AP Servo Installation and Configuration
SkyView HDX System Installation Manual - Revision E 16-5
If the aircraft’s altitude rises above the target altitude bug and the autopilot cannot pitch
the aircraft down without going above the maximum airspeed, SkyView presents the
prompt:
Figure 107; Top Bar Airspeed High Indication
The maximum airspeed parameter cannot be set to a value above 95% of Vne, which
should be set to the specifications of your aircraft in the Airspeed Limitations Menu
(reference Airspeed_Limitations on Page 7-10 for more information) and is specified in
the units set in the Measurement Units Menu (i.e., miles per hour, knots, or kilometers
per hour; reference Page 21-7 for more information regarding configuring the
measurement units). As mentioned previously, the maximum value for this parameter is
95% of Vne. This is also the default value.
To set the maximum airspeed:
1. Go to the Pitch Axis Maximum Airspeed Adjust Page (SETUP MENU >
AUTOPILOT SETUP > PITCH AXIS > MAXIMUM AIRSPEED).
2. Adjust the maximum airspeed.
3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.
16.2.3.4 Minimum Airspeed
If the AP is engaged and the Minimum Airspeed limit is changed to a value
that is higher than the current airspeed, the AP will immediately act to increase
the airspeed to the new minimum airspeed setting. Dynon Avionics
recommends that this setting only be adjusted with the AP disengaged.
The pitch axis minimum airspeed is the lowest airspeed at which the pilot may engage
the autopilot. The autopilot cannot be engaged at airspeeds below the minimum airspeed,
with the exception of 0 knots (0 km), allowing for ground testing.
When flying at airspeeds lower than the minimum airspeed or when the autopilot is
engaged, and the aircraft airspeed drops below the minimum, SkyView indicates that the
aircraft has dropped below the parameter by displaying SPD indicators in the Top Bar as
illustrated in Figure 106 above.
If the aircraft’s altitude drops below the target altitude bug and the autopilot cannot pitch
the aircraft up without dropping below the minimum airspeed, SkyView presents the
prompt:
Figure 108: Top Bar Airspeed Low Indication
The minimum airspeed parameter must be set to at least (and defaults to) 30% above
VS1, which should be set to the specifications of your aircraft in the Airspeed Limitations
