Ensuring the runway operates at optimum capacity contributes to the smooth running of an airport and increases the amount of traffic it can handle. This candidate solution focuses on an integrated runway sequence function to balance arrival flights and departure flights on single runway, dependent runways or parallel runways with the option to balance also flights between parallel runways. This solution enables efficient operations through early planning to support predictability, continuous decent and enhanced runway throughput operations. The functionality of dynamic trajectory-based integrated runway sequence is designed to be combined with other SESAR Solutions, such as wake turbulence re-categorisation and time-based separation.


Efficient use of runway capacity helps to reduce queuing on approach to the airport and on the ground and results in lower fuel consumption and cost to airspace users. Assisted by integrated arrival and departure planning tools, tower and approach controllers can optimise runway configuration and sequencing while maintaining safety and human performance. This solution applies to single and multiple runways, interdependent runway layouts and mixed mode operations.

The concept relies on early and dynamic planning of arrival and departures using trajectory-based integrated runway sequencing. This is achieved using accurate target take-off times (TTOTs) and target landing times (TLDTs) in a look ahead time horizon period of approximately one hour, depending upon local implementation. The integrated runway sequence for arrival flights is linked with airport collaboration decision making (A-CDM) procedures for departures to provide dynamic assistance to controllers.

The integrated runway sequence function calculates an optimised runway sequence including arrival and departure flights linked to the arrival trajectory prediction (to provide estimated landing times) and departure management (based on estimated take-off times). This contributes to increased airport capacity, and leads to more predictable and punctual arrival and departure times as well as fuel efficiency for airspace users.

SESAR JU partners completed a series of validations including two real-time simulations in Geneva and Stockholm-Arlanda airport environments, and a fast-time simulation in Roma-Fiumicino airport environment, to validate improvements in fuel efficiency and airport capacity when using an integrated runway sequence function. The results also showed an improvement in human performance and enhanced situational awareness. The validation proved the concept is mature and delivers improvements in predictability and punctuality in a high-density airport environment. In the next stage, the procedures can be refined locally at airport level with demonstration activities.

The solution is ready for industrialisation and conforms with the EUROCAE standard ED-141 A-CDM technical specifications.
