Autopilot Servo Installation, Configuration, and Calibration

10-18 SkyView System Installation Guide - Revision R

SINGLE CUE (INVERTED-V): Uses a single "inverted V" symbol to indicate pitch and roll angles

that the autopilot will use to meet its goals. When the autopilot is not engaged, pitch and roll

the aircraft to align this symbol with the waterline to fly the airplane like the autopilot would.

DUAL CUE (CROSS BARS): Uses separate horizontal and vertical bars across the attitude

indicator to indicate the pitch and roll angles that the autopilot will use to meet its goals. When

the autopilot is not engaged, pitch and roll the aircraft to center both the horizontal and

vertical bars with the waterline to fly the airplane like the autopilot would.

For more details on Flight Director behavior, see the SkyView Pilot’s User Guide.

To set the Flight Director style:

1. Go to the Autopilot Flight Director Adjust Page (SETUP MENU > AUTOPILOT SETUP >

FLIGHT DIRECTOR).

2. Choose SINGLE CUE or DUAL CUE.

3. Press ACCEPT to save the value or press CANCEL to return to the Autopilot Setup Menu.

Roll Axis Configuration

Roll Axis Torque

The roll axis torque parameter specifies how much torque the servo will exert before slipping.

Servo slip is indicated by the word SLIP in black letters in a yellow box on the Top Bar for the roll

axis as shown in Figure 67.

Figure 67–Example Roll Axis Servo Slip Warning

Torque must be set high enough to prevent any slip due to air loads, but low enough that the

pilot can comfortably override the autopilot should the need arise. If the servo slips

continuously, the autopilot cannot fly the aircraft. Torque is specified in percent (%) of

maximum the servo is capable of exerting. The minimum is 10%, the maximum is 100%, and the

default value is 100%. If you can override the servo at 100% torque, use this default value.

To test roll axis servo override force:

1 2 ... 207 208 209 210 211 212 213 214 215 216 217 ... 400 401
