The purpose of Project North was to provide an increase in sector capacity and improve flight efficiency with maintained safety by development and use of MTCD at LFV. System 2000 at Malmö and Stockholm ACCs has been assessed and a number of improvements recommended.
Project North was established, comprising a collaborative effort between Thales, LFV, EUROCONTROL and Think Research, to perform an initial validation of the recommended improvements via real-time simulations.
LFV is acting as the representative of COOPANS which was formed by LFV, IAA and NAVIAIR to organise convergence of their needs and accelerate the upgrades of their respective equipment. This, along with the involvement of FINAVIA, provides an opportunity for the FASTI programme to reach its objective of standardisation and to accelerate the implementation and deployment of controller system support tools, with the support of Thales Air Systems.
Five Swedish controllers participated in a two-week trial which took place in Malmö in September 2008. The goals of the improvements were to improve the accuracy of the trajectories, add flexibility in the MTCD parameterization and remove some clutter caused by nuisance conflicts. The second week of the trials concentrated on investigating a Group Sector Planning concept and working methods- using the MTCD improvements as enablers.
Exercises were performed in two sessions, the first looking at these improvements in normal operations in two sectors; the second session validated these improvements within a concept of a group-sector planner (where a number of sectors are served by a single planner controller).
The software used for the simulations was that of the operational system at Stockholm and Malmö ACCs, upgraded to support the recommended improvements. Although it wasn’t always possible to draw unequivocal conclusions due to some constraints imposed by the simulation environment as well as technical issues both in the introduced functions and in the legacy functions, some important indicators were obtained.
Within the simulation environment, the use of measured ground speed greatly increased the accuracy of the trajectories which in turn lead to appreciably better performance of the MTCD.
The simulation exercises exposed a number of deficiencies in the trialed method of filtering nuisance warnings. These concerned team working issues between the executive controller and planner controller, insufficient support to the executive controller, and over-filtering of planning conflicts. Application of the Group Sector Planner (GSP) concept was considered possible in low to medium traffic levels, providing little coordination with military ATC was needed. Use of a GSP as a manning option was seen as providing a new intermediate step and not as a replacement for the traditional EC/PC manning. Full details of the trial are provided in the Validation Report (pdf). A number of lessons were learnt.
