PFPD PRINCIPALS COMPLIANCE

• Design Principles compliance assessment
• Compliance exception due to Spacecraft/Mission
  Design
• 3.3.1 Continuous Telecommunications Capability
  during Events
• Fixed design of the spacecraft means that the
  bank turn during flyby could cause loss of comm.
  In the Mission Plan does not impact prime
  science
• 9.3.1 Powering off the RF downlink
• Insufficient solar power beyond 2 AU for
  continuous operation
• Possible risk of db loss due to continuous SSPA
  operation
• Flight Project Practices compliance assessment
• Three potential non-compliances, related to
  Discovery class small organization
• 5.4.2 Organizational positions
• 5..9.3.3 Earned value not used in Phase E
• 7.8.5 No Project Safety Steering committee
