Which aircraft has the right of way when taxiing?

The principle behind right of way while taxiing is primarily focused on the aircraft's maneuverability. When considering which aircraft should have the right of way, it is generally the least maneuverable aircraft that is prioritized. This is because less maneuverable aircraft, such as larger jets or those with a more complex taxiing procedure, require more space and time to change direction or speed.

By giving the right of way to the least maneuverable aircraft, it ensures safety and minimizes the risk of collision during taxi operations. This approach helps to maintain an organized flow on the ground, where space and time to react can be limited.

The emphasis on maneuverability is crucial in aviation operations, and as such, the other options—most maneuverable, those with the most fuel, and the largest aircraft—do not align with the fundamental safety rules governing taxi operations.
