TOPICS

• ARINC/AEEC Composition/Function
• Current ARINC Standards
• Status of Work Program
• Goals for Future

3
WHO IS AEEC?

• Formed in 1949 by ARINC Board
• Falls under ARINC Board supervision
• Composed of Airlines, Aviation
  Associations and USAF
• Supported by Avionics Users and Suppliers
• All Technical Meetings Open to Public

4
AEEC COMPOSITION

• Eleven North American Airlines
• Six European Airlines
• Orient Airlines Association
• IATA , ATA and NBAA
• USAF
• Participation from 7000 From Industry

5
BASIC AEEC FUNCTIONS

• Prepares Avionics Standards to Promote
  Competition
• Improves Reliability by Marketplace Pressures
• Assists in Concurrent Avionics/Airplane Design
• Promotes Safety Enhanced Federal Regulations
• Promotes More Effective Certification Procedures

6
COOPERATION IS CRUCIAL

• RTCA/EUROCAE
• International Civil Aviation Organization)
• IEEE
• Society of Automotive Engineers (SAE)
• EIA/ANSI/ISO Standards Organizations
• Regulatory Agencies (FAA, CAA, etc..)

7
ARINC STANDARDS (OLD)

• ARINC 542 - Oscillographic Recorder (Obs)
• ARINC 542A - Digital Flight Data Recorder
• ARINC 557 - Cockpit Voice Recorder
• ARINC 573 - Airborne Recording System

8
ARINC STANDARDS (NEW)

• ARINC 717 Digital Flight Data Acquisition Unit
• ARINC 747 Flight Data Recorder
• ARINC 757 Cockpit Voice Recorder
• ARINC 757-1 Combined Voice/Data Recorder
• ARINC 767 Advanced Recording System
• (In Development)

9
ARINC 747 DATA RECORDER

• Accommodates Solid-State Memory
• Replacement for ARINC 573 FDR
• Compatible with 573/717 Acquisition Units
• Expandable for Larger Recording Capacity
• Standard is Stable at This Time

10
ARINC 757 AND 757-1 CVR

• Accommodates Solid-State Memory
• Replacement for ARINC 557 CVR
• 757-1 Added Data Recording Function to 757
• Includes Physical Interface for Data Link
• Protocol for Data Link Recording Incomplete

11
ARINC 767 SYSTEM

• All-New System for Future Airplanes
• Solid-State Memory
• New High-Speed DFDAU/DFDR Interface
• High-Capacity for Data Recording
• 2-Hour Voice/Data Link Recording

12
ARINC 767 SYSTEM (more!!)

• Direct Digitized Voice Recording
• Video Recording Capability
• Forward and Aft Installations
• 10-Minute Reserve Power for Voice

13
DATA LINK RECORDING ISSUES

• Central vs. Distributed Recording Points
• Security of Data Link Communications

14
DISTRIBUTED RECORDING
15
CENTRALIZED RECORDING
16
CENTRALIZED VS DISTRIBUTED

• Distributed Recording
• Easier to Determine Pilot Actions
• Centralized Recording
• Reduces Wiring in Airplane
• Precludes Major Mod Program(s)

17
DATA LINK SECURITY

• Messages Being Posted on Web
• Scrambling Techniques Being Studied
• Higher Security gt More Complex Decoding
• The Key Complicates Recording Logistics

18
ADDING SECURITY
19
AEEC PLAN/ SCHEDULE

• Resolve Data Link Issues - End of 1999
• Update ARINC 757 - Spring 2000
• Completion of ARINC 767 - End of 2000

20
CONCLUSION

• AEEC GOALS
• Improve Safety By Enhanced Recorders
• Reduce Costs With More Reliable Units
• Employ Optimum Design Techniques
