The Time is Right

• SMS rising• Precursors to

accidents / incidents• Risk reduction &

prevention• Data mining / analysis


Framework for Safety Data Sharing

Collaborative and voluntary adoption of solutions and best practices

Benchmarks and Metrics


Key Aviation Safety Data Elements


Digital Aircraft Data: FOQA and FDM

• Passive acquisition and archiving of aircraft operations

• Hundreds of flight parameters

• Objective measurements

• Recording of exceedances and atypicalities


Voluntary Safety ReportsAir Traffic Controllers

Maintenance Technicians

Pilots

Flight Attendants

Dispatch


Airport Safety Data• Ramp incidents data• Runway/taxiway

closures and modifications

• Surface conditions• Airport elevation

Data• Obstacle data• Terrain information


Air Navigation Service Provider (ANSP) Operational Data

• Emerging power of operational data derived from air traffic control systems

• Airspace and procedure data

• Radar and Surveillance data

• Weather and wind data• Different domains: En

Route, Aerodrome, Tower


Fatigue and Biometric Data in Aviation

PilotAir Traffic Controllers Maintenance technicians

• Need for Fatigue Risk Management best practices

• Need to develop metrics and measure FRM

• Need to integrate FRM into Safety Management Systems


Emerging Opportunity:Mining of Air-Ground Voice Data

Some Emerging Issues


• Data acquisition, archiving & management

• Cloud computing• Data quality assurance• Data mining capabilities• Metrics development • Robust algorithms• Visualization techniques

Improving Data Quality and Analysis Capabilities


• Fostering Voluntary safety reporting

• Data protection and sharing

• Data fusion• Data aggregation• Risk reduction and

mitigation

Effective Governance


World-Wide Harmonization• Cultural norms relating

to safety reporting• Standards & guidance• Taxonomy • Scalability• Reporting & analysis

Capabilities• Outreach and

Education


The Way ForwardHow do we Get there from here?

• The time is right• Facilitating World-wide

community information sharing

• Need focus World-wide community efforts in a common direction

• Leveraging previous and existing initiatives

Collaboration……Collaboration….Collaboration
