NASA Langley Research Center, ISAAC Project

HS Advanced Concepts LLC supported the NASA Langley Research Center’s Systems Analysis Group under the sponsorship of an Integrated Systems Analysis and Assessment Capability (ISAAC) project with a task “Initial Assessment of Aircraft Certification Procedures for Emerging Technologies“. The objective was to identify gaps that may exist due to emerging technologies in both new certification rules and existing standards used as means of compliance to these rules for Normal Category Aircraft. There were three tasks:

  • Certification Basis Review

  • Evaluation of NASA Activities Relevant to Certification Gaps

  • NASA-Regulator-Standards Body Coordination
