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

ICD changesICD title SOFIA doc A.K.A Description Changes

SI Handling Cart to Aircraft System

SOF-AR-ICD-SE03-205 (Rev. B)

SIC_AS_01 Cart to aircraft 1st 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-SE03-2017 (Rev. A)

SIC_SSMO Cart to hangar Minor, Carts must be either forklift-able OR able to navigate lift truck gate ramp lip.

Science Instrument Equipment to Counterweight Rack

SCI-AR-ICD-SE03-2027 (Rev. A)

SI_CWR_01 Instrument to CW rack

Minor Measurement changes (still std 19 in rack spacing) ; Formatting

PI Patch Panel to PI Equipment Rack(s)

SOF-AR-ICD-SE03-2029 (Rev -)

SI Equipment Rack / TA Counterweight Interface

SOF-AR-ICD-SE03-051 (Rev. 1)

TA_SI_05 CW rack to TA Minor changes, formatting

PI Equipment to PI Rack to Aircraft System

SOF-DF-ICD-SE03-2015 (draft A) [PCB next week]

SI_AS_01 PI rack ICD Minor measurement changes (still std 19 in rack sizing) ; formatting

SI handling cart to science Instruments

Deleted SIC_SI_01 Cart to Instrument Deleted; dates back to when SOFIA was providing a cart to the instruments
