OSYRIS Arrival Manager in operation
at Oslo Gardermoen Airport since 2010
Gardermoen airport in Oslo is the
hub of Norwegian aviation. In 2014,
over 24 million passengers traveled
through Gardermoen, making it the
second busiest airport in the Nordic
countries. To help all passengers
fly comfortably and safely, the
Norwegian Air Navigation Service
Provider (ANSP) Avinor invests heavily
in air traffic control. As a long-term
Harris customer, Avinor installed
Harris’ OSYRIS Arrival Manager
(AMAN) in 2010 to improve arrival
operations at Oslo.
Avinor is a state-owned company,
administered by Norway’s Ministry
of Transport and Communications.
Since 2003, it has been planning,
developing and operating the
Norwegian airport network, which
comprises 46 airports. Air traffic in
Norway is on the rise and Avinor
is constantly looking for ways to
optimize the security and efficiency
levels, while limiting environmentally
harmful emissions and reducing
aircraft noise. In July 2011, the Air
Transport Research Society (ATRS)
named Oslo Europe’s most efficient
airport – an achievement Avinor is
very proud of.
“At the start of 2000 already,
we kicked off a project aimed at
modernizing the airspace to handle
the expected traffic growth,” said
Kristian Pjaaten, Avinor’s AMAN
project manager. “One conclusion
of the initial research was that an
arrival manager at our Air Traffic
Control Center would really optimize
efficiency and safety.” In the
middle of the project, however, air
traffic dropped heavily due to the
tragedies of September 11. When
the modernization plans were
picked up again in 2006, the arrival
management system remained top
of Avinor’s wishlist for Oslo airport.
Pjaaten formed a project team that
included some air traffic controllers
- as they’re best able to define the
requirements - and visited air traffic
control centers around Europe to see
the available solutions in action.
“We’ve been working with the OSYRIS Arrival Manager for over a year now
and we couldn’t miss it for a single day.”

OSYRIS AMAN Delivers Proven Operational Benefits
CUSTOMER TRUST
OPTIMIZE ARRIVAL SEQUENCE
Pjaaten: “The reference visits were key
as we really wanted a proven solution
that had been in use for a while and
we wanted it asap.” During the visits,
Avinor was especially impressed by
Harris’ OSYRIS AMAN system used at
Zurich airport: “The enthusiasm of all the
operators there was one reason for us
to choose Harris. On top of that, we had
good experience using Harris Orthogon
solutions already.”
Oslo’s air traffic controllers have been
working with OSYRIS since November
2010. The system monitors the current
traffic situation and (re-)calculates
trajectory predictions in case of a
mismatch between actual and predicted
positions. Based on this input and the
spacing requirements, OSYRIS plans the
arrival traffic sequence and provides
this as an advice for the controllers.
“It changed our way of working
dramatically,” said Pjaaten, “shifting the
responsibility for delay absorption from
the terminal to the ACC controllers. At
the start, it was pretty difficult to make
that shift. Today, however, we couldn’t
miss the system for a single day. OSYRIS
AMAN really helps us optimize the
arrival sequence. As a result, there are
much less Terminal Management Area
(TMA) delays. An additional benefit is
that the planes no longer have to circle
the airport, waiting to land, which helps
reduce fuel consumption and carbon
dioxide emissions.”
PHASED IMPLEMENTATION
Harris installed the OSYRIS Arrival
Manager both into the simulator and
the operational facility and smoothly
integrated it into the existing Air
Traffic Control system. They also
trained the maintenance engineers.
The training was intensive: each air
traffic controller had completed 30
hours on a simulator before deploying
the new system.“Moreover, as we
knew the impact on procedures and
working methods would be drastic,
we chose a step-by-step approach,”
Pjaaten explained. “OSYRIS was first
used merely as an approach planning
tool: the approach controllers checked
their planning with the advisories from
OSYRIS. Only after a few months was it
used by the Area Control Center (ACC)
sector controllers too.”
INTEGRATED FLOW
MANAGEMENT
The AMAN system helps increase air
traffic flow efficiency in the TMA.
Pjaaten: “AMAN allows us to centralize
the planning of the arrival traffic and
distribute the results to all related sectors
and workstations. This means that all
controllers get an overview of the global
planning, wherever they are, without
the need to call their colleagues all the
time. In this way, misunderstandings
are avoided and our people work more
efficiently.”
INNOVATION:
POINT MERGE SYSTEM
Since April 2011, the Oslo Airport has
been extending its AMAN system with
the Point Merge System (PMS), an
innovative procedure developed by the
EUROCONTROL Experimental Center
(ECC) to merge arrival flows of aircraft.
“Before the merge point (Point Merge)
that aircraft must pass when entering
the last phase of the descent, PMS
determines the order of aircraft, thus
ensuring an efficient and well-organized
landing,” Pjaaten explained. “It really
helps us further improve arrival and
departure operations.” Avinor is the first
Air Navigation Service Provider in the
world to bring the PMS into operation.
Other ANSPs followed Avinor’s
pioneering work. Airspaces over Dublin
and Paris have adopted the PMS and
others are planning to follow suite in the
near future.
