Autopilot Servo Installation, Configuration, and Calibration

10-22 SkyView System Installation Guide - Revision R

The minimum airspeed parameter must be set to at least (and defaults to) 30% above VS1,

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 previously mentioned, the

minimum value for this parameter is 30% above VS1. This is also the default value.

To set the minimum airspeed:

1. Go to the Pitch Axis Minimum Airspeed Adjust Page (SETUP MENU > AUTOPILOT SETUP

> PITCH AXIS > MINIMUM AIRSPEED).

2. Adjust the minimum airspeed.

3. Press ACCEPT to save the value or press CANCEL to return to the Roll Axis Menu.

Disengage Button Options

Hold to Engage

Hold to Engage may be set to YES or NO. Setting HOLD TO ENGAGE to YES allows you to engage

the autopilot by holding the Disengage/CWS Button for more than 2 seconds. This allows for a

convenient alternative to engaging the autopilot via the AUTOPILOT Menu.

When HOLD TO ENGAGE is set to YES, anytime the autopilot is disengaged you can engage it by

pressing and holding the Disengage/CWS Button for more than 2 seconds. Note that after 2

seconds, the autopilot status indicator in the Top Bar on the SkyView REL TO ENG (release to

engage), as illustrated in Figure 72.

Figure 72–Autopilot Hold to Engage Mode

This indicates that the servos are in hold to engage mode and are waiting for the button to be

released before engaging.

To set the hold to engage mode:

1. Go to the Hold to Engage Adjust Page (SETUP MENU > AUTOPILOT SETUP > DISENGAGE

BUTTON > HOLD TO ENGAGE).

2. Set to YES or NO.

3. Press ACCEPT to save or press CANCEL to return to the Disengage Button Menu.

Enable Broken Line Detect

The ENABLE BROKEN LINE DETECT option may be set to YES or NO. It should only be set to YES if

the optional 5 kΩ resistor is installed across the Disengage/CWS Button, as shown in Figure 63.

If the resistor is installed and this option is set to YES, SkyView continuously monitors the AP

Disengage/CWS Button circuit for proper resistance. If a broken line is detected, SkyView will

display the following message:

AP BROKEN DISCONNECT
