Nearly 1,000 flights at Chicago's busy O'Hare International Airport were delayed Friday morning as part of an "equipment outage" cause by heavy winds, the Federal Aviation Administration confirmed to NBC Chicago. According to NBC 5 reporter Stefan Holt, the outage was impacting the Airport Surface Detection Equipment, of ASDE, which controllers use to monitor positions of planes on the taxiway. The system incorporates GPS to alert if a plane accidentally crosses onto an active runway, Holt said. The outage comes as wind gusting as high as 60 miles-per-hour blow across the Chicago area, with a high wind warning in effect for much of the day. Earlier in the morning, a ground stop was issued at O'Hare Airport due to the winds. #ohare #flights #travel #chicago #weather
