Mode-S push has been 100 per cent
successful. The technology also enables an
aircraft’s own airborne collision avoidance
system to recognise potential confl icts and
issue a resolution advisory, something EUROCONTROL’s
communications team has also
successfully promoted. Automatic Dependent
Surveillance-Broadcast is an even more
capable technology that is being trialled and
proven, off ering a superior situational picture
and a new capacity for data transfer.
Ground equipment has had to keep pace.
Unlike the mass technology market where
the fact that more than a million mobile
phones are bought every day creates major
economies of scale, ATM technology is
bespoke and must be far more robust than
other communications systems. While ANSPs
have moved some way towards incorporating
commercial off -the-shelf technology in
ATM systems, there’s a limit to how far they
can safely go.
Ultimately, EUROCONTROL is working
towards a digital future in which information
will be networked between fl ight management
systems in aircraft and fl ight-data
processing system computers on the ground
using high-integrity data communications.
The EUROCONTROL European ATM
programme has succeeded in introducing
key operational functions in which the aviation
community can have full confi dence,
including the Controller Pilot Datalink Communications
(CPDLC) system. Under CPDLC,
two-way data is transmitted digitally between
controllers and pilots and is displayed
on screen, reducing controller workload,
leaving radio frequencies free for back-up
and removing the risk of misunderstanding.
CPDLC has been enthusiastically embraced
by pilots and increasing numbers of aircraft
are installing the equipment.
These and many more EUROCONTROL
initiatives introduced in the past 10 years
are the result of complex planning and
consultation procedures involving the
many stakeholders with a vested interest
in ATM. It would have been impressive
enough to keep EUROCONTROL’s
ambitious strategies on track in times
of stability, but the decade has been far
from stable – war in Iraq and Afghanistan,
the SARS virus and Bird Flu, and most
importantly environmental concerns, the
economic cycle and the 9/11 attacks are
just some of the variables that have made
planning diffi cult.
Nonetheless, EUROCONTROL expects that
peak loads of 50,000 aircraft a day will be
handled by Europe’s ATM system by 2020,
and the system’s sustained daily load will
be around 45,000 fl ights on average. The
10 million annual fl ights handled in 2007 will
have risen to around 16 million by 2020, and
the foundations of the ATM system that will
handle that traffi c safely, effi ciently and costeff
ectively have been laid in this decade.

It’s not about time; it’s not about the
weather. It’s about aviation safety and
security as you fly in and out of Uganda.
All issues concerning civil aviation are
handled by the Civil Aviation Authority.
Such issues include, among others,
advice to Government in regard to policy
matters, but most importantly, provision
of air navigation services and managing
the major aerodromes in the country.
The Ugandan airspace is fully covered with
VHF Communication. Airspace surveillance
is by Mode S Radar for Approach Control
and Entebbe International Airport has
developed GNSS Non Precision Approach
Procedures. This is in addition to ILS DME
for landing and SIDS and STARS based on
conventional ground based NAV Aids.
