With the right equipment onboard a business aircraft, pilots can get a complete flight plan clearance prior to departure without ever saying a word. "This comes in handy when there's a major weather event rolling through a really congested airport," said Chris Collings of Harris Corp. Currently, controller-pilot data link communications, or CPDLC, is available at 55 of the nation's airports, including Teterboro (TEB) in New Jersey and Westchester County (HPN) in New York, and it will roll out to seven more airports next year.
