ASRSINTRODUCES... by Ed Cheaney
...ASRS Directline, a new quarterly publication
designed to return to the aviation public information
received at NASA’s Aviation Safety Reporting System
(ASRS) office in Mountain View, California. The
airmen now comprising the ASRS technical staff
occupy a unique vantage point from which to view the
operation of the aviation system. All are experienced
pilots or controllers who have taken on two demanding
tasks at ASRS. Firstly, they process incoming
ASRS reports to pinpoint the human or system factors
involved in each occurrence, remove all reporteridentifying
information from each record, and prepare
incident records for insertion into the computerized
database. Secondly, they conduct in-depth review of
aviation safety topics using the information in the
database.
Reports are currently arriving at a rate of about 3,000
per month. ASRS’s standard analysis process insures
that each one is examined and evaluated independently
by at least two members of the technical staff.
This means that every quarter each of these thoroughly
experienced professionals reviews an average
of 1,000 submissions describing incidents or situations

ASRS TECHNICAL ST
regarded as safety-critical by the pilot or controller
reporters.
Each report receives full and thoughtful attention.
Inevitably, however, a small number of reports examined
in each quarter strike an analyst as being especially
important, interesting, or novel depending on
the analyst’s particular experience and professional
sensitivities.
This quarterly journal is a forum in which the ASRS
technical staff speaks out on a selected set of topics
suggested by individually provocative reports received
at ASRS during the reporting quarter. Each staff
member nominated a number of topics; the final set
appearing here was screened for inclusion by the full
group. The discussions, each drafted by the staff
member submitting the chosen topic, are not research
study reports in the classic sense. Instead, they
present current thoughts, including subjective reactions,
about the operation of the aviation system by a
deeply involved, experienced, and uniquely qualified
group of professional airmen.
Reports received to August 1990 were
utilized in the preparation of articles
contained in this issue.
