Sea-Tac Radar 'Ghosts' Prompt Warnings
Dominic Gates writes in The Seattle Times:
After repeated safety warnings from air-traffic controllers, Federal Aviation Administration officials said Tuesday they will upgrade software to combat "ghost" radar images that can confuse the people guiding airplanes to and from Sea-Tac International Airport.More here.
Controllers complain that recurring "false targets" on the radar system sometimes force them to redirect planes to avoid what looks like an impending collision with one of these ghost aircraft.
In one of many reports filed with the FAA since November, National Air Traffic Controllers Association union representative Dan Olsen wrote that the malfunctions were "extremely dangerous and stressful on the controllers. ... Fix the radar before someone is killed."
The FAA, while acknowledging the need for improved software that's scheduled to be installed at month's end, denies there's a safety issue.
