Is it permissible for a vehicle to pass an aircraft on an adjacent taxiway if traveling in the same direction?

The correct answer emphasizes the importance of safety and adherence to established protocols on the ramp and taxiways. In aviation operations, aircraft have the right-of-way because they are larger and heavier than ground vehicles, and their movements are critical for the safety and efficiency of airport operations. Allowing vehicles to pass aircraft without strict control could lead to accidents or conflicts between aircraft and vehicles.

In this scenario, the correct interpretation is that vehicles should not pass an aircraft on an adjacent taxiway while it is moving or stationary, regardless of the direction or position. This rule is in place to ensure that pilots can operate their aircraft without being distracted or concerned about vehicle movements nearby, thereby maintaining a safe operational environment for all parties involved. Ground control plays a pivotal role in supervising and directing movements, but the fundamental principle remains that aircraft operations take precedence.
