Overview GA in Transition Standardization –Lessons Learned - GPS –Better Guidance –Cockpit Standardization –AML process –Wiring New technology & Coordination

GA in Transition Finally transitioning to new technology 40+ yrs old New

GA 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

GA in Transition - Technology 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

Standardization Lessons Learned – First Generation GPS Questions 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?

Standardization Better Guidance Provide 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 - GPS Guidance - AC A 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

Standardization - Guidance Changes to Existing Guidance AC B – Electronic Displays (public comment) AC 23-17B – Systems and equipment (public comment) New Guidance AC – Checklist for major alterations (final) AC – Approved Model List (AML) (public comment closed in November) AC – Integrated cockpits (final)

Standardization - Cockpits GAMA Pub 12 - Cockpit Standardization Industry and FAA participation Expands on AC , but doesn’t take precedence Meant to streamline certification States acceptable minimum standard Make glass-to-glass transition easier AC references as acceptable means

Standardization - AML Draft AC for Approved Model List Defines 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

Standardization - Wiring A Part 23 Policy Flammability memo has been released Internal Stop–gap to let everyone know that AC 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 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 Plans Policy on AFM revisions –FAR Streamlining process for Recips < 6000 lbs AC Common STC checklists –Similar to AC for major alterations –Ensures completeness of data for common modifications. –“Level the playing field” and clarify issues

New Technology - Synthetic & Enhanced Vision Sensor or Database Image Synthetic Vision - Chelton already certified - Generating policy Enhanced Vision – “SA” only is not enough – Define intended function – Generating policy

New 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?

New Technology – Airborne Surveillance Infrared and Visible Spectrum Lasers UAVs
