Could a cockpit warning system prevent close calls between planes at US airports?

As a Delta Air Lines jet began roaring down a runway, an air traffic controller at New York’s John F. Kennedy International Airport suddenly blurted out an expletive, then ordered the pilots to stop their takeoff roll. The controller saw an American Airlines plane mistakenly crossing the same runway, into the path of the accelerating Delta jet. JFK is one of only 35 U.S. airports with the equipment to track planes and vehicles on the ground. The system alerted the airport control tower to the danger, possibly saving lives last year. The National Transportation Safety Board and many independent experts say pilots should get warnings without waiting precious seconds to get word from controllers. Just last week, the NTSB recommended that the Federal Aviation Administration collaborate with manufacturers to develop technology for alerting pilots directly. Honeywell International, a conglomerate with a big aerospace business, has been working on such an early-warning system for about 15 years and thinks it is close to a finished product. The company gave a demonstration during a test flight last week. As pilot Joe Duval aimed a Boeing 757 for a runway in Tyler, Texas, a warning appeared on his display and sounded in the cockpit: “Traffic on runway!” The system had detected a business jet that was just appearing as a speck on the runway about a mile away — ground the Boeing would cover in a matter of seconds. Duval tilted the plane’s nose up and pushed the throttle forward into a G-force-inducing climb, safely away from the Dassault Falcon 900 below. Honeywell officials claim their technology would have alerted the Delta pilots who had the January 2023 near-miss at JFK 13 seconds before the air traffic controller screamed the expletive and told them to stop their takeoff. Merely removing the need for a controller to relay the warning from ground-based systems could be critical.<br/>
