NPR reports that the United States federal government has approved a US$1 billion spending package to "begin modernizing the nation's air traffic control system." If you have Ebsco you can view a more detailed explanation of what those in the know call ADS-B (short for Automatic Dependent Surveillance Broadcast). Wikipedia has a pretty extensive article on the matter as well.I myself will remain skeptical of the claims that by modernization and consequent increases in capacity there will also be an improvement in on-time performance.
