Sydney Airport air traffic control issue expected to cause widespread delays

Chaos as ALL flights at Sydney Airport are grounded due to power outage on the first day of school holidays

Technical issues experienced by Airservices are restored, with some passengers travelling from Brisbane Airport into Sydney now delayed by two-hours due to the backlog.

Sharing update information via Twitter, Sydney Airport said the Airservices system issue had been resolved at approximately 8.40am AEST.

One pilot described the Harbour City's skies as being "like a ghost town" to air traffic control as he came in to land.

As a result, only a limited number of flights were able to land and depart.

FLIGHTS into and out of Wellcamp Airport are unaffected by the current fault that has grounded flights at Sydney airport.

At around 5am, Sydney Airport confirmed there was a "system software failure" which was preventing planes from both taking off and landing.

The airline confirmed the issue with a tweet: "flights are delayed due to an @AirservicesNews system issue".

The fault has now been rectified, and Airservices is now working to resume to normal operations and clear the backlog of flights.

Qantas Airways Ltd, the country's biggest carrier, said in a statement posted on its Website that there were "significant delays at Sydney Airport affecting all airlines" without giving more detail.

The Tourism and Transport Forum, an industry lobby group, seized on the disruption to call for the federal government to provide "further operating flexibility" by increasing the hourly cap on aircraft movements from 80 to at least 85.
