Autopilot Servo Installation, Configuration, and Calibration
10-18 SkyView System Installation Guide - Revision K
Default Descent Vertical Speed
The default descend vertical speed parameter sets the average speed the autopilot will
command for descents when the pitch axis is configured in the VS:DFLT mode. You may also
control the climb vertical speed with the vertical speed bug in VS:BUG mode. Reference the
SkyView Pilot’s User Guide for more information on these two modes.
The default descend vertical speed parameter is specified in the units set in the Measurement
Units Menu (i.e., feet per minute or meters per second; reference page 3-8 for more
information regarding configuring the measurement units). The default value is 500 feet per
minute and the value is adjusted in 1 unit increments. The maximum value is 3,000 feet per
minute.
To adjust the default descend vertical speed:
1. Go to the Pitch Axis Default Descend Vertical Speed Adjust Page (SETUP MENU >
AUTOPILOT SETUP > PITCH AXIS > DEFAULT CLIMB VERTICAL SPEED).
2. Adjust the default climb vertical speed.
3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.
Maximum Airspeed
If the AP is engaged and the Maximum Airspeed limit is changed to a value that is
lower than the current airspeed, the AP will immediately act to reduce the airspeed
to the new maximum airspeed setting, and may do so aggressively. Dynon
recommends that this setting only be adjusted with the AP disengaged.
The pitch axis maximum airspeed parameter is the highest airspeed at which the pilot may
engage the autopilot. If the autopilot is engaged at the time the aircraft’s airspeed exceeds the
maximum, the autopilot enters an airspeed hold mode and pitches the aircraft up to prevent
increasing airspeed. SkyView simultaneously indicates that the aircraft has exceeded the
parameter by displaying SPD indicators in the Top Bar and in the AP menu as illustrated in
Figure 59 and Figure 60, respectively.

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:
REDUCE POWER
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.,
