The Autopilot Request is a normally open dry contact in the DSC. This
normally open contact closes when Autopilot control is selected through
the use of the MCP’s steering mode selector inputs described in section
2.3.1
. This dry contact output can be used by the autopilot system in
order to automatically switch the autopilot from a standby mode to the
auto mode when autopilot control is requested. Autopilot systems
normally refer to this as remote mode selection.
