If yes is selected, then the MFD restarts using the same source groups as the AP70/AP80
system. If No is selected then the question is not asked again and the MFD cannot be used to
operate the AP70/AP80 system.
This setting can be changed by selecting Professional autopilot compatibility in the
Advanced settings dialog. When this option is ticked ON, the MFD can be used to operate
the AP70/AP80 system.
Running thruster symbols
When thrusters are running in an AP70/AP80 system, red and green arrows are displayed in
the MFD Autopilot controller to indicate thrust direction.
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 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 Autopilot controller:
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.
Locked system - The key icon indicates it can be a Master system or a
locked Open system.
