Other means of communication such as Controller to Pilot Datalink Communications (CPDLC) may present challenges if used in airspace with many time-critical clearances and communications. The current systems are too limited to deal with environments in which the majority of clearances are time-critical, mainly because of response times. It is therefore very likely that RTF communications will be the sole or major means of communications in many areas in the world.
IFATCA Policy is:If a controller is providing ATS for two or more areas, the relevant channels shall be located on the Controller Working Position being used. If more than one RTF channel is being used, then suitable ‘retransmit’ facilities shall be provided to enable all users to receive all transmissions. The ability to enable or disable ‘retransmit’ facilities should be provided. Future systems should include technology that warns the controller in the event of a crossed transmission. Independent backup equipment should be provided. Communications with aircraft should only be undertaken within the Designated Operational Coverage (DOC) for the frequency being used. Voice switch systems shall include facilities to:
IFATCA recognises the need for, and supports the reduction of voice communication workload of controllers. However simply omitting items without alternative methods of accomplishing essential checks compromises safety. |
