Final answer:
Passengers are required to use safety belts during certain flight phases to prevent injury. Ahaya's choice to walk and perform exercises is to avoid blood clots—a significant health risk during flights. Airline safety protocols, including the use of checklists, ensure the safety and health of passengers.
Step-by-step explanation:
Passengers in an aircraft are required to fasten their safety belts during critical phases of the flight such as takeoff and landing, as well as when the pilot deems it necessary due to turbulence or other safety considerations. This safety protocol minimizes the risk of injury during sudden movements of the aircraft. In the provided case study, we learn about Antônio, and his aisle-seat neighbor, Ahaya. After the seat belt light is turned off, Ahaya takes the opportunity to walk around and perform leg exercises. These activities are not just for comfort; they are essential for preventing potentially life-threatening blood clots, particularly on longer flights.
Airline protocols often include comprehensive checklists to ensure the safety of all onboard, similar to those in other industries, like medical or space travel. All these precautions and protocols, including the requirement for passengers to fasten their safety belts during certain times, contribute to the overall safety and health of everyone traveling on a commercial aircraft.
References to seat belts and airbag deployment serve as reminders of various safety measures taken in different modes of transportation to protect passengers from injuries during unexpected events. While the anecdote about the smushed cupcakes illustrates the consequences of sudden deceleration, it also highlights the importance of safety restraints in preventing more serious accidents.
