Environmental Factors

 There has been a great deal of research carried out in North America1 concerning environmental factors such as temperature, noise, lighting, etc. and a detailed Ergonomic Audit tool (ERNAP2) developed appropriate for aviation maintenance, which can assist in the evaluation of work environments, tooling and documentation. Further details may be found in Appendix Q. The Safety Health of Maintenance Engineering (SHoMe) tool (Appendix M) also looks at aspects associated with the working environment and tooling, although not in any great detail. It is appreciated that aircraft maintenance takes place in many different locations and environments, and that it is not always possible to carry out maintenance in a hangar maintained at a comfortable temperature, with adequate lighting and noise levels, etc. However, it should be recognised that environmental factors can contribute towards errors and efforts made to ensure that the environment is as ‘work-friendly’ as reasonably possible, e.g. putting an aircraft into a hangar, if space is available, rather than carrying out the work on the apron, where appropriate, even though this may take slightly longer to arrange a tow. The Health and Safety Executive (HSE) publish several useful documents which include guidance on the working environment. As a rule of thumb, what is good practice from a health and safety perspective is also likely to be good practice from an aviation safety perspective (albeit with a few debatable areas, such as wearing ear protection and being able to communicate adequately at the same time). Readers are referred to these publications for more general, non-aviation guidelines

Human Factor Introduction

Human Factor -  A  Person working in a maintenance environment requires human factor knowledge as per his job requirement. Human Factor Training  - Aviation safety relies on maintenance. When it is not done correctly , it may cause an incident or an accident.  Mistakes of maintenance personnel is difficult to detect. They are subjected to work in changing working in variety of adverse conditon. Regulatory Requirement : CAR 66 Module 09 Human factor - for get AMEL Human Factor   - Study of human capabilities and limitations in the workplace.   It is about study of the interaction  of maintenance personnel, the equipment used, the written and verbal procedures and  rules followed by them, and the environmental conditions of any system.  Aim of human  factors is to optimise the relationship between maintenance personnel and systems to improve  safety, efficiency, and well-being. HF - Fitting the man to the job and the job to th...

SHEL(L) Model

Model are used to understand human factor  as a framework around which human factor issues can be structured. SHEL(L),PEAR, Dirty Dozen  S - Software H - Hardware L - Liveware E - Environment                                         Liveware  is at the center of the model, is   the most critical and flexible component in the working  Environment and subject to considerable variations in performance and suffer many limitations.                           Physical size and shape.  In the design of workplace and equipment, body measurements and movements is considerd , which may vary according to factors such as age, ethnicity and gender. Human Factors inputs is provided  in the design process, and data for these inputs are available from anthropometry, biomechanics and k...

Information Processing Limitation

Human information processing  have limitations.   AMT requires support such as reference  to written material (e.g. manuals). Attention and Perception -  A proportion of ‘sensed’ data may be lost without being                              ‘perceived’.   Failing to  perceive  something  which   someone  has said to you, when you are concentrating on something else, even  though the words would have been received at the ear without any problem.  Information processing system has  ability  to perceive   something (such as a picture,                       sentence, concept, etc.) even though some of the data  may be missing.  Danger - people can fill in the gaps with  information from their own store of knowledge or experience, and this may lead to  t...
