C-17 Pitot Static Breakout Box (PSBB)

The C-17 Pitot Static Breakout Box is a derivative of TestVonics™ Line Switching Unit (LSU) Series. The assembly includes a multi-port distribution unit which provides 4 Pitot and 8 Static outputs from one channel of Pitot and Static controlled pressure. The LSU distributes pitot static supplies for the external services and connection of hose assemblies for testing of aircraft Pitot and Static ports for the C-17. The lightweight unit is housed in a highly durable and easy to maneuver case. Additionally, four (4) 30ft Pitot Hoses, eight (8) 30ft Static hoses, and two hose storage bags are included with the assembly.

TestVonics TVCS-LSU-C17 Pitot Static Breakout Box (PSBB) for the C-17 can significantly enhance operation of any manufacturer’s Air Data or Pitot Static Test Sets. The PSBB, also approved under Boeing P/N: 17G573809-1, is designed for use with the C-17 aircraft, but it can be used to support other aircraft as well. The panel features color coded manual On/Off shutoff valves to connect the air data test system to Captain, First Officer and Auxiliary pitot-static systems (or other) at the same time. The LSU can save test time for performing multiple system air data tests. This increases aircraft availability and reduces testing time, which reduces costs. Each of the Pitot and Static outputs can be fully isolated to allow independent system testing, which is often required.

The front panel features either four (4) or six (6) outputs. On/Off valves allow for ease of use and the operator can quickly identify if an output is open or closed. All outputs feature color coded shutoff valves and dust caps. The LSU does not require any power to operate and it is housed in rugged lightweight case with retractable handle and wheels for ease of transport.
