Lion Air plane crash incident at Bali's Ngurah Rai Airport, Saturday (13/04/2013) and then, still can not know the exact cause. Chairman
of the National Transportation Safety Committee Tatang Kurniadi had
asked all parties not to estimate the causes of the accident.
Lion Air plane with flight number JT 904 departed from Bandung to Denpasar and piloted by M Ghazali. This aircraft is still fairly new and the airline Lion Air claims airworthy condition. Departing from the fact that, alleged that the cause of the plane failed to land events are triggered by human error.
Such as the cost of health experts presented Dr. Henry Mulyawan, SpBS (K), the human error factor is one of the main causes of the crash event. On pilot fatigue or fatigue is the biggest factor that most often leads to accidents. Very heavy workload may cause fatigue appeared on a pilot and has easily made the wrong decision.
Professional pilot, said Wawan, it requires good concentration. To obtain good concentration, of pilots should avoid fatigue, exhaustion both physical and psychological exhaustion.
PPDS faculty Flight Medicine Faculty of Medicine, University of Indonesia (Faculty of medicine) was added, to avoid fatigue, a pilot needs to live a healthy lifestyle is to exercise regularly, eat a healthy diet, adequate sleep or rest always utilize whenever there is time for breaks, and conduct self psychological therapy such as worship and pray regularly, and as often as you gather and positive social interaction with family and close friends.
However, not all pilots can live a lifestyle like that. Especially if the tasks assigned to it beyond what it should be. By exposure Wawan, the airlines must meet the standards of 1:4, ie each plane must provide 1 4 crew setting. This means that, each plane must provide 4 pilots and 4 co-pilot to fly a plane that is rotated.
If the pilot does not live a healthy lifestyle and be given a heavier workload, they are also susceptible to fatigue. Henry revealed the link between fatigue and activity following a pilot in the cockpit:
1. Fatigue and "mental block" and narrowing attention span.Research shows, fatigue can increase the frequency of personnel error, such as forgetting, is not accurate in controlling the aircraft, and other errors. In addition, fatigue also lead to mental block. Mental aspects related to barriers and lowering of associative recall. This can happen when a person is performing tasks that are relatively easy though. Consequently, the name was familiar to be remembered, and the important detail unnoticed, although shortly before he was able to remember well. This condition is a sign to look out for that are concerned are not prepared to think and act efficiently.
In other cases, the condition can lead to fatigue gaze and attention tends to narrow attention span is limited. Under these conditions, pilots tend to forget to check the instrument beyond the range of his attention, such as the side panels. He has focused on observation and / or difficulties which worried than those aspects that are more important in the flight situation.
Consequently, the reactions should be carried out on the signs given by the main instrument to change quickly into automatic reactions or reflexes are primitive. A natural reaction when someone starts to fear and panic. Furthermore it can be estimated that the concerned could make a mistake in taking the most essential or vital action.
2. Fatigue and flexibility in decision-making.Decision making is one important link in the act of flight. The more so when the pilot deal with emergency situations. Pilot fatigue conditions can lead to very adverse impact in this field.
In a state of fatigue, decision-making tends to be rigid. Airmen become inflexible in observing the various alternative actions the safest. This situation will further impact the opposite of what was expected, and certainly can be fatal.
3. Fatigue and "end deterioration".Other fatigue effects are interesting to watch is the error or errors that show up when the pilot began to approach or enter the landing area. This effect is often called end deterioration. An increasing trend aviator failure at final stages of flight. Interpretation of this effect is an unbearable fatigue aviator longer to relax or rest when the aircraft approached the end of the flight.
4. Fatigue and "series of errors".Fatigue effects not only result in a crash at the end of a flight sorties. This condition can also occur when taking off or not long after takeoff. This is usually caused by a series of errors (series of error) since the preparation of flight while still on the ground. Mission of a long flight, the flight crew arrived safely at a base to rest and the next day will resume flying, maybe a flight to return to the home base, or continue the flight to the base ahead of other operations missions.
