In 1998, Boeing awarded a long-term contract for the LynxOS® real-time operating system software to be used in the cabin services system aboard Boeing 777s, their newest and most technically advanced commercial jetliner.
The cabin services system automates many tasks that flight attendants previously performed manually and allows easy control of lighting, boarding music, address system and cabin doors. The cabin services system has improved the display of system faults by consolidating them on one panel, rather than on individual panels above each seat. A better response time of maintenance crews servicing the aircraft has resulted.
LynxOS' X and Motif subsystems handle the entire user interface. Boeing chose LynxOS for its support of numerous off-the-shelf devices and for its strong adherence to industry standards. Standards allow programmers to port code rapidly from other operating systems to LynxOS.
