Human error is defined as a human action with unintended consequences. When you couple error with aviation maintenance and the negative consequences that it produces, it becomes extremely troublesome. Training, risk assessments, safety inspections, etc., should not be restricted to an attempt to avoid errors but rather to make them visible and identify them before … Read more
The PEAR model is a practical framework used in aviation maintenance human factors to identify and evaluate the key elements that influence human performance and safety. By focusing on people, environment, actions, and resources, it helps maintenance organizations better understand workplace challenges, reduce errors, and improve overall maintenance effectiveness. There are many concepts related to … Read more
The development of human factors has evolved over centuries, shaped by advances in science, engineering, and aviation. From early studies of human body proportions to modern aviation safety systems, human factors have played a critical role in improving performance, reducing errors, and enhancing safety. In aviation maintenance, understanding this historical evolution helps explain how current … Read more
FAA Involvement The FAA has had a formal involvement in this issue since 1988. That was the year the first Human Factors Issues in Aviation Maintenance and Inspection National Conference was conducted, and that effort reflects a working relationship between government research and industry activity. This yearly event includes airlines, suppliers, manufacturers, schools, and government … Read more
Helicopter Weight and Balance General Concepts All the terminology and concepts that apply to airplane weight and balance also apply generally to helicopter weight and balance. However, there are some specific differences that need to be identified. Most helicopters have a much more restricted CG range than airplanes. In some cases, this range is less … Read more
Datum The datum is an imaginary vertical plane from which all horizontal measurements are taken for balance purposes, with the aircraft in level flight attitude. If the datum is viewed on a drawing of an aircraft, it would appear as a vertical line that is perpendicular (90 degrees) to the aircraft’s longitudinal axis. For each … Read more
