Summary
A new classification system, Aviation Causal Contributors for Event Reporting Systems (ACCERS), was developed to identify pilot error causes in safety reports. ACCERS demonstrates reliability and validity for improving aviation safety analysis.
Area of Science:
- Human Factors and Aviation Safety
- Cognitive Psychology in Aviation
- Safety Management Systems
Background:
- Aviation Safety Action Program (ASAP) enables voluntary pilot self-reporting of incidents.
- Extracting error causes from pilot narratives is challenging for analysts.
- A standardized taxonomy is needed for classifying pilot error causes.
Purpose of the Study:
- Develop a reliable and valid classification system for pilot error causes.
- Create the Aviation Causal Contributors for Event Reporting Systems (ACCERS) taxonomy.
- Facilitate the analysis of human performance in aviation safety.
Main Methods:
- Literature review, pilot interviews, and card-sorting tasks informed ACCERS development.
- Studies 1 and 2 established the initial ACCERS structure.
- Studies 3a and 3b tested ACCERS reliability and utility through independent pilot classifications.
Main Results:
- Initial evidence supports the internal and external validity of ACCERS.
- Pilots achieved adequate agreement in classifying error causes using ACCERS.
- The taxonomy provides a structured approach to analyzing pilot-reported events.
Conclusions:
- ACCERS is a useful tool for analyzing human error in pilot ASAP reports.
- Future research should refine ACCERS organization and applicability to other aviation roles.
- The system has potential applications in any self-reporting error system.

01:12Types of Errors: Detection and Minimization
Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.

01:15Systematic Error: Methodological and Sampling Errors
In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

01:03Data Validation
Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.

01:15Data Validation
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

01:21Types of Reports II: Incident or Occurrence Report
An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.
Purposes:
In the healthcare industry, reports play a crucial role in documenting incidents within an agency. The primary objective of these reports is to ensure patient safety, uphold the...

01:28Criteria for Causality: Bradford Hill Criteria - II
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:
