Benefits of Data SharingBenefits of Data Sharing
• Data sharing produces sound analysis to target emerging safety threats and prioritize and effective interventions to reduce undesirable events from occurring.
• Additional data sharing benefits are:– Data Fusion
• Combining information resources creates a more accurate picture of how aircraft operations, air traffic procedures, and national policies interact.
– Data Driven Decision Making• Complete and accurate data enable better issue analysis and sound
decision-making.
– Data driven investment and resource allocation decisions.
A collaborative Government and Industry initiative on data sharing & analysis to proactively discover safety concerns before accidents or incidents occur, leading to timely mitigation and prevention.

What is ASIAS….
ASIAS is Governed by Formal Principles
Non-punitive reportingData used solely for
advancement of safety
Sensitive data is de-identified
Analyses approved by an ASIAS Executive Board
Data protected and aggregated
Types of Proactive Safety Analyses

Data Fusion provides Valuable Insights Data Fusion provides Valuable Insights to Future Threats (Precursors)to Future Threats (Precursors)
TAWS Alert Mitigation Strategy• Near Term:
– Use of RNAV/RNP and other procedures to reduce unnecessary terrain alerts and to provide better separation from terrain
– Evaluate Minimum Vectoring Altitude (MVA) in relation to terrain and traffic flows in high-terrain airports
• Longer term:
– Having GPS + Software Version 218 or greater reduces unwarranted warnings when the aircraft is not in imminent danger
– Increases the effectiveness of EGPWS alerting during approach phase
Data FusionCombining information resources creates a more accurate picture of how aircraft operations, air traffic procedures, and national policies interact.
Data Driven Decision MakingComplete and accurate data enable better issue analysis and sound decision-making.
EGPWS Mode-2 Pull Ups – Pre 218
EGPWS Mode-2 Pull Ups – Post 218 (about 20X Less Frequent)
Effective Interventions Can be implemented to prevent undesirable events
Commercial Aviation Safety Team (CAST)
VisionKey aviation stakeholders acting cooperatively to lead the world-wide aviation community to the highest levels of global commercial aviation
safety by focusing on the right things.
MissionEnable a continuous improvement framework built on monitoring the
effectiveness of implemented actions and modifying actions to achieve the goal.
Goal Reduce the US commercial aviation fatal accident rate 80% by 2007.
And Maintain a continuous reduction in fatality risk in US and International
commercial aviation beyond 2007.

ASIAS Results Combined with CAST Implementation Can Inform Resource Cost
Versus Risk Reduction
Areas to Consider• Ensure that findings from safety programs such as CAST and
ASIAS be used in conjunction with NextGen and other Airspace programs to prioritize performance based navigation (PBN) solutions and Airspace re-design procedures to address Tactical safety issues such as TAWS, TCAS and un-stabilized approaches.
• Ensure that collaborative Government and Industry prognostic data analysis and sharing programs have established long term funding streams and be accelerated to provide benefit to the flying public.
• Government & Industry programs such as CAST and ASIAS should serve as the model for programs in other segments of the Aviation community
• Ensure protection for voluntarily supplied safety information
