Who Is ALPA? Represent 54,000 pilots at 41 Air Lines in North America IFALPA represents over 104,000 pilots at 90 member Associations Safety makes up a significant percentage of the operating budget Why? - “Schedule With Safety” been our motto for 76 years
Looking for Ways to Better Manage Risks Before They Become Accidents
ALPA Safety CommitteeProject Overview 178 Funded Projects Across 13 Technical Groups Plus 9 Accident Investigations
30 years ago… • The potential severity of runway incursions was fully realized • We also faced great risk of: • CFIT accidents • Windshear accidents • Mid-air collisions
Runway Incursion Likelihood Two commuter aircraft, Quincy, IL, November 11, 1996.
Runway Incursion Incidents in the US FAA and ICAO Data, 2003 - 2007
Runway Incursion Severity Runway Incursion, B737 & Metro III Collision at LAX February 1, 1991
Fatal Runway Incursion Accidents in the US, 1990 - 2007 • 1990 Atlanta, GA: B727 / Beech A100 • 1990 Detroit, MI: DC9 / B727 • 1991 Los Angeles, CA: B737 / SW4 • 1994 St. Louis, MO: DC9 / C441 • 1996 Quincy, IL: Beech 1900 / Beech A90 • 2000 Sarasota, FL: C172 / C152 • 2006 Lexington, KY: CRJ 100 112 Fatalities

Runway Incursion Mitigations • We cannot change the potential severity of an incursion • We can reduce the likelihood of an incursion through layers of mitigations • CAST recommendations made in 2002 to reduce frequency of incursions • Most not yet fully implemented
Highly Effective Mitigations: • Aircraft Moving Map • Add traffic to display • Runway occupancy advisories • Graphical/text of taxi and clearance limits • ASDE-X All great “high tech” solutions

Intelligent Design Many airports have exceeded their design capacity and were engineered for a different generation of aircraft.
Hotspots The challenge is to design Airports that Do Not Require Hotspots!

NOTAMSHas the time come to start over? • Technology exists to deliver a better product • Are they Intuitive? • Are they as effective at communicating critical information as we would like? • A “real challenge” for future growth
Training, SOPs, & Education Screen Capture from ALPA Web Site www.alpa.org
Investigation • Beyond Probable Cause…”Probability” of Cause, maybe? • We know Who did What. • Why did system not support expert operators? • System must be resilient to random errors made by expert operators.
SHEL ModelWe are the Liveware in the middle, surrounded by a system or “SHEL”
S = SoftwareTransfer of information between the human and supporting systems • Philosophy • Policy • Procedures • Checklists • Publications • Regulatory requirements • Information systems
H = HardwarePhysical and mental interactions between the person and machine or equipment • Systems management • Autoflight, Powerplants, Air conditioning, Pressurization, Flight Controls, aircraft configuration, Com/Nav/Ident radio(s) • Information displays • Flight, nav, weather, traffic, performance • Flight deck design and limitations • Restricted vision • Synthetic vision
E = EnvironmentInternalFactorsExternalFactors • Personal comfort • Temperature • Glare • Noise • Day/night • Visibility • Weather • Lights • Signs • Markings • Runway condition
L = LivewareThe nature of humans (physiology) and interactions between humans (psychology). • Voice communications • Phraseology • Speech content/rate • Language barriers • Read & hear back • Crew briefings • Crew interactions • Labor relations • Non-verbal cues

Knowledge (including training) Attitude Personality Situational Assessment Concurrent task management Prospective memory Psychological • Mental capabilities • Perceptions • Information processing • Attention span • Workload • Motivation • Time compressed decision making
SHEL ModelThe interface or edge between each component of the system is not clean and smooth, but rather jagged and fuzzy. This is another area where hazard and error exist.
Safety Improvements Wanted Require all runways crossings be authorized only by a specific clearance. A-00-67 Require runway crossing clearances be issued only after the previous runway has been crossed. A-00-68 Runway Incursions
