During the post-flight phase, what does "standing" indicate?

The term "standing" during the post-flight phase refers specifically to the aircraft being stationary after it has arrived at the gate. When an aircraft is described as "standing," it indicates that it has completed its landing, navigated to the designated gate, and is now at rest, awaiting the completion of deboarding and any subsequent maintenance or servicing tasks. This status is crucial for ground operations, as it signifies that the aircraft is no longer in motion and is available for passenger disembarkation, luggage handling, and other post-arrival activities. In contrast, the other answer choices do not represent this exact scenario, as they either imply the aircraft is still in motion or have not reached the final resting point.
