Autopilot Servo Installation, Configuration, and CalibrationDefault Descent Vertical SpeedThe default descend vertical speed parameter sets the average speed the autopilot willcommand for descents when the pitch axis is configured in the VS:DFLT mode. You may alsocontrol the climb vertical speed with the vertical speed bug in VS:BUG mode. Reference theSkyView 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 MeasurementUnits Menu (i.e., feet per minute or meters per second; reference page 3-8 for moreinformation regarding configuring the measurement units). The default value is 500 feet perminute and the value is adjusted in 1 unit increments. The maximum value is 3,000 feet perminute.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 AirspeedIf the AP is engaged and the Maximum Airspeed limit is changed to a value that islower than the current airspeed, the AP will immediately act to reduce the airspeedto the new maximum airspeed setting, and may do so aggressively. Dynonrecommends that this setting only be adjusted with the AP disengaged.The pitch axis maximum airspeed parameter is the highest airspeed at which the pilot mayengage the autopilot. If the autopilot is engaged at the time the aircraft’s airspeed exceeds themaximum, the autopilot enters an airspeed hold mode and pitches the aircraft up to preventincreasing airspeed. SkyView simultaneously indicates that the aircraft has exceeded theparameter by displaying SPD indicators in the Top Bar and in the AP menu as illustrated inFigure 57 and Figure 58, respectively.Figure 57–Top Bar SPD IndicatorFigure 58–AP Menu SPD IndicatorsIf the aircraft’s altitude rises above the target altitude bug and the autopilot cannot pitch theaircraft down without going above the maximum airspeed, SkyView presents the prompt:REDUCE POWERThe maximum airspeed parameter cannot be set to a value above 95% of VNE, which should beset to the specifications of your aircraft in the Airspeed Limitations Menu (reference page 5-7for more information) and is specified in the units set in the Measurement Units Menu (i.e.,10-18 SkyView System Installation Guide - Revision J
