DataComm replaces verbal ATC communications with text messaging, improving efficiency and safety, according to NATCA. Several major airports around the country, including Chicago’s O’Hare and New York’s John F. Kennedy, and 10 large, regional Air Route Traffic Control Centers (ARTCC) have already begun implementing the system. One major issue is a delay in training due to the shutdown. NATCA said much of the millions of dollars that have been spent on training might be wasted because the training will have to be repeated as a result of the shutdown. For example, Chicago’s ARTCC alone spent approximately $1.6 million on DataComm training. Implementation there will likely be pushed back to next year.
