  1. In-flight Inerting Concepts Studied in the 2001 ARAC FTIHWG Donald R. Snow Jr. October 2001

  2. In-flight Inerting Concepts • The On-Board Design Team of the Aviation Rule-making Advisory Committee (ARAC) Fuel Tank Inerting Harmonization Working Group (FTIHWG) investigated inerting systems carried on the aircraft that operate in-flight • Other teams evaluated Ground Based Inerting (GBI) systems • Concepts included On-Board Inert Gas Generating Systems (OBIGGS) that offered full-time inerting and smaller ‘hybrid’ OBIGGS that provided flammability reduction at significantly lower cost • All of the following Figures are excerpted from the publicly-available Appendix D - On-board Inerting Design Team Report of the June 2001 FTIHWG Report Page 2
