MUMBAI: About 66% of the 542 Indian pilots who participated in a recent survey on fatigue causing “daytime sleepiness” admitted to falling asleep in the cockpit without informing the crew members. crew or go through periods of lethargy while on the job.
The survey included pilots engaged in regional, domestic and international operations and measured their fatigue on the Epworth Sleepiness Scale. “Based on their responses, it was found that approximately 54% of pilots experience severe excessive daytime sleepiness while 41% experience moderate daytime sleepiness,” the NGO survey said. implemented by the government. Organize safety issues. This explains why 66% of pilots said they experienced microsleep or accidentally fell asleep in the cockpit, the survey said.

Fatigue is a known causal factor in aviation accidents and incidents. It was one of the contributing factors to the 2010 Mangalore crash that killed 158 people. “Prolonged sleepiness and impaired judgment are believed to have contributed to this accident. The cockpit voice recorder said the Captain slept for 1 hour and 40 minutes of the 2 hour 5 minute flight,” it said.
Pilots cited early morning departures as the leading cause of fatigue (74%). The NGO’s founder, Captain Amit Singh, said: “The survey asked pilots a question about what time they would wake up if they had to report a flight departing at 6am. Most of the crew responded that they would wake up between 3am and 3:30am. This suggests that their body clocks are disrupted at the most critical period of rest.
Circulatory irregularities can leave you feeling exhausted and can have serious health consequences. Repeated flight duty during this period not only affects sleep quality, but missions over 10-12 hours will lead to poor perception which in turn affects flight safety.”
