What type of equipment is NOT commonly utilized for cockpit communication?

Ground handling tools are not typically associated with cockpit communication. Instead, their primary function is to assist with the physical management of the aircraft while on the ground, such as during loading, unloading, and towing operations. They do not facilitate communication between pilots, air traffic control, or other aircraft.

In contrast, radios, intercoms, and transponders are integral components of cockpit communication systems. Radios enable voice communication with air traffic control and other aircraft, intercoms facilitate communication within the cockpit and between crew members, and transponders transmit information about the aircraft's location and intentions, enhancing situational awareness. Each of these tools plays a crucial role in ensuring safe and efficient operations in the air and on the ground.
