Autogenic Feedback Training Improves Pilot Performance During Emergency Flying Conditions 24 pages. [PDF 187K]
Emergencies in flight create stress factors that can seriously degrade pilot performance. A recent study examines how autogenic feedback training improves pilot performance during high-stress and emergency situations.
June 1993
Research Identifies Common Errors Behind Altitude Deviations 24 pages. [PDF 352K]
Nearly 500 pilots and 48 air traffic controllers provided data in a recent study designed to analyze an alarming increase in altitude deviations.
May 1993
Volcanic Hazards and Aviation Safety: Lessons of the Past Decade 21 pages. [PDF 193K]
Avoiding the ash-laden cloud from a volcano is the only way to guarantee that an aircraft is not damaged by the cloud’s dangerous particles, which can destroy an aircraft engine and threaten flight safety. Nature remains the ultimate force.

During Adverse Conditions, Decelerating to Stop Demands More from Crew and Aircraft 25 pages. [PDF 164K]
Hydroplaning, gusting cross winds and mechanical failures are only a few of the factors that contribute to runway overrun accidents and incidents after landing or rejecting a takeoff. Improvements in tire design, runway construction and aircraft systems reduce risks, but crew training remains the most important tool to stop safely.
February 1993
U.S. Report: Delays Still Plague Efforts to Harmonize Commercial Transport Airplane Standards 20 pages. [PDF 134K]
Despite 10 years of joint efforts to harmonize certification standards, the United States and European aviation authorities still have much to accomplish. A U.S. study says that a new joint strategy may speed the process.
January 1993
Rejected Takeoffs: Causes, Problems and Consequences 25 pages. [PDF 180K]
Rejected takeoffs involve multiple risks and require a high level of pilot perception, judgment and procedural skill. This study looks at human factors associated with rejected takeoffs.
