The EU has agreed to extend the Single European Sky Air Traffic Management Research (SESAR) programme until 2020 and to allocate it a further €500m ($670m) of funding. SESAR, which was set up in 2007 and due to close in December 2016, has been hailed as one of Europe’s most successful public-private partnerships. The research programme into new air traffic management technologies and techniques has already developed remote tower services, toolkits improving safety on runways and the world’s first flight in four dimensions (3D + time). The EU believes that SESAR 2020 will see a further €1bn (£1.3bn) of investment from Eurocontrol and industry. Organisations interested in joining SESAR 2020 will have the opportunity to express their interest this summer and the new programme is expected to launch in 2015.
