Remote slave display

The RB-09 is a fully slave display: it reads no sensors of its own and shows the remote data sent to it. Its form factors and components are the same as the RB-02, in the 80mm and 57mm round formats.

Connected to RB-Simulator, the RB-09 becomes an instrument of your Flight Simulator 2020 cockpit, showing the attitude and air data of the simulated aircraft. A single RB-Simulator can drive several RB-09 displays.

RB-Simulator sends the flight data from Flight Simulator 2020 to an RB-01 and two RB-09 displays Flight Simulator 2020 RB-Simulator RB-09 RB-01 RB-09

  • Flight Simulator 2020
  • Multiple devices

Flight Simulator connector

RB-Simulator is the connector that turns RB-Avionics instruments into the cockpit of Microsoft Flight Simulator 2020. Enabled in Flight Simulator 2020, it sends the data of the simulated flight to the RB-01 remote unit and to the RB-09 displays.

  • Connector for Microsoft Flight Simulator 2020
  • Sends the simulator data to the RB-01 remote unit
  • Drives RB-09 remote slave displays
  • Drives multiple devices at the same time

Use your RB panel in a home cockpit, or rehearse your aircraft's avionics on the ground. For simulator use only: RB-Simulator is not an approved flight simulation training device, and time on it is not loggable training.
