 International Symposium on Transportation Recorders
CENTRALIZED VS DISTRIBUTED
• Distributed Recording
     Easier to Determine Pilot Actions
• Centralized Recording
     Reduces Wiring in Airplane
     Precludes Major Mod Program(s)



    International Symposium on Transportation Recorders
    DATA LINK SECURITY
• Messages Being Posted on Web
• “Scrambling” Techniques Being Studied
• Higher Security => More Complex
  Decoding
• The Key Complicates Recording Logistics
