## Air Transport Recording Systems

- Daniel A. Martinec
- Chairman, AEEC
- Airlines Electronic Engineering Committee

*International Symposium on Transportation Recorders*

## TOPICS

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

## 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

## AEEC COMPOSITION

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

## 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

## 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..)

## ARINC STANDARDS (OLD)

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

## 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)

## 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

## 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

## ARINC 767 SYSTEM 

- 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

## ARINC 767 SYSTEM (more!!)

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

## DATA LINK RECORDING ISSUES

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

## DISTRIBUTED RECORDING

## CENTRALIZED RECORDING

## CENTRALIZED VS DISTRIBUTED

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

## DATA LINK SECURITY

- Messages Being Posted on Web
- “Scrambling” Techniques Being Studied
- Higher Security => More Complex Decoding
- The Key Complicates Recording Logistics

## ADDING SECURITY

## AEEC PLAN/ SCHEDULE 

- AEEC PLAN/ SCHEDULE

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

## CONCLUSION 

- CONCLUSION

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