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                                        7
LINK 2000+ Programme




                       8
  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
                                               9
             Functional Scope
   DLIC     Establish the application communication
   ACM      Transfer flights between sectors/centres
   ACL      Request/give ATC clearances
   AMC      Microphone stuck?
   CAP      Show flight instruments to controller
   FLIPCY   Compare FMS and FDP flight plans
   DCL      Request/give departure clearances
   DSC      Request/give oceanic/STAR clearances
   D-ATIS   Request/give terminal information

     Supplementing voice for routine/strategic messages

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
