US-based Raytheon recently won contract to upgrade the Air Traffic Control (ATC) software

Several flights were affected at the Mumbai airport in the wee hours on Sunday as the new Air Traffic Control software undergoing test run failed. 

"Four departures from Mumbai were delayed by 15-20 minutes and no arrivals were affected. The Auto Track III, the upgraded system went into 'degraded mode of operation' from 3.10 AM to 5 AM," Joint General Manager, Air Traffic Control (Mumbai), G Dasgupta said.

"By 5 AM the engineers were called in and the system was switched back to Auto Track II, the previously running system. At the Mumbai airport the Auto Track-III is on trail since a month. Now the airport is back to normal running on the Auto Track-III," he said.

US-based Raytheon had recently won the contract to upgrade the Air Traffic Control software and Delhi and Mumbai airports are currently in the process of migrating to the new or upgraded system.

Earlier, airport sources had said that around 30 flights were affected but ATC officials claimed that since it was a lean hour being a Sunday morning, the number of flights impacted was limited.

Also, the airport was shut down at that time for half-an-hour for regular cleaning and maintenance purposes of the runway.
