Physical Environment

             AME is work in a variety of different   environments, from ‘line’ to ‘base’, in all types of weather and climatic conditions, day and night. AME encounters the impact of noise, fumes, illumination, climate and temperature, motion and vibration, as well as the  requirement  to work in confined spaces and issues associated with the general working environment.
CAR 145.A.25 (c) The working environment including aircraft hangars, component workshops and office accommodation is appropriate for the task carried out and in particular special requirements observed. Unless otherwise dictated by the particular task environment, the working environment must be such that the effectiveness of personnel is not impaired:
1. Temperatures must be maintained such that personnel can carry out required tasks without undue discomfort.
2. Dust and any other airborne contamination are kept to a minimum and not be permitted to reach a level in the work task area where visible aircraft/component surface contamination is evident. 
3. Lighting is such as to ensure each inspection and maintenance task can be carried out in an effective manner.
4. Noise shall not distract personnel from carrying out inspection tasks. Where it is impractical to control the noise source, such personnel are provided with the necessary personal equipment to stop excessive noise causing distraction during inspection tasks.
5. where a particular maintenance task requires the application of specific environmental conditions different to the foregoing, then such conditions are observed. Specific conditions are identified in the maintenance data.
6. Working environment for line maintenance is such that the particular maintenance or inspection task can be carried out without undue distraction. Therefore where the working environment deteriorates to an unacceptable level in respect of temperature, moisture, hail, ice, snow, wind, light, dust/other airborne contamination, the particular maintenance or inspection tasks must be suspended until satisfactory conditions are re-establish
Noise - can have both short-term and long-term negative effects. it can be annoying, can interfere with verbal communication and mask warnings, and it can damage hearing
Fumes - maintenance of aircraft involves working with a variety of fluids and
chemical substances. Fumes can cause problems for engineers mainly as a result of inhalation, but they can also cause other problems, such as eye irritation.
Illumination - Work to be conducted under proper lighting conditions. cones in the retina of the eye require good light to resolve fine detail.
Climate and Temperature - Humans can work within quite a wide range of temperatures and climatic conditions,but performance is adversely affected at extremes of these.
Motion and Vibration- Any sensation of unsteadiness may distract an engineer, as he may concentrate more on keeping his balance than the task.Vibration  is usually associated with the use of rotating or percussive tools and ancillary equipment
Confined Spaces - Working in any confined space, needs to be managed carefully. engineers should ideally work with a colleague who would assist their ingress into and egress out of the confined space. Good illumination and ventilation within the confined space will reduce any feelings of discomfort. In addition, appropriate safety equipment, such as breathing apparatus or lines must be used when required.

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...
