  1. INSTRUMENTATIONDESIGN ANDAPPROVAL HAIS Developers’ Workshop HAIS Workshop

  2. REQUIREMENTS • Regulatory • Title 14 CFR Part 21, Certification • Title 14 CFR Part 25, Airworthiness Standards • Title 14 CFR Part 43, Maintenance,…and Alteration • Title 14 CFR Part 91, General Ops and Flight Rules • Guidance • AC 21-40, STC Application Guide • AC 25-10, Non-required Equipment installation • AC 43-13, Acceptable Methods- Aircraft Alterations • AC 43-210, Field Approval Procedures • NSF/NCAR GV Investigator’s Handbook HAIS Workshop

  3. APPROVAL PROCESS • Research • Plan and determine eligibility • Submit Data Package • Descriptive and substantiating data • Inspection and Test • Detailed parts, components, and subassemblies • Perform Alteration / Installation • Inspection and Test • Assembly, modification and installation • Flight Clearance HAIS Workshop

  4. PRIMARY RESPONSIBILITY • Research Developer & NCAR • Submit Data Package Developer • Inspection and Test Developer • Perform Alteration NCAR • Inspection and Test NCAR • Flight Clearance NCAR HAIS Workshop

  5. 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,… HAIS Workshop

  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 Investigator’s Handbook) • Assembly and installation testing by NCAR may be required for approval (EMI/RFI, structural, icing,…) HAIS Workshop

  7. KEY DESIGN GUIDELINES • Consult GV Investigator’s 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 HAIS Workshop

  8. LOADS • Ultimate vertical loads factors: • Forward fuselage (GVFS44.5-GVFS229) 6.0g • Mid fuselage (GVFS229-GVFS632) 6.43g • Aft fuselage (GVFS632-GVFS758) 7.0g • Tail compartment (GVFS758-GVFS956) 8.12g • BL193 wing store 6.23g • Vertical tail deck 8.9g and BL123 and BL264 wing store • Design pressures • Max emergency relief valve pressure: 10.48 psi • Design limit pressure: 1.67 x 10.48 = 17.50 psi • Design ultimate pressure: 1.50 x 17.50 = 26.25 psi HAIS Workshop

  9. EXTERIOR CAPABILITIES • Apertures • External equipment: Wtmax = 50 lbs, Af = 54 sq in, hcg = 12 in • Internal equipment: Wtmax = 25 lbs, V = 16x16x8 in, hcg = 8 in • Optical Ports • Optical units: Wtmax = 90 lbs • External equipment at aft, lower: Wtmax = 36 lbs, Af = 64 sq in, hcg = 10 in • Window Blanks • Equipment: Ø2 in, Mmax = 600 in-lbs • Wing Hard-points • BL193: Ø20 in, L = 13.3 ft, Wtmax = 1500 lbs • BL123 and BL264 : 2 PMS style probes per hardpoint HAIS Workshop
