1. Introduction
The aviation industry is a 24 hour operations business and human resource continue to face challenges that are associated with fatigue on a day to day basis. In general a fatigue is a feeling of tiredness and the inability of performing a task effectively. A fatigued person will be less cautious, less able to process information, and will be encounter to a slower response times and less concern to operational environment compared to a person who is not fatigued. Therefore, to improve productivity and safety of maintenance personnel, the aviation industry has find practical solutions that can reduce or eliminated fatigue related errors which has an impact on safety and quality of work.
Each person has a developed
