The intercommunication system enables communications between which parties?

• A. Ground crew only
• B. Front to the rear cockpit only
• C. Between cockpits and to the ground crew
• D. Rear to the front cockpit only

Answer: (C)

The intercommunication system is designed to connect all crew in the aircraft and the ground crew for coordinating actions. It lets both cockpits talk to each other so pilots can share information and support during taxi, takeoff, approach, and emergencies, and it also provides a link to the ground crew for ground handling, pushback, clearance, and other ground operations. It isn’t limited to only ground personnel, nor to a one-way or single-pair cockpit talk. That broad capability—connecting both cockpits and the ground crew—is what makes it the best choice.
