Benefits of Data Link
5
Strategic Need
To make more efficient use of
communications
To enable air traffic capacity to
be increased
6
The Problem



Controller workload is a bottleneck
At least 1/3 of controller workload is radio.
Voice channel congestion leads to less than
optimal service.
The Solution


supplying a second communication channel
for routine/strategic ATC messages
to reduce the controller’s communication
workload

Objective of LINK 2000+
Co-ordinate the implementation of
 selected air ground data link services for
ATC,
 at a number of ACCs/airports,
 with benefit driven equipage by airlines,
 based on ATN and VDL Mode 2
 from 2000 to 2007
to reduce controller workload…
with a safety benefit


Airline lead initiative
Using Boeing facilities
Allows variation of input
Data sources:
– ACC costs:

CONCLUDING REMARKS
20




Effective VHF spectrum use is a critical
factor in the provision of air traffic
capacity
However, frequency assignment is already
a major problem
There is a need to use the spectrum more
efficiently
The use of data link offers the potential for
better spectrum utilisation
21


Allowing controllers to focus on air traffic
control could significantly increase
capacity
This would lead to improved safety and
reduced delays
