Observe the autopilot status indicator on the Top Bar while the autopilot flies. If the
banner is shown frequently, it is an indication that the pitch servo is slipping and
the servo torque needs to be increased. Occasional slips due to turbulence are acceptable.
If frequent PITCH SLIPS are observed, disconnect the autopilot and increase PITCH TORQUE by
10% (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > TORQUE).
If you have adjusted the pitch servo torque to 100% and are still seeing frequent
slips, you may need to try a higher strength servo (e.g., if you have an SV32
installed, try swapping for an SV42). Contact Dynon for assistance.
7. Check if aircraft lags FD command bars
Observe the speed at which the autopilot responds to changes in IAS setting, and if the aircraft
lags behind the Flight Director command bars.
If the autopilot seems too slow to respond or "sluggish", disconnect the autopilot and increase
PITCH SENSITIVITY by 2 (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > SENSITIVITY).
If you have adjusted the pitch servo sensitivity to its maximum setting and are still
observing unacceptably slow behavior, contact Dynon for assistance.
8. Check if aircraft is "twitchy" in PITCH axis
Observe if the flight controls twitch excessively or seem overly aggressive.
If it does, this is an indication that the PITCH SENSITIVITY needs to be decreased. Decrease
PTICH SENSITIVITY by 1 (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > SENSITIVITY). There
is no need to disconnect the autopilot before making this change.
After making this adjustment, increase the IAS target by 10 knots, and check if the autopilot
overshoots the new IAS target. If IAS target overshoot is observed, disconnect the autopilot,
increase PITCH GAIN by 0.2 (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > GAIN) and start
over. Otherwise, proceed to the next step.
9. Check if aircraft overshoots IAS target
Observe if the autopilot is overshooting or wandering around the IAS target. The autopilot
should keep the open triangle of the IAS bug closely aligned with the IAS pointer on the
airspeed tape.
If an overshoot is observed and you made a recent PITCH GAIN adjustment, disconnect the
autopilot, increase PITCH GAIN by 0.2 (SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > GAIN)
and start over
Otherwise, if you have not made a recent PITCH GAIN adjustment:
1. If PITCH SENSITIVITY is maxed out, disconnect the autopilot, increase PITCH GAIN by 0.2
(SETUP MENU > AUTOPILOT SETUP > PITCH AXIS > GAIN) and start over
