We are once again working on iFACTS as the programme prepares for implementation. This is our third engagement with the programme. Back in 1999 when it was still in its very early R&D phase (as FACTS) it was the first project Directors Rob Waggitt and Conor Mullan worked on when they joined NATS. Think Research became formally involved again in 2004 as leaders for the Core Engine and System Validation. This time around it is to assess the impact of MET data on the trajectory predictions.
