August 16, 2015 - The FAA identified a recent
software upgrade at the Leesburg, VA,
high-altitude radar facility as the source of
Saturday’s automation problems. The agency is
working closely with its contractor, Lockheed
Martin Corp., to prevent future occurrences.
Despite the outage, air traffic controllers
safely handled 70 to 88 percent of Saturday’s
scheduled arrivals and departures at the
region’s three major airports by using backup
systems and procedures. The availability rate of
the En Route Automation Modernization (ERAM)
system has been higher than 99.99 percent since
it was completed nationwide earlier this year.
