What should be done while taxiing on the ground?

During taxiing on the ground, the focus is on safety and readiness for flight. Fastening seatbelts is crucial because it ensures that all occupants are securely seated and ready for when the aircraft begins to move. This safety measure helps prevent injury in the event of sudden stops or pilot maneuvers during taxiing.

While other actions, such as performing equipment checks, preparing for exit, and communicating with crew, are important in different contexts, fastening seatbelts is specifically critical during this phase as it directly relates to the safety and security of the passengers and crew before the flight takes off.
