What is a necessary action for passengers during taxi, takeoff, and landing?

During taxi, takeoff, and landing, passengers are required to fasten their seat belts to ensure their safety. This regulation is crucial because these phases of flight are when the aircraft experiences the highest risk of turbulence, sudden stops, or emergencies. An appropriately fastened seat belt helps to keep passengers secure in their seats, reducing the likelihood of injury caused by unexpected movements of the aircraft.

While electronic devices may be used under certain conditions and remaining seated without belts might not necessarily be against regulations in all contexts, the standard procedure emphasizes the importance of wearing seat belts during critical flight phases. Unfastening seat belts at this time can lead to serious safety hazards, making it essential for passengers to keep their seat belts securely fastened.
