Autopilot Servo Installation, Configuration, and CalibrationDefault Descent Vertical Speed (Simplified Controls Only)This setting only applies to simplified autopilot controls. The default descent vertical speedparameter sets the initial vertical speed the autopilot will command for descents when analtitude change is requested. You may also control the descent vertical speed after a descent isin progress with the vertical speed bug. If you set this parameter below the vertical speed theaircraft can achieve, the autopilot will run into the airspeed limiter during descent.The default descent 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.To adjust the default descent vertical speed:1. Go to the Pitch Axis Default Descent Vertical Speed Adjust Page (SETUP MENU >AUTOPILOT SETUP > PITCH AXIS > DEFAULT DESCENT VERTICAL SPEED).2. Adjust the default descent vertical speed.3. Press ACCEPT to save the value or press CANCEL to return to the Pitch 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 as illustrated in Figure 66.Figure 66–Top Bar SPD IndicatorIf 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:Figure 67 - Top Bar Airspeed High IndicationThe 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 5-6for 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 information10-18 SkyView System Installation Guide - Revision O
