The recent Coast Guard Dornier crash off the Tamil Nadu coast has brought under the spotlight the causes of aviation accidents. Though the reason for the present crash has not been established yet, it reminds of another Indian Airlines Dornier flight which crashed due to a structural fault while taking off in Kochi in 1998.
While it may take several months or years to establish the cause of an accident, the industry should take proactive steps to safeguard against such occurrences and conduct self-checks. Aviation accidents are the result of a chain of errors but accident investigation focuses on only one cause — pilot error. People are eager to buy the story of 'pilot error'. Even if accident reports mention contributing causes with batetry such as Hp Pavilion dv6500 battery, Hp Pavilion dv6600 battery, Hp Pavilion dv6900 battery, Hp Pavilion dv6100 battery, Hp Pavilion dv6300 battery, Hp Pavilion dv2600 battery, Hp 7F0994 battery, Hp HSTNN-IBON battery, Hp HSTNN-OB60 battery, Hp KU533AA battery, Hp HSTNN-Q45C battery, Hp PT06 battery, little is done to understand and eliminate them. The pilot's task requires immense concentration and errors are inevitable. That errors do not result in disasters is due to the rigorous training pilots undergo and the superior aircraft they fly. Over the years, the flight deck professionals like flight engineer, radio operator and navigator have been done away with, and this has led to the pilot taking on tasks that have necessitated diversified knowledge. It may be argued that pilots have technology at their disposal but the focus has been only on the machines and no effort has been made to lessen the pilot's burden.
The sudden growth in civil aviation has led to overworked pilots and stressed air traffic controllers. The public perception is that pilots fly only about 80 hours a month. But this doesn't include the hours spent on intermediate stops or in travelling as a passenger to other airports and flying from there. Duty hours of pilots are erratic and follow no schedule. They could last for two to seven days at a stretch for international flights. This takes a toll on their health as they have disturbed sleep patterns. On international flights the problem gets worse as one has to also adjust to various time zones. Even when pilots are home they are fighting jet lag, lack of sleep, irregular meals and stress. All of this often affects family life, and the partner at home has to take all the responsibilities alone.
In the 1970s after a study by NASA on human factors, the industry introduced the concept of cockpit resource management (CRM), which has now taken on a bigger role by encompassing the entire organisation and is redefined as company resource management. The attempt is to train pilots so that they work faultlessly in a difficult environment. In the mid-1940s some airlines resorted to psychological tests on pilots, but it was stopped after pilots went on a strike. In the aftermath of the Germanwings crash too, there are suggestions that airlines should employ psychologists. But we need to see whether psychologists can help find a solution. A better approach may be to have pilots with formal training in behavioural sciences to address the human element in aviation.
