covers low-cost technology like the
millimetre wave sensors installed at
Frankfurt-Hahn and London-Luton
airports. Two airports are likely to
participate starting in 2008. Other trials
will demonstrate automated detection of
debris on the runway, vehicle navigation
systems and other developments to
A-SMGCS systems and procedures. These
trials will involve a number of airports
including Frankfurt, Leipzig, Heathrow
and Bordeaux, with additional airports
becoming involved in the future.
“The current ICAO [International Civil
Aviation Organisation] recommendations
only focus on SMR [Safety Monitoring
Report],” explains Paul Adamson, Airport
Surface Management and Safety project
manager for EUROCONTROL. “There

may be other technologies that fit the bill.
We hope to develop an operational
concept for a basic surveillance
environment that is not as complex as
A-SMGCS, that fulfils the requirements of
the ICAO recommendations and satisfies
the needs of smaller airports.”
The project is also intending to
establish a steering group, involving
representatives from EUROCONTROL,
the Federal Aviation Administration
(FAA) and key stakeholders, in 2008.
“We have set up a roadmap for a full set
of safety nets for the airport surface. We
are coordinating with the FAA and
aircraft manufacturers to build a common
picture. With everything we do,
ultimately we have our eye on ICAO, and
as systems become more complex, the
global aspect becomes more important.”
Among coordinated initiatives, the
project is looking for common procedures
for use with A-SMGCS tools in low
visibility. Also, FAA trials at Dallas Ft
Worth are testing the use of automatic
status lights to warn of infringements, so
when a warning is delivered to a
controller, it is also communicated to the
pilot via in-pavement lights. The work
builds on the set of operational concepts
and procedures delivered to ICAO under
the first Airport Operations Programme in
2006 and similar trials will be undertaken
in Europe.
IFATCA calls for red stop bars to be in
operation everywhere. The Federation also
recommends that they be operated from
the tower. They should always be
switched off once an aircraft is cleared
to pass. “At some airports there are no
stop bars, at others they just stay on red
all the time. How can you teach a pilot
never to cross red stop bars when some
airports authorise crossing them?”
asks Weidemann.
The very recent introduction of
electronic flight information in some
towers, relieving controllers of some
routine tasks, also offers potential to
improve procedures in a basic A-SMGCS
environment. Automatic conflict detection
can help to identify inconsistencies, and
could buy a few seconds more warning
time for the controller.
“The data shows 50 per cent of
incursions are due to a breakdown in
communication between the pilot and
controller, or vehicle driver and
controller,” adds Paul Wilson, head of
EUROCONTROL’s Airport Operations
Business Division. “Ultimately, now what
we are looking for are technology-based
safety nets. High integrity, high fidelity
safety nets which will stop an accident
happening. The present process will not
do this. You cannot resolve a conflict in
ten seconds.”
Wilson identifies two main areas of
technology. Positional awareness is the
first, where even simple navigation devices
can play a part in preventing incursions in
poor weather conditions. Secondly,
surveillance systems that monitor surface
movement can issue an alarm that
prompts avoiding action. Wilson would
like to see this warning go straight to the
