Command transfer
An AP70/AP80 system can be set up as a Master system or an Open system.
In a Master setup, the master controller gives control to other control units. An MFD cannot
be the master controller in a Master setup. In a Master setup, the MFD can request to control
the autopilot and the MFD must accept control from the master controller after the master
controller approves transfer of control to the MFD. Once control is accepted, the MFD is
active and can be used to operate the autopilot.
In an Open system setup, the MFD can take control of the autopilot by selecting the Mode
button on the Autopilot controller pop-up and then selecting Take cmd in the CMD transfer
dialog. When this occurs the MFD becomes active and the other control units become
passive.
In an Open system, control stations can be temporarily locked to avoid accidental control
from another control unit. When the MFD has control in an Open system, the MFD can lock
and unlock all passive control units. If the MFD is passive and locked, it can request control of
the autopilot from the active control unit. The MFD must accept control from the active
controller after the active controller approves transfer of control to the MFD.
The following indicators are displayed in the Mode button of the Autopilot controller pop-
up:
Passive - MFD does not have control of the autopilot. If only the passive
icon is displayed, it means it is an Open unlocked system and selecting
the Mode button takes control of the autopilot.
