________________________________________________________
1.
General
_______ The Passenger Visual Information System (PVIS) supplies the passengers with information on ambient aircraft flight data, times and aircraft position in the flight plan. The PVIS uses the Liquid Crystal Display (LCD) monitors and other main components of the Passenger Entertainment System (PES) (Video) to show the information on screen.

3. System Description
__________________ The PVIS uses the PES (video) to transmit its output data to the passenger as visual information.
A. System Integration The system receives its operational input data from the Aircraft Communication Addressing and Reporting System (ACARS), the Air Data/Inertial Reference System (ADIRS), the Centralized Fault Display System (CFDS) and the Flight Management and Guidance System (FMGS). The PVIS is made up of the subsequent main components:
-
a Remote Control Unit (RCU)
-
a Digital Interface Unit (DIU).
The RCU is installed in the video control center in the most forward of the LH overhead stowage compartments. It is the input unit on which the shown information is selected by the use of menus.
The DIU is the system computer. It is installed on the electronics rack 88VU in the rear of the electronics compartment. The DIU stores the program menus, and it receives the input data from the above named systems. It processes them for use with the stored menus. It then transforms the digital data into video signals and sends them to the PES (video) for their indication on the LCD monitors.
