ADS-71-SP, AERONAUTICAL DESIGN STANDARD STANDARD PRACTICE: ENVIRONMENTAL AIRWORTHINESS AND QUALIFICATION REQUIREMENTS FOR ELECTRONICS, AVIONICS, AND MISSION EQUIPMENT INSTALLED ON ARMY AIRCRAFT (07 OCT 2009)

ADS-71-SP, AERONAUTICAL DESIGN STANDARD STANDARD PRACTICE: ENVIRONMENTAL AIRWORTHINESS AND QUALIFICATION REQUIREMENTS FOR ELECTRONICS, AVIONICS, AND MISSION EQUIPMENT INSTALLED ON ARMY AIRCRAFT (07 OCT 2009)., This ADS establishes the requirements and verification processes through which airworthiness and environmental qualification of avionics, electronics, or other related mission equipment is accomplished. This Aeronautical Design Standard (ADS) applies to all new and/or modified avionics, electronics, and mission equipment installed or affiliated with Army aircraft and contains the environmental test requirements for satisfying the various phases of airworthiness from Safety of Flight (SOF) through full qualification. The operational requirements for Army aircraft components ultimately originate from the eser who specifies the performance criteria. Frequently included in these performance criteria is the ability of the component to operate within its design specifications under specific induced and natural environments. For optimum results, a Life Cycle Environmental Profile (LCEP) should be generated by the combat/materiel developer to define the most extreme environmental stressors or combination of environmental stressors that a component will be exposed to during its service life. The LCEP supports the User specified performance criteria thereby influencing the design and test phases of the component developmental process. MIL· STD-810, Task 402 (Life Cycle Environmental Profile (LCEP)) explains this process in detail. After the engineering design phase of the component LCEP has been completed, the component is subjected to specific environmental testing to verify the design satisfies the intended performance and airworthiness/qualification requirements as defined in AR-70-62. The primary goal of this ADS is the definition of environmental requirements. Among qualification methodologies, the preferred is testing, but other methods such as similarity or analysis are also accepted.
