More recently, communication technology has advanced beyond radios with the implementation of data link systems. A controller–pilot data link communication (CPDLC) system allows aircraft to transmit and receive voice, text, and pictorial information. In many ways, this technology can be thought of as a text messaging system between pilots, controllers, and airline dispatchers. An example of a data link system is the aircraft communications addressing and reporting system (ACARS). A key feature of ACARS is the automatic detection and report of each major flight phase (out of the gate, off the ground, on the ground, and into the gate) through aircraft sensors. The system automatically transmits “pings” from the aircraft to ground communication stations.
Air traffic control systems
Published in Mike Tooley, David Wyatt, Aircraft Communications and Navigation Systems, 2017
CPDLC is an air/ground datalink application which enables the exchange of datalink messages between controllers and pilots, thereby complementing traditional voice communications. The objective of CPDLC is to improve the safety and efficiency of air traffic management, enabling routine, non-time-critical communications between pilots and controllers. Examples of CPDLC message include:changes SSR code/squawk identchange of communications frequencyATC clearances, e.g. level changes, vectoring, direct routing speed control, etc.

It is also possible that the proactive measures employed in commercial aviation have minimized or even eliminated the differences between the two phases of flight. Airlines around the world have proactively introduced the concept of a sterile cockpit. Below a predefined altitude, in many cases 10,000 feet, all communication exchanges are limited to flight operations. Pilots are provided with information about their destination airport, such as weather and runway direction, through an automated recording known as the Automatic Terminal Information Service (ATIS). Having this information allows pilots to plan ahead, potentially reducing their cognitive load, through the minimization of new information. In addition, using text form communication such as controller-pilot data link communications (CPDLC) also significantly relieves radio frequency congestion (Hah, Willems, & Schulz, 2010). How the sterile cockpit requirement and automated information service impact on communication accuracy remains an area for future research.
