How many agents are required to hook up a tower to an aircraft?

The correct answer is two agents are required to hook up a tower to an aircraft. This process typically involves ensuring safe and efficient operation when connecting ground support equipment, like a ground power unit or a preconditioned air unit, to the aircraft.

Having two agents allows for coordinated efforts; one agent can operate the equipment while the other can assist with connecting the hoses or cables, checking for proper alignment, and ensuring safety protocols are followed. This two-person approach enhances communication and minimizes the risk of accidents or errors, thereby promoting a safer and more efficient operation on the ramp.
