Passengers notice during the night flights that the captain is softening cabin lights during takeoff and landing, and some may not know why everyone realizes it is a great safety precaution without knowing its cause.
According to what was published by the British newspaper “Express”, some theories indicate that the reason is due to the reduction of optical light pollution in the atmosphere, but this is not the case for sure. The correct reason was revealed by Patrick Smith, the pilot and author of ‘Cockpit Confidential’, explaining that he was a precaution in an emergency.
Prepare the eyes of passengers
“Darkening the lights allows your eyes to get used to the darkness beforehand, so your eyes do not suddenly blind if something happens and the energy sources are cut off, and you rush to the doors in the dark or smoke,” Smith says.
Smith said, “Emergency path lighting and instructional panels will also be more visible … and make it easier for you to see outside.”
The risk of takeoff and landing
While the trained pilot, Rohan Bhatnagar, explained that the lights dim the safety measure, he wrote: “It is a safety measure for the aircraft, because the possibility of collision is high during takeoff and landing.
He added that “during any collision when the lights go out, the human eye takes time to adapt to complete blackout so that the lights are dimmed a factor helping to facilitate the evacuation of passengers quickly in an emergency.”
“The lighting is also dimmed so that fluorescent illuminated indicative panels are visible in the corridor in an emergency, and visible to passengers,” Bhatnagar added.
High safety precautions
Although aircraft flights are widely cited as one of the safest ways to travel, the International Air Transport Association (IATA) found that in 2016 there was an average of one accident per 2.86 million flights. But the most vulnerable times are takeoff and landing, which is why many safety precautions are in place.
According to Ben Sherwood, author of “The Survivors Club … Secrets and Sciences that can save your life,” the take-off and landing phases are the most dangerous of all air travel. So people are advised to follow the rule not to do anything that impedes evacuation in an emergency, such as listening to music, taking off their shoes or sleeping. After takeoff, the chances of danger or crash are reduced, and passengers can sit back relaxed and enjoy their flight.
Close the mobile phone
Other safety precautions include switching your mobile phone to the flight mode option. Although it is unlikely that operating the phone may cause the aircraft to crash, it may have troublesome consequences for pilots, who transmit important messages throughout the entire flight including air traffic control. And the phone can interfere with the cabin equipment, even if it is not used by a passenger.
According to the Civil Aviation Authority (CAA): “Modern passenger aircraft are highly dependent on electronic communication and navigation systems that operate based on electromagnetic energy transmission, and therefore may be subject to electromagnetic interference.”
She added that mobile phones and many electronic devices transmit electromagnetic signals when they are not in flight mode as they try to connect to a communications network.
Additionally, the CAA warns that “the cumulative effect of a large number of mobile phones or simultaneously sending electronic devices when not in flight mode, especially during critical stages of the flight, such as takeoff and landing, remains a major concern”.
Hospitality crew instructions
Although most phones cannot receive signals from phone towers, they still cause noise to pilots. The cabin crew onboard each aircraft clarifies what devices may or may not be used at the beginning of the flight.
A CAA spokesperson told the newspaper “Express” that “all passengers must comply with the flight’s crew instructions and regulations, which include the information provided during flight during briefing sessions. Anyone who does not comply with these instructions is a crime and can be prosecuted if he insists On the violation and did not immediately retract it. “
