Controller-Pilot Data Link Communications (CPDLC) Case Study

Some of the computer technologies I recognized were the large workstations and monitors being utilized by the air traffic controllers, and the smaller input/output units being used by the pilots. The air traffic controllers use the workstations with specialized software to communicate directly with the onboard aircraft systems to provide real time flight and aircraft information to the controllers. Large monitors are used to display the aircraft and flight information to make the data useful to the controllers. The pilots use the Controller-Pilot Data Link Communications (CPDLC) to send and receive messages to the air traffic controllers.

The benefits of using the CPDLC for controller to pilot communications are better efficiency and more effective communication. Utilizing the CPDLC for controller to pilot communication is more efficient than radio communication. Redundant and non priority messages can be sent and received without time consuming radio proto calls, tying up radio channels, or other distractions. These lead to the controllers and pilots being able to focus on other priorities. Also, using the CPDLC is more effective than radio communication. Text messages and written word are more clear and concise ways of communication. With radio communication you may have static, language/accent barriers, or misinterpretation.

The challenges and risks of using CPDLC are cost and pilot distractions. The costs of implementing and sustaining a data link system are much greater than those of radio communication systems. The cost of training for the new system must be considered as well. Another challenge is that of pilot distractions. In today’s digital cockpit world, pilots are inundated with various system messages, warnings, and various chimes to alert pilots to all these messages including flight attendant calls. A pilot Kent Wien (2012) writes, “The look around the cockpit for the various clues to...
