DATA PACKAGE

• Descriptive Data
• Completely define a given design, including all
  critical equipment, parts, and attachments
• Drawings, sketches, marked-up photographs,
  process specs,
• Substantiating Data
• Shows compliance with the applicable regulations
• Basic loads analysis, structural analysis,
  electrical load analysis, test plans and reports,

6
TESTING

• Detailed parts, components and subassemblies
  produced by the developer are considered
  miscellaneous, non-required equipment and
  normally do not require testing for approval.
• Testing may be prudent to ensure equipment
  operability on the GV platform (see RTCA/DO 160D,
  Environmental Conditions and Test Procedures for
  Airborne Equipment and NSF/NCAR GV Investigators
  Handbook)
• Assembly and installation testing by NCAR may be
  required for approval (EMI/RFI, structural,
  icing,)

KEY DESIGN GUIDELINES

• Consult GV Investigators Handbook Section 5 for
  structural and electrical design criteria
• Utilize appropriate materials
• Metallic materials MMPDS 001 (Formerly
  Mil-Handbook 5H)
• Aerospace quality hardware (AN, MS, NAS, NASM)
• Genuine Aircraft Hardware Co. is a good source
  (http//www.gen-aircraft-hardware.com)
• Fasteners must incorporate some locking method
• Non-metallic materials must meet flammability
  requirements (non-flammable or self-extinguishing)
  
• Windows must be non-splintering and able to
  maintain cabin pressure after any single failure
  in the installation.
• Design within aircraft capabilities
