Sync System Overview

The Scott Plot® Sync System currently allows a maximum of two iPads to be connected simultaneously for sharing plotting information during a flight. One of the iPads is designated as the Primary by the crew, responsible for oceanic plotting. The data entered on the Primary iPad is shared in real time with the Secondary iPad, which the other crew member operates. Both crew members can perform oceanic plotting tasks, and the Sync System automatically synchronizes the plotting information between the connected iPads. For longer trips with additional crew members, the pilots can switch between the Primary role or swap roles between devices to facilitate crew rotation.

The Two Sync Roles

  • Primary role iPad — intended for the crewmember and iPad primarily responsible for all oceanic plotting tasks with Scott Plot. The Primary role iPad will always send a complete update of plotting information to a Secondary role iPad upon initial and subsequent sync connections. The Primary iPad data will always overwrite the Secondary iPad data upon those initial sync connections and reconnections. The Primary role iPad is the main source of data.
  • Secondary role iPad — intended for an additional crewmember iPad; allows real-time viewing of plotting updates made by the Primary role. The Secondary role also has full access to oceanic plotting activities (flight plan and chart annotations, 10 min checks, wind correction stamps, route changes, position reports, various note fields, and all Journey Logbook entries). Plotting updates automatically synchronize between the Primary and Secondary iPads during a sync-connected flight.

The crewmember who has loaded the flight documents onto their iPad and completed the Preflight Wizard steps should select the Primary role to send over all trip information to the other crewmember, who sets Secondary as their role. In case of an inadvertent overwrite of Secondary data, see the restore functionality on the Sync System controller.

Note: The information from the Primary role will always overwrite any information on the Secondary role iPad upon initial sync connection or reconnections.
