Who has the right of way when taxiing?

The correct answer highlights the principle of safety in aircraft operations while taxiing. An aircraft that is least able to maneuver, typically due to its size, operational status, or specific limitations, is granted right of way to ensure safe movement on the ground. This understanding reflects the priority given to aircraft that cannot change trajectory easily, which often includes larger aircraft or those with certain mechanical issues.

In real-world aviation scenarios, this rule is crucial for preventing collisions and ensuring smooth traffic flow on the ground. By ensuring that the most vulnerable aircraft have the right of way, protocols are established that prioritize safety above all else.

The context of this choice resonates with established aviation practices where operational limitations can dictate the flow of traffic. Other options, while relevant in different contexts, do not carry the same critical safety implications as recognizing and accommodating the limitations of the aircraft in question.
