An optimal airport arrival scheduling algorithm, which works within a hierarchical structure, is presented. This structure consists of schedulers at multiple points along the route. Schedulers are linked through acceptance rate constraints, passed up from downstream metering points. The innovation in this algorithm that these constraints computed by using an Eulerian model-based optimization scheme. In scheme aggregate airspace model derived online. Optimization based on predictions used to...

NASA's aviation research envisions future concepts for air transportation that will significantly expand the current nature of airspace and vehicle management with an increasing reliance on autonomy technologies. Indeed, increased technologies is a key enabler these concepts. Artificial Intelligence (AI) algorithms, which are at heart emerging technologies, generally perceived as black boxes whose decisions result complex rules learned on-the-fly. Unless explained in human understandable...

Aircraft are often required to delay their landing/arrival time at an airport when they approaching the terminal radar approach control (TRACON) area, due capacity constraints. In regions like Northeast (NE) corridor of US sectors small, with shorter controllable time, and these areas involve very complex traffic flows. Hence, many needed absorb delays aircraft have be delayed far away from airport. Over long distances, ability accurately predict trajectories is not good enough compute...
