Reports on FASTI Implementation.

SYSCO implementation between Copenhagen ACC and Malmö ACC

Introduction

Cross-border tactical screen-to-screen controller coordination, also known as System Supported Coordination (SYSCO) is an enabler for interoperability in ATC. Malmo ACC and Copenhagen ACC achieved a major step in this domain as a first set of SYSCO functions went into operational use between the two units on May 6th 2011.

What has been implemented?

The OLDI messages implemented were COF, MAS, ROF and TIM, providing information about the status of flights being transferred from a sector in one unit to a sector in the other unit. While the COF and the MAS messages do not replace any coordination previously taking place over telephone they are actually providing more situational awareness to the controllers than could first be expected.

In the greater SYSCO perspective the Transfer Messages COF and MAS are natural first candidates for an implementation and can serve as a way to build experience for following implementation(s) of more complex messages and functions.
1. As a COF is sent from Copenhagen the label at Malmö ACC indicates that the controller at Copenhagen ACC has made the transfer2. When the pilot calls in on the frequency the controller at Malmö ACC is making the ‘Assume’ input.3. The label now indicates that the aircraft is assumed. As a MAS is sent this is also indicated in the label at Copenhagen ACC.

Benefits

Claus Skjærbæk, Chief of Operations Copenhagen ACC, states: - “This is a very important first step for Copenhagen. Next we would like to deepen the implementation with Malmö, for example by adding messages for negotiation of level and/or route changes. We are also looking at connecting with other partners who have systems with SYSCO capability, for example MUAC and DFS.”

Michael Bartholdson, Manager Operations ATCC Malmö, says: -“We are very happy to have introduced SYSCO functions with Copenhagen ACC. With NAVIAIR our next objectives are to add the Release Indicator to the COF and exchange “Special Route Processing Requirements”. The latter will support the introduction of Free Route across the whole Danish/Swedish FAB. We are also looking for implementations of REV, MAC and Transfer messages with our German partner DFS and our Polish partner PANSA.”

NAVIAIR Context

For NAVIAIR this was the first SYSCO implementation for Copenhagen ACC, where the DATMAS system, as their version of the Thales EUROCAT system is called, has been in service since spring 2008.

LFV Context

LFV is operating Malmö ACC and Stockholm ACC with a Thales EUROCAT version known in Sweden as System 2000. For internal coordination, between the sectors of each centre, the system mimics the concept and functionally of the full SYSCO concept. This serves as a model when expanding the use of SYSCO with adjacent centres. Copenhagen ACC is the third centre with which Malmö ACC is exchanging the transfer messages COF and MAS.

The LFV SYSCO history

As a FASTI Pioneer LFV has implemented SYSCO over a number of years, starting with COF, MAS, HOP, ROF, TIM and SDM messages between Malmö and Stockholm ACCs in 2005. Upgrades have since taken place, most notably was in May 2009 the COF enhanced with a Release Indicator. This feature is well liked by the controllers and has been found very useful. It has also allowed the removal of a number of ‘standing releases’ from the LoAs. Other messages implemented in Sweden are the BFD and CFD messages, which are used to transmit Activation data to Air Defence. Stockholm-Arlanda TWR and Stockholm ACC exchange the following messages: PAC (with SID indicator), COD, ABI, ACT and MAC. COF, MAS, TIM and ROF messages were implemented between Malmö and Finland (Tampere ACC) in April 2006.

In November 2010 LFV implemented the full exchange of ‘Field 15’ route data between Malmö and Stockholm ACCs according to the “Special Route Processing Requirements” in Annex B of the OLDI Specification. This feature supports the FREE route concept in Sweden FIR (FRAS) as it allows the update of route information between the centers and the automatic creation of an FPL record if an FPL should be missing. Additionally it has allowed a simplification of LoAs by removing the need for “agreed direct routes”.
