Limitations of Subliminal Control in Air Traffic Management


G. Chaloulos, J. Lygeros

International Conference on Research in Air Transportation (ICRAT), Fairfax, Virginia

In this talk we introduce an air traffic control concept under the name of Subliminal Control. In this approach, an automated system, commanding minor speed adjustments imperceptible by the Air Traffic Controller, tries to keep the Air Traffic Controller’s risk perception low, emulating a “lucky traffic”. In this paper, we investigate the limits of this air traffic control approach. We test a proposed subliminal controller against several encounter geometries for level flights. A stochastic environment using wind forecast uncertainties is used for this purpose. The results demonstrate the cases where subliminal control can potentially reduce the workload of the ATC.
