Potential benefits of deploying a ground based augmentation system (GBAS) at Stockhom Arlanda airport

Projekt:

GBAS inflygningar på Arlanda, en förstudie

Sammanfattning:
This report is part of a pre-project study to investigate the possible benefits and
the road to implementation for GBAS operations at Stockholm Arlanda Airport.
The report was created jointly by Swedavia, Indra Navia, LFV and Novair. The
project members have extensive competence in the areas of airport operations, Air
Traffic Control, flight operations, environmental issues, international legislation
and national regulations as well as technical aspects of the GBAS system.
The study describes how GBAS functions and how GBAS operations relate to
current operations. It describes a number of different applications of GBAS that
can be used to improve air traffic management. A number of similar efforts in
Europe and the USA are described. It goes on to explain how GBAS operations
can be approved and implemented on a generic level.
A site where it is feasible to position a GBAS ground station at Stockholm
Arlanda Airport has been identified and an implementation project to progress
towards implementations has been examined. The study proposes that a GBAS
installation be implemented at Stockholm Arlanda Airport in a stepwise manner in
order to provide full GBAS operations at the airport which fully exploit the
potential benefits identified in this report.
The most promising GBAS benefits that can be expected for Stockholm Arlanda
Airport are primarily those that can reduce noise in specific areas using curved
approaches, variable approach angles and/or multiple runway aiming points.
From an ATC perspective it is deemed feasible to commence GBAS validation
flights during periods of low traffic intensity in the coming years. However,
performing curved operation in combination with GBAS in higher traffic
intensity, mixed with traffic using straight-in approaches will be challenging.
Airline operators find that an implementation of GBAS approach procedures and
even more advanced GBAS procedures at Stockholm Arlanda Airport can be
considered feasible, valuable and necessary. They see that the limiting factor will
be the aircraft equipage rate which is nevertheless assumed to increase if
incentives are clearly visible.
GBAS technology is still under development and the market is still to be
considered as immature. However, through testing and studies in the framework
of SESAR, GBAS technology has shown the capability to also provide a number
of operational benefits which are well worth further investigation.
