Title: Integrated Part 23 Cockpit Displays

Integrated Part 23 Cockpit Displays
FAA Small Airplane Directorate Aircraft

  • Wes Ryan
  • 816-329-4127
  • Dec, 2004

  • 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
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
  • Guidance frequently plays catch-up. First
    approval helps generate new guidance
  • Lessons learned, but some areas still need
    clarification - GPS, Displays, Wiring

  • 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?

  • 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
  • AC 23-17B Systems and equipment (public
  • New Guidance
  • AC 23-21 Checklist for major alterations
  • 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 doesnt take
  • 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 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

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

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
  • 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
