, (0.12 Nm allowed in moderate turbulence).

7.1.4. A minimum two leg GPS approach shall be programmed, (ex. fly to IAF then to FAF then to the DA).
7.1.5. Turns should be anticipated with little or no overshoot. 7.2. ILS Approach:
7.2.1. Engage autopilot in "HDG" & "ALT" mode. 7.2.2. Place navigation receiver in VLOC and tuned to an active localizer. 7.2.3. Aircraft assumes a 45° intercept angle. 7.2.4. The CDI will be at full scale deflection, (this assumes that the aircraft was not
already on the course when the "NAV" function was engaged). 7.2.5. "APR" is displayed and the aircraft is on a 45° intercept to inbound course. 7.2.6. An overshoot of 50% of CDI is allowed. 7.2.7. Engage "APR". 7.2.8. CDI < 50%. 7.2.9. If aircraft is < 60% below glideslope center line for 10 seconds "GS" will be
armed and AP will display "APR" & "ALT". 7.2.10. Once established on LOC course, maximum allowable deviation in smooth air is
10% CDI deflection, (20% allowed in moderate turbulence). This evaluation should be made after the aircraft is stabilized on course for at least 3 minutes.
7.2.11. Capture of glideslope occurs when GS deviation is <50%. 7.2.12. Glideslope CDI deviations should not exceed 20% full-scale deflection except for
short excursions caused by turbulence that should be quickly resolved. Tracking quality should be maintained to the middle marker, (200' AGL)
7.3. Reverse Mode: 7.3.1. Engage autopilot in "HDG" & "ALT" mode. 7.3.2. Place navigation receiver in VLOC. 7.3.3. CDI should be at full scale deflection, (ie aircraft heading shall be other than the
BC approach. 7.3.4. Set course to inbound LOC, the aircraft should now be on an intercept course. 7.3.5. Depress the mode selector switch "REV". "REV" should be displayed. 7.3.6. In "REV" mode during a 45°intercept at cruise speeds up to 160 KIAS the
maximum allowable overshoot is 25% CDI deflection from center. Note, the intercept should be made at least 4Nm from the navigation source when evaluating intercept quality.
