WSSS $300 Million Thales Lorads 3 ATC "software glitch" delayed flights on Monday 25 Nov 2013.

Minor software glitch triggers flight delays at Changi Airport

November 28, 2013 - 12:50am


A “minor software glitch” in a new radar system led to flights being delayed from taking off or landing at Changi Airport on Monday morning.

The Long Range Radar Display System (Lorads) III, which went live only last month, is an upgrade from the previous air traffic control system and is designed to be able to handle a higher volume of traffic.

A Civil Aviation Authority of Singapore spokesman said the glitch, which happened at 10.50am, “resulted in some flight delays”.

By 1pm, the system was up and running as usual again, the spokesman added.

A check on the Changi Airport flight status website showed that there were six flights with delayed take-offs during this period.

The delays ranged from 50 minutes to two hours. Another 10 arriving flights landed between 30 and 45 minutes later than scheduled.
