Advanced Pitch Gain and Rate Adjustments
There are several additional advanced parameters that can be used to fine tune the
performance of the pitch axis. They should be considered secondary to the primary Pitch Axis
Sensitivity adjustment. When used, they should be adjusted in the following order:
Pitch Gain: Use only after sensitivity is set as well as it can be. Increase gradually if
airplane does not settle on altitude. The default setting is 2.
Altitude Gain: Use only after sensitivity and all of the above settings are set as well as
they can be. Increase gradually if airplane levels off too soon. Reduce gradually if
airplane overshoots altitudes after climbs and descents. The default setting is 0.6.
Pull Rate: Use only after sensitivity and all of the above settings are set as well as they
can be. Controls the rate the AP will push or pull when changing vertical speed. The
default setting is 1.
VSI Gain: Use only after sensitivity and all of the above settings are set as well as they
can be. Increase gradually if overshooting altitude after climbs or descents, decrease if
rounding out too early. The default setting is 1.5.
G Error Gain: Use only after sensitivity and all of the above settings are set as well as
they can be. Increase gradually if vertical speed changes are not smoothed enough;
Decrease if ride is too harsh. G Error Gain adjustments affect the most noticeable
changes while the aircraft is in turbulence. The default setting is 1.
G Error Limit: Use only after sensitivity and all of the above settings are set as well as
they can be. Controls the max additional G the autopilot will push or pull to control
vertical speed (up to the G limiter). G Error Limit adjustments affect the most noticeable
changes while the aircraft is in turbulence. The default setting is 0.25.
Default Climb Vertical Speed
The default climb vertical speed parameter sets the average speed the autopilot will command
for climbs 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. If you set this parameter above a vertical
speed the aircraft can achieve, the autopilot will run into the airspeed limiter in a climb.
The default climb 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 climb vertical speed:
1. Go to the Pitch Axis Default Climb 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.
