Abstract

Passenger Information Sign is a system that consists of a no-smoking sign, return to seat, fasten seat belt sign, which serves as a support for safety aspects when bad weather occurs where all passengers must remain in their seats and must use safety belts and during critical eleven due on board, all of passengers must be ensured in their seats with safe conditions. The method used in solving problems involving the Passenger information sign system by troubleshooting is based on the AMM Boeing 777-200/300, starting from examining the passenger information sign components, namely: (1) CSMU or Cabin System Management Unit which gets input from ARINC 629 and ARINC 628 and in the aircraft cabin is divided into three zones where CSMU provides output to, (2) ZMU or Zone Management Unit which functions to foster passenger compartment lights in each zone, forwarded to, (3) OEU or Overhead Electronics Unit which provides power for Passenger information signs on each seat and the OEU receives output from the PCU or Passenger Control Unit to give reading light assistance or call attendant commands. Cabin compartment light, especially in the Passenger information sign where no-smoking does not comes on in zone one when an operational check is carried out. We can identify the problem in the ZMU where this component functions as a controller for each zone. After the problem is found in the ZMU, and the ZMU installation is done, after the installation process is complete, it must be followed by testing on the info sign system and the no-smoking sign can be operate normally Keywords : CSMU(cabin service management unit), ZMU(zone management unit), OEU(overhead electronics unit).
