As stated above by Jagohu in Maastricht there are quite a number of situations where it can and is quicker. Specially with certain crews and AO's.
Within Europe the deadline for ANSP's to use CPDLC was the 5th of Feb 2018. And although still many centre's are increasing their CPDLC potential every day there is more and more exposure to crews. For AO's the deadline is the 5th of Feb 2020.
And another benefit it that during the time you are using the frequency to address one particular aircraft you can still address another (or more) aircraft using CPDLC. And it is not limited just to the one controller. Certain tasks can be delegated meaning there are more (lines of) communications possible at the same time vs the use of frequency only. Specially in dense traffic areas the RT time is one of the main bottleneck's in determining the amount of traffic that is acceptable within the airspace.
Another one to consider is the difference in working of ATN and FANS1/A. And the type of connection.
This all can have an impact on how you perceive CPDLC to work or to experience how "quick" it is.
Thanks EDYY. My response to zonoma is applicable here, too. The ability to delegate the sending of CPDLC messages (noting the non time critical rule) could be seen to be a luxury afforded to those ANSPs that use planners/assistants to the primary controller.
And regarding your final point, is not the GOLD sufficiently comprehensive? Cheers
