The Air Traffic Navigation Services (ATNS) is making progress on four workstreams to fix issues that were identified at the State-owned entity and causing problems at airports, Transport Minister Barbara Creecy said during a March 17 media briefing on the overhaul of the ATNS. The briefing followed the precautionary suspension of ATNS CEO Nozipho Mdawe to investigate if she failed to properly fulfil her duties and Creecy's meeting with the ATNS board and management on March 17.
