5. V5 Requirements Verification
In addition to L4 instrument requirements (above) requirements flow from mission documents
FIELDS ICD
GI ICD
EMECP
EDTRD
QA Matrix
Tracked at higher levels of assembly

6. Instrument I&T Plans Philosophy Tests on ETU and then Flight Units
Requirements are verified as early as possible at a low level
Verifies subsystems, Retires risk
Requirements are verified at the highest level of assembly possible
Often involves verifying a requirement at several levels
Maintain flexibility in test sequencing to maintain schedule
Tests on ETU and then Flight Units
Subset of tests on ETU to qualify the design where practical and possible
Some complete – some continue to 1 March 2015
Full tests on Flight units
Typical Test Levels:
Subassembly (circuit board): functional
Component (e.g. V1, MAG, SCM, MEP, V5): functional, mass properties, vibration, TV, deployments, magnetics
Instrument: functional, comprehensive, calibration, interface, EMC, TV

7. Environmental Test Matrix

8. Planned FM I&T Flow

9. Validation All instrument requirements are captured in IRD
IRD contains columns detailing how and where the requirement is met
IRD doubles as verification cross reference matrix
Systems Engineer is responsible for verifying test procedures meet requirements and responsible for verifying that all requirements are met by following test plan
