GA in Transition – AccidentsGA in Transition – Accidents
We hope to reduce the accident rate by providing better information to the pilot.
Currently average 1 fatal accident a day Accident rate/numbers relatively flat CFIT and LOC are still primary concern Seek to reduce fatal GA accident rate Safer skies proposed use of technology Reducing pilot workload is paramount

Change is always a challenge
May improve situational awareness and reduce pilot workload – but can the average pilot use it?
Guidance frequently plays catch-up. First approval helps generate new guidance
Lessons learned, but some areas still need clarification - GPS, Displays, Wiring
StandardizationStandardization
Lessons Learned – First Generation GPSQuestions regarding design approval,
installation approval, and operations
Non-standardization of functionality - Challenges for rental pilot & training
Coordination & Guidance could be better
Field approvals & follow on approvals, when are they appropriate?
StandardizationStandardization
Better GuidanceProvide clearer and more timely guidance –
incorporate lessons learned
Streamline installation approval for part 23 avionics and improve the level of safety
Streamlining is not an excuse to “lower the bar”
Goal to get safety enhancing technologies to existing fleet to reduce accidents
Standardization - GPSStandardization - GPS
Guidance - AC 20-138A Incorporates lessons learned + Clarifies
installation requirements
- GPS no longer “new technology”
- Not all GPS installation treated as minor alterations – this needs clarification
- Working on clarification with Flight Standards for AFM supplement issues

Changes to Existing Guidance
AC 23.1311-1B – Electronic Displays (public comment)
AC 23-17B – Systems and equipment (public comment)
New Guidance
AC 23-21 – Checklist for major alterations (final)
AC 23-22 – Approved Model List (AML) (public comment closed in November)
AC 23-23 – Integrated cockpits (final)
Standardization - CockpitsStandardization - Cockpits
GAMA Pub 12 - Cockpit Standardization Industry and FAA participationExpands on AC 23.1311, but doesn’t take
precedenceMeant to streamline certificationStates acceptable minimum standardMake glass-to-glass transition easierAC 23-23 references as acceptable means
Standardization - AMLStandardization - AML
Draft AC 23-22 for Approved Model ListDefines formal process requirements
Not an excuse to lower the bar
Best suited for simple installations
Prototyping approach for complex systems
Further showing of compliance probably needed for complex systems

A Part 23 Policy
• Flammability memo has been released
• Internal Stop–gap to let everyone know that AC 43-13 is still useful – still in works
• Ties wiring detail to cert basis of airplane being modified – need to add wire marking info
ASTM F39 Consensus Standard
• Industry and FAA to generate a detailed part 23 “best practices” wiring manual
• Include flammability policy concepts
FAA & TCCA CoordinationFAA & TCCA Coordination
Coordination meeting held - Oct 5-6, 2004• Your concerns are similar to ours – we
have agreed to work together to solve them
• Future coordination is a must for new technology and guidance efforts
• Informal communication when issues come up will help
Standardization – Future PlansStandardization – Future Plans
Policy on AFM revisions
– FAR 23.1581
• Streamlining process for Recips < 6000 lbs
AC 23-24 - Common STC checklists
– Similar to AC 23-21 for major alterations
– Ensures completeness of data for common modifications.
– “Level the playing field” and clarify issues
New Technology - Synthetic & New Technology - Synthetic & Enhanced VisionEnhanced Vision

Enhanced Vision
– “SA” only is not enough
– Define intended function

New Technology – MEMS AHRSNew Technology – MEMS AHRS
Digital AHRS Sensors Quality of Sensors Varies
- Drift rate
- Reliability
Integration of Systems Varies
– GPS, ADC, AHRS Systems no longer federated
– External data
– Failure Modes
– New TSO needed for digital AHRS?
