Autopilot Servo Installation, Configuration, and Calibration

SkyView System Installation Guide - Revision R 10-21

Figure 69–Top Bar SPD Indicator

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 70 - 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 page 5-7

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 3-8 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.

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 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, 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

69 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:
