PressureGasDumpManifold - RAF Instruments

Operational Status (select from or add to list):
- requestable, ready for deployment
General Description (with photos, diagrams, etc.):
Long rigid tubes 5 cm dia are installed on left and right sides of the fuselage cabin. These tubes have collection fittings at several locations where air sample instruments can vent their exhaust. The tubes vent to the belly of the aircraft and have a skarf tube cut that provides a pressure reduction. Pressure sensors are located near the vent locations.
Measurement Characteristics:
- Overall estimate of uncertainty: <1% fs
- Response time: 1 sec
- Precision:
- Other measurement characteristics (comments on signal/noise, bias limits, etc):

Description of Software, Data Handling, and Data Flow:
- Software Components (data acquisition, display, processing, and analysis):
- Data Processing Chain (from flight to archival): Data processing follows the standard data path for RAF measurements: instrument -> NIDAS -> nimbus -> netCDF archives. See this page for more information.
QA Procedures and Needs: expect PDump varies with altitude and is about 50 mb less than ambient pressure
