What are the three types of human error in aviation?

Table of Contents

There are three main areas in aviation, of interest to human factors professionals and managers who wish to understand and reduce human error.

Pilot or Flightdeck error.
Air traffic Control error.
Maintenance Error.

What are the four levels of the human factors and analysis classification system?

Drawing upon Reason’s (1990) concept of latent and active failures, HFACS describes four levels of failure: 1) Unsafe Acts, 2) Preconditions for Unsafe Acts, 3) Unsafe Supervision, and 4) Organizational Influences.

What are the four consequences of human error?

Human errors have the following impact: high social and economic cost, equipment safety, maintenance performance efficiency and effectiveness, equipment productivity, incidents and accidents and fatality [26].

What are the two types of failures that cause human errors OSHA?

There are two main types of human failure: errors and violations.

What are the three components of Deming’s descriptions of process?

Technical, Operational, Environmental.

Who invented HFACS?

The HFACS framework was developed by Dr. Douglas Wiegmann and Dr. Scott Shappell in the United States Navy. The early ’90’s were a turbulent time for the Navy Department as they suffered an exceedingly high rate of aviation accidents.

What are the levels of HFACS?

HFACS uses the same levels presented by Reason in his model; organizational influences, unsafe supervision, preconditions for unsafe acts and unsafe acts. Within each level of HFACS, causal categories were developed that identify the active and latent failures that occur (see Table 1 for a definition to each causal category).

How has the HFACS method changed over time?

When the studies in the literature are examined, it is seen that the HFACS method has been modified over time according to different accidents or ship types.

What is the purpose of HFACS guide?

Mishaps are rarely attributable to a single cause, but are often the end result of a series of errors. The purpose of the HFACS guide is to aid the investigator through a systematic, multidimensional analysis of potential human factors to explain what and why a mishap occurred.

How can HFACS be used to reduce accident and injury rates?

HFACS can also be used proactively by analyzing historical events to identify reoccurring trends in human performance and system deficiencies. Both of these methods will allow organizations to identify weak areas and implement targeted, data-driven interventions that will ultimately reduce accident and injury rates.
