Johannesburg - The Air Traffic and Navigation Services (ATNS) company of SA had a good year financially, it said on Tuesday."The past year continued to be a good one for the company, in financial terms," the office of acting chief executive Thabani Mthiyane said in a statement."ATNS budgeted R82m and achieved R209m net profit after tax."The company spent less than expected because it re-prioritised a number of projects.There was a 10% increase in turnover, from R1.05bn to R1.16bn, and a saving of 6% on operating costs.The stronger rand helped financially because of commodities bought in US dollars. The company reduced the number of consultants.In the next two years, ATNS planned a major systems upgrade for its South African air traffic system, to the tune of R500m. The system now in use was installed in 2002.In October last year, the company began using a 3D simulator for training."With this new device ATNS is able to recreate any airport terrain in the world and simulate virtually any flight conditions or operational difficulties, to prepare candidates for the real thing."ATNS provides all of South Africa's air traffic, navigation, training and associated needs. It controls 10% of the world's airspace. *Follow Fin24 on Twitter, Facebook, Google+ and Pinterest.
