There are as many as 4,000 controlled flights in Austrian airspace on some days, often at altitudes of 10,000 metres or more. Few would suspect how much painstaking and stressful work on the ground goes into managing these traffic flows safely and efficiently from the moment when an aircrafts engines are started up through to the point when it leaves Austrian airspace. Aided by state-of-the-art technology, our air traffic controllers bring planes into the right airways and ensure that they keep their distance from others. Around the clock, 365 days a year. In 2011 more than 1 million flight movements in Austrian airspace were handled by Austro Control.
