Upgrade of ATM systems in Sweden September 2018
18 September 14:09
This week there will be an system upgrade in our ATM Systems.
The upgrade will take place during the night between the 19th and 20th of September 2018
for systems in Malmö ATCC and connected TMC´s/TWR's, and the night between 21st and 22nd of
September in Stockholm ATCC and connected TMC´s/TWR's.
When traffic allows, preliminary around 21:30 UTC, we will switch to our fall-back systems and
start the upgrade which will take around 2 hours. During the fall-back system operations it might,
in order to maintain safety, be needed to temporarily decrease our capacity. It is our outmost
goal to limit the impact by monitoring the predicted traffic volumes and only set restrictions if
For the adjacent ATS units the system upgrade means no related technical changes or changes of
procedures. Test flight plans will be sent to certain ATS. When TOPSKY systems
are online again, we will return to normal capacities and operations.
