7

The ProblemThe 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 SolutionThe Solution supplying a second communication channel for

routine/strategic ATC messages to reduce the controller’s communication workload

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

CONCLUDING REMARKSCONCLUDING REMARKS

21

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

22

Allowing controllers to focus on air traffic control could significantly increase capacity

This would lead to improved safety and reduced delays
