LYNNWOOD, Wash. – March 13, 2006 – Crane Aerospace & Electronics, a Crane
Co. segment, has been selected to supply the Onboard Tire and Brake
Monitoring System (TBMS) for the Boeing 777. The TBMS will replace the
current system on all follow-on 777 aircraft. First deliveries of
aircraft with the new system are scheduled for 2007.
The TBMS monitors the tire pressure and brake temperature of each wheel
and displays that data in the flight deck. Using Crane Aerospace &
Electronics’ new SmartStem(R) wireless technology, the system operates by
replacing the existing tire inflation valve stem with a wireless valve
stem that senses and communicates tire pressure, temperature, and other
stored information to a control unit onboard the aircraft or to a
handheld reader.
SmartStem(R) technology was designed to provide an easy, accurate method
of maintaining proper aircraft tire pressure – very important both to
aircraft safety and economics. Both the on-board and handheld versions
of SmartStem(R) make the daily tire pressure check quick, easy, accurate,
and automatically documented. A reading takes about one second.
