AVIATION REGULATION AND SAFETY
A good safety record is a judgment of past performance but does not guarantee the future (PARLIAMENT of AUSTRALIA 2004) [ref.3]. Airline operators, pilots, mechanics, flight attendants, government regulators and makers all have a stake in making aviation as safe as possible. Howbeit, they are still many aircraft had been crash due to many other reasons, such as the pilot’s error (which we called as the “human factor”), factor of fatigue, weather, congestion and others.
However, the main safety issue that facing aviation regulator today is FATIGUE. The word fatigue is used in everyday living to describe a range of afflictions, varying from a general state of tiredness to a specific work induced burning sensation within muscle (Better Health Channel) [ref.1]. Physiologically, fatigue describes the failure to continue functioning at a prescribed work rate in the presence of an increased perception of effort. (Better Health Channel) [ref.1] .Fatigue is ubiquitous in everyday life, but becomes particularly marked during heavy exercise. The development of fatigue is characterized by an initial, disproportionate increase in the perception of effort required to maintain or increase the work output before the inability to exert the required force is experienced. Fatigue can be dangerous when performing tasks that require constant concentration. When someone is sufficiently fatigued, they may experience micro sleeps that can cause them to lose concentration; however, objective cognitive testing should be done to differentiate the neurocognitive deficits of brain disease from those attributable to tiredness. Laconically, this is the roots of the happening of accident. (Better Health Channel) [ref.1]
Nowadays, the safety outcome may be expressed in a number of different ways with each having its own advantages and disadvantages. The simples form is a count of relevant accidents. However, there is tension between achieving aviation safety that preserves public confidence, thus the Australian aviation regulatory has been keep developing and improving.
1. Autopilot requirement.(Australian Government Civil Aviation Safety Authority ,2006) (ref.4)
December 1997, the introduction of the autopilot system, this has decreased the workload of pilot. A single pilot operation of an airplane under the instrument flight rules is widely accepted as being demanding and imposing a high workload on the pilot. This high workload environment can contribute to serious errors in fuel calculation, assessment of weather, accuracy of navigation, adherence to air traffic control clearance requirements, the application checklists and judgment under stress. In part, these errors can be caused by the instantaneous demands of command decision making and airplane manipulation. The demand and workload can be significantly reduced if the pilot is supported by an autopilot.
