Although prevention of human error begins at the initial stages of the design, it is still not possible to eradicate all sorts of human error. In addition to that, the role of human factor makes it impossible to completely eliminate human error. However, error management approach allows the reduction in the frequency and the consequences of the errors associated with aircraft performance.
Aviation industry holds a particular amount of stress related to the lives of millions of people and economic consequences. This stress combined with incomplete information and inaccurate or inadequate account for poor decisions made in aviation performances. Moreover, poor aviation leadership also contribute to compromising aviation safety.
Human performance is influenced by several human factors such as human comfort zones, limitations, and abilities. Human factors need to be considered to optimize maximum performance between people and the systems in which they work. Human factors need to be analyzed systematically to treat human performance issues.
In the field of aviation, it has been realized that the underlying cause in almost 70% to 80% of the aviation accidents is human error. Prevention of the error chain calls for the comprehensive analysis of the chain of events that occurred during it. Clear starting point in majority of the error chains can be identified by thorough and detailed analysis of the error chain.
Pilots are mostly engaged in complex environments which routinely impose high stress which in turn can induce pilot error resulting in a threat to flight safety. The pilot error myth today affects the performance of the pilots in the skies by putting unrestrained pressure on them which disturbs the attitudes of the flight crew.
Among the many cognitive biased errors, the two most common ones are the attentional biased error and attention tunneling. Attention biased error are based on the emotional aspects of the person making the decision. On the other hand, attention tunneling is the allocation of attention from a particular issue to another issue at hand. This results in the neglected event creating considerable flight safety threat.
Goldilocks zones of workload is referred to the just the right amount of work required in a particular situation. Correct amount and delivery of awareness is necessary to ensure that the flight crew performs the adequate amount of workloads required in any situation.
Fatigue poses a serious threat to the flight crew in optimal performance by effecting different aspects of human functioning. Symptoms of fatigue may include sleepiness, decreased concentration, or poor visual ability which may affect the decision-making skills, poor performance, and lack of proper motivation.
In aviation, situational awareness is defined as the understanding of the pilot to perceive a mental picture of the interrelationship between the aircraft and the location, configuration, energy state, external factors and the related consequences involved regarding the aviation safety.
In human-automation interaction, mode confusion holds the most potential to be the largest threat to commercial aviation safety. This situation is produced when the pilot fails to understand the behavior of the mode of the automation which results in inconveniences ending in tragedy.
In order to address the miscommunication regarding the installation of wrong kind of seat belts, it advisable to engage HFACS and HFIX to ensure maximum human performance among the flight crew. Moreover, the HFACS and HFIX frameworks provides the assistance to remedy human error in flight operations.
