3.3.1.1.7 Autopilot Test
The AUTOPILOT TEST page allows testing of the roll steering interface (if installed) to the autopilot by
allowing specific roll steering commands to be set. While on the TEST menu page, press the
AUTOPILOT TEST line select key to display the AUTOPILOT TEST page. The AUTOPILOT TEST
page is shown in Figure 3-26.
Turn the large, outer knob to select the parameter to be edited. The currently selected parameter is shown
with a white background. Turn the small, inner knob to change the value of the selected parameter. The
roll steering parameter can be set from 30° left to 30° right in one-degree increments. The ground speed
can be set from 0 kts to 1000 kts in five-knot increments.
Some autopilots or roll-steering converters require ground speed, while others do not.
Because of this the capability to set the ground speed using the small, inner knob has
also been provided, although it will not be required for all autopilots.
For installations with roll steering, engage the autopilot in GPSS mode and verify that GPSS is valid via
the autopilot indication. Vary the roll/steer value left and right and verify that the autopilot behaves
accordingly.
Press the TEST or BACK smart key to return to the Ground Maintenance Test menu.
