Human Behavior
Studies of human behavior have tried to determine an
individual's predisposition to taking risks and the level of
an individual's involvement in accidents. In 1951, a study
regarding injury-prone children was published by Elizabeth
Mechem Fuller and Helen B. Baune, of the University of
Minnesota. The study was comprised of two separate groups
of second grade students. fifty-five students were considered
accident repeaters and 48 students had no accidents. Both
groups were from the same school of 600 and their family
demographics were similar.
The accident-free group showed a superior knowledge
of safety, were considered industrious and cooperative
with others, but were not considered physically inclined.
The accident-repeater group had better gymnastic skills,
were considered aggressive and impulsive, demonstrated
rebellious behavior when under stress, were poor losers, and
liked to be the center of attention. One interpretation of this
data—an adult predisposition to injury stems from childhood
behavior and environment—leads to the conclusion that
any pilot group should be comprised only of pilots who are
safety-conscious, industrious, and cooperative.
Clearly, this is not only an inaccurate inference, it is
impossible. Pilots are drawn from the general population and
exhibit all types of personality traits. Thus, it is important that
good decision-making skills be taught to all pilots. |

Historically, the term "pilot error" has been used to describe
an accident in which an action or decision made by the
pilot was the cause or a contributing factor that led to the
accident. This definition also includes the pilot's failure
to make a correct decision or take proper action. From a
broader perspective, the phrase "human factors related" more
aptly describes these accidents. A single decision or event
does not lead to an accident, but a series of events and the
resultant decisions together form a chain of events leading
to an outcome.
In his article "Accident-Prone Pilots," Dr. Patrick R. Veillette
uses the history of "Captain Everyman" to demonstrate how
aircraft accidents are caused more by a chain of poor choices
rather than one single poor choice. In the case of Captain
Everyman, after a gear-up landing accident, he became
involved in another accident while taxiing a Beech 58P
Baron out of the ramp. Interrupted by a radio call from the
dispatcher, Everyman neglected to complete the fuel crossfeed
check before taking off. Everyman, who was flying
solo, left the right-fuel selector in the cross-feed position.
Once aloft and cruising, he noticed a right roll tendency
and corrected with aileron trim. He did not realize that both
engines were feeding off the left wing's tank, making the
wing lighter. |
