Autopilot Servo Installation, Configuration, and CalibrationAfter sensitivity is adjusted as well as it can be, PITCH GAIN, ALTITUDE GAIN, PULLRATE, VSI GAIN, G ERROR GAIN, and G ERROR LIMIT may be adjusted to furtherimprove autopilot pitch axis performance. These should be adjusted in the aboveorder. G ERROR GAIN and G ERROR LIMIT adjustments affect the most noticeablechanges while the aircraft is in turbulence. Each of these settings’ effects areexplained in the Advanced Pitch Gain and Rate Adjustments section above, and inthe individual settings menus themselves.Verify airspeed minimum and maximum values and default climb and descent verticalspeeds during altitude changesDuring an autopilot-controlled climb, verify that the time to complete the climb matches yourexpectations given the setting for the default climb vertical speed. If it does not, the climb ratemay be limited by the minimum airspeed parameter, and the ADD POWER message will bedisplayed.Likewise, during an autopilot-controlled descent, verify that the time to complete the descentmatches your expectations given the setting for the default descent vertical speed. If it doesnot, the descent rate may be limited by the maximum airspeed parameter, and the DECREASEPOWER message is displayed.If necessary, adjust the default climb vertical speed, the default descent vertical speed,maximum airspeed, and minimum airspeed as described above.At this point, all the parameters in the Pitch Axis Menu should be appropriately tuned.Execute several autopilot-controlled changes of altitude and observe the overall aircraftperformanceThere may be some interaction between pitch servo torque and sensitivity settings and it maybe necessary to repeat the above steps to achieve acceptably smooth overall autopilotresponse during altitude holds and changes.Observe and verify trim indications during altitude holds and changesFind an area with a lot of clearance above and below the aircraft’s altitude and disengage theautopilot. Then follow this procedure:1. Put the aircraft into neutral trim.2. Engage the autopilot in ALT mode (and HDG or TRK mode if desired) and allow theautopilot to maintain altitude (and heading, if engaged).3. Trim the aircraft nose down. The autopilot will maintain the target altitude, despite thenose down trim. Continue trimming nose down just until you see a trim up indicator onthe Top Bar (i.e., alternating with ). This indicator displays when the APsenses too much nose down trim.4. Trim the aircraft nose up until the indicator disappears.5. Disengage the AP to observe the state of the aircraft’s trim.10-28 <strong>SkyView</strong> System Installation Guide - Revision J
Autopilot Servo Installation, Configuration, and CalibrationRepeat the above procedure, trimming the aircraft nose up until you see the trim downindicator on the Top Bar (i.e., alternating with ). Then, trim nose down until theindicator disappears.During turbulence and small bumps the trim indicator may flash on and off. Do not take actionbased on the trim indicator until it remains on for several seconds.Verify Overall Autopilot PerformanceEngage both roll and pitch servos and execute a number of autopilot-controlled changes ofheading, altitude, and combinations of the two and observe the overall aircraft performanceunder autopilot control.There may be some interaction between the various pitch and roll servo settings, so it may benecessary to repeat some of the later steps in each axis’ procedure while adjusting torque andsensitivity to completely optimize the autopilot for the aircraft.<strong>SkyView</strong> System Installation Guide - Revision J 10-29
