Who always has the right of way on the airport ground?

Answer: C — Airplanes

Airplanes always have the right of way on the airport ground due to their size, speed, and operational requirements. When an aircraft is taxiing, it is essential for ground vehicles, service personnel, and baggage carts to yield to the airplane to ensure safe and efficient operations on the tarmac. This priority is critical to prevent accidents and maintain the flow of air traffic, especially in busy environments like airports where many different types of vehicles and personnel are in constant motion. Consequently, all other ground operations must be coordinated around the aircraft's movements to uphold safety standards.
