1 Science Instrument Requirements Document Reorganization Scott Horner SITR – 19 February 2010

2 SOFIA Spec Tree (SOF-DF-SPE-SE Rev. D)

3 The Experimenter’s Handbook was not written as a specification The Problem These child documents don’t exist

4 SOFIA Spec Tree (SOF-DF-SPE-SE Rev. D) Science Instrument System Specification SOF-AR-SPE-SE

5 The reorganization ICP Guidelines (USRA-DAL- SSMOC-SCIN- PLAN-4100) Experiment Developers Handbook (OP03-001) Science Instrument System Specification (SOF-AR-SPE-SE ) Instrument Developers Handbook (SCI-AR-HBK-OP ) Observer’s Handbook () Was: Is: SI System Spec – Will contain requirements (shall statements) for SI instruments, including performance, airworthiness, and quality assurance. It will also reference the ICDs applicable to the science instruments. Instrument Developer’s Handbook – Will be a narrative guide describing how an instrument is developed, discussing the documents to be delivered and the reviews that will be held. Observer’s Handbook – Will be a narrative guide describing how to apply for and use observing time on SOFIA. More details can be found in “Experimenter’s Handbook restructuring” memo to be issued shortly

6 ICD changes ICD titleSOFIA docA.K.ADescriptionChanges SI Handling Cart to Aircraft System SOF-AR-ICD-SE (Rev. B) SIC_AS_01Cart to aircraft1 st gen carts use old requirements swiveling caster requirements. Will construct and distribute solid model of 1L door and entryway. Wheel loading requirement altered to specify maximum pressure, not weight. SI Handling Cart to SSMO Facility SCI-AR-ICD-SE (Rev. A) SIC_SSMOCart to hangarMinor, Carts must be either forklift-able OR able to navigate lift truck gate ramp lip. Science Instrument Equipment to Counterweight Rack SCI-AR-ICD-SE (Rev. A) SI_CWR_01Instrument to CW rack Minor Measurement changes (still std 19 in rack spacing) ; Formatting PI Patch Panel to PI Equipment Rack(s) SOF-AR-ICD-SE (Rev -) MCCS_SI_05PI patch panel to SICombined MCCS_SI_02 and MCCS_SI_03 into MCCS_SI_05; Measured power now reported SI Equipment Rack / TA Counterweight Interface SOF-AR-ICD-SE (Rev. 1) TA_SI_05CW rack to TAMinor changes, formatting PI Equipment to PI Rack to Aircraft System SOF-DF-ICD-SE (draft A) [PCB next week] SI_AS_01PI rack ICDMinor measurement changes (still std 19 in rack sizing) ; formatting SI handling cart to science Instruments DeletedSIC_SI_01Cart to InstrumentDeleted; dates back to when SOFIA was providing a cart to the instruments
