What does 'taxi' imply for an aircraft?

The term 'taxi' in aviation refers specifically to the movement of an aircraft on the ground, typically either after it has landed or before it takes off. This movement occurs on the airport's taxiways and runways, and it is crucial for safely navigating the aircraft to and from the runway.

Understanding that taxiing occurs before takeoff and after landing helps clarify the operational procedures that flight attendants and flight crews must adhere to. It involves various tasks such as communication with air traffic control, maintaining awareness of ground traffic, and ensuring the aircraft is prepared for safe takeoff or disembarking passengers after landing.

In contrast, the other options refer to different phases of flight: preparing for takeoff relates to pre-flight checks and readiness, flying at cruising altitude indicates a steady flight after ascent, and landing describes the final approach and touchdown on the runway.
