The FAA reports that NextGen is bringing new benefits to Salt Lake City International Airport (KSLC) through a technology called Data Comm.

Data Comm revolutionizes communications between air traffic controllers and pilots by replacing some traditional voice communications with digital information exchanges, FAA officials explain.
Voice communication is labor intensive, time consuming and can lead to miscommunications known as “talk back, read back” errors, according to FAA officials.
Data Comm, by contrast, enables streamlined, two-way data exchanges between controllers and flight crews for clearances, instructions, advisories, flight crew requests and reports.
By exchanging digital messages, air traffic controllers, pilots and airline operations centers can communicate more clearly and efficiently. Better communication improves controller and pilot productivity, improves safety, can reduce flight delays and can help aircraft fly more direct routes, which saves time and fuel while reducing aviation’s impact on the environment, FAA officials said.
Several U.S. carriers are benefiting from Data Comm capabilities at Salt Lake City, including Southwest, FedEx, UPS, American, Delta and various general aviation operators, FAA officials add.
The FAA began testing Data Comm capabilities and benefits in 2014 at Newark and Memphis with UPS, FedEx and United Airlines, as well as selec international operators.
The FAA started deploying Data Comm in air traffic control towers in the fall of 2015 and aims to have it in more than 50 towers by the end of 2016.
The technology will be installed in air traffic control facilities that manage high altitude traffic beginning in 2019, FAA officials said.
