GA in Transition

• Finally transitioning to new technology

New
40 yrs old
4
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

5
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

6
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?

7
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

8
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

9
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)

10
Standardization - Cockpits

• GAMA Pub 12 - Cockpit Standardization
• Industry and FAA participation
• Expands on AC 23.1311, but doesnt take
  precedence
• Meant to streamline certification
• States acceptable minimum standard
• Make glass-to-glass transition easier
• AC 23-23 references as acceptable means

11
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

12
Standardization - Wiring

• A Part 23 Policy
• Flammability memo has been released
• Internal Stopgap 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

13
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

14
Standardization Future Plans

• Policy on AFM revisions
• FAR 23.1581
• Streamlining process for Recips lt 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

15
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

16
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?

17
New Technology Airborne Surveillance

• Infrared and Visible Spectrum Lasers
• UAVs
