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 New 40+ yrs old
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 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
Standardization - Guidance 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 - Cockpits GAMA Pub 12 - Cockpit Standardization • Industry and FAA participation • Expands on AC 23.1311, but doesn’t take precedence • Meant to streamline certification • States acceptable minimum standard • Make glass-to-glass transition easier • AC 23-23 references as acceptable means
Standardization - AML Draft AC 23-22 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 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 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 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 & 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
