NeoSYS in an actor in the Time Based Project for the realisation of WP2000, Definition of Operational Concept. This assignement made NeoSYS specially cautious of wake vortex phenomena and other hazards that can be encountered as well as engineering the appropriate inovative solutions.
To minimise the potential loss of runway capacity due to weather phenomena NeoSYS has been involved in the definition of time separation criteria that should replace the longitudinal distance separation during marginal weather. These time separation criteria should be now validated through fast time simulations dased on NeoSYS experience in scenario definition and preparation for simulations. We blue printed the scenarios for the operational training course for ATC controllers.NeoSYS can offer specific profiles with pilot or controller background, bringing you operational and technical knowledge.
“Time-Based Separation” project main objective is to investigate the possibilities to compensate any loss of runway arrival capacity happening under strong headwind while maintaining the required level of safety.

An important limiting factor in airport capacity is the wake vortices generated by airborne aircraft. To avoid entering the turbulence of another aircraft during the approach, minimum separation criteria - in terms of longitudinal distances - are applied at all major airports through the use of radar to provide safe separation.

Under strong headwind conditions, several studies show that the current distance separation thresholds are too conservative resulting in a lower runway capacity. Based on this fact, the time based project investigates the replacement of distance by time intervals whilst maintaining the required safety. If time based instead of distance based separations were applied in combination with suitable support systems and the use of appropriate working methods, most of the loss of runway capacity due to wind conditions could be recovered.
