Pilot error declines as factor in airline mishaps

03.01.2008
The number of airline mishaps attributed to pilot error significantly declined between 1983 and 2002, according to an analysis conducted by researchers at the Johns Hopkins Bloomberg School of Public Health.

While the overall rate of airline mishaps remained stable during that time, the proportion of mishaps involving pilot error decreased 40 percent. The rate of mishaps related to a pilot’s poor decision-making declined 71 percent. The researchers attribute the decline to better training and improvements in technology that aid pilot decision-making. The findings are published in the January 2007 edition of Aviation, Space, and Environmental Medicine.

“A 40 percent decline in pilot error-related mishaps is very impressive. Pilot error has long been considered the most prominent contributor to aviation crashes,” said the study’s lead author, Susan P. Baker, MPH, a professor with the Johns Hopkins Center for Injury Research and Policy and the Bloomberg School’s Department of Health Policy and Management.

The study examined 558 airline mishaps between 1983 and 2002. Baker and her colleagues also looked at the circumstances of pilot error, which they characterized as carelessness on the part of the pilot and crew, flawed decision-making, mishandling of the aircraft or poor crew interaction.

Other key findings of the study included:

Mishaps related to bad weather—the most common decision-making error—dropped 76 percent.

Mishaps caused by mishandling wind or runway conditions declined 78 percent.
Mishaps caused by poor crew interaction declined 68 percent.
Pilot error was most common during taxiing, takeoff, final approach and landing of the aircraft.
The mishap rate increased the most when aircraft were being pushed back from the gate or standing still, but pilot error was least common in such mishaps.

Mishaps during takeoff declined 70 percent.

While the overall rate of pilot error mishaps declined, the reductions were offset by increases in mishaps that did not involve error by pilots; some involved errors by air traffic control or ground crews. The researchers also noted that there is a need to improve safety during the times when the aircraft is motionless on the ground or being pushed back from the gate. The study found that mishaps during these times more than doubled from a rate of 2.5 to 6 mishaps per 10 million flights.

“Trends indicate that great progress has been made to improve the decision-making of pilots and coordination between the aircraft’s crew members. However, the improvements have not led to an overall decline in mishaps. The increase in mishaps while aircraft are not moving may require special attention,” said Baker.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
