Regional Air Traffic Computer Fails On Second Day

August 31, 1987

NASHUA, N.H. (AP) _ A new computer at the federal Air Traffic Control center experienced a glitch one day after it started operating.

The problem, which prevented the computer from displaying its information on video terminals on Friday, caused a backup system to kick in immediately, a spokeswoman for the Federal Aviation Administration said today.

There was ″absolutely no chaos or misunderstanding involved,″ said Susan Coulter.

The computer started operating Thursday and the backup computer kicked in at 6 p.m. Friday.

The FAA said 18 arrivals and three departures were delayed an average of about 20 minutes at Logan International Airport in Boston. But Coulter said some of the delays may have been because of bad weather rather than the computer problem.

Controllers at the center waited until about midnight, when air traffic diminished, to fix the problem by shutting down and restarting the computer.

The FAA’s technical center is investigating.

The center has experienced two computer shutdowns this summer, both with the old computer. On Aug 21, the system failed three times and on July 28 it failed once.

The center controls flights throughout New England and parts of New York.
