I've heard "blocked" quite a bit while flying. I definitely agree that situational awareness is greatly enhanced by having all of us on the same frequency but things like clearances and amendments to routings could be easier all around and more accurate when presented via text.<br /><br />There's a time and place for both methods of communication.Landisnoreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-37051348137811346712011-05-30T21:43:15.382-04:002011-05-30T21:43:15.382-04:00-- NIce post.

First, they're struggling to find NextGen justifications, so they've added the "datalink" benefit - even though voice comm hasn't been identified as a problem. So it's a bit of hype, a partial solution to a non-existing problem.<br /><br />One interesting point is the FAA won't own the datalink infrastructure - taxpayers will pay ARINC $.05 for each transmission just like with PDC and DATIS. We will be completely relying on ARINC.<br /><br />Second, datalink works - it's been used in the military, etc. But all the tests in Atlantic City confirm that datalink has a time latency (delay) of 3 to 5 seconds.<br /><br />So datalink is absolutely useful for routine transmissions that are not time sensitive - landing info, a routine descent from abeam, etc. Datalink is not usable for ATC when timing is essential - turns to final, etc.<br /><br />Datalink will NOT replace voice, it will supplement voice, and probably reduce voice comms. (And at times, the voice channel is the limiting factor in sector capacity).<br /><br />What datalink might do is overload your sector to the point at which you can't talk to everybody. Think about that for a while.<br /><br />Finally, to take the well-rounded view we should point out that FAA told the airlines years ago that if they'd invest in Mode-S transponders, we'd exchange datalink info. <br /><br />Airlines spent the money, FAA never implemented the change.<br /><br />The impact of Mode-S datalink non-implementation is demonstrated in the TCAS RA manuever in the terminal environment, when the pilot says "we're executing an RA" and the controllers have to wonder what they're doing - the planes are transmitting their manuever on Mode S, it's just that the FAA system isn't listening.<br /><br />And these are the people who are going to deliver datalink? <br /><br />Datalink has benefits, it's great for non-time-sensitive communication, but it's not going to replace voice. It's disingenuous to say that it's a justification for NextGen, which is not retro-compatible and is going to cost many billion$.<br /><br />By the way, excellent blogging, keep it up.<br />PraxisPraxishttp://praxisfound.wordpress.comnoreply@blogger.comtag:blogger.com,1999:blog-1509900465677846838.post-48016664660000453352011-05-28T00:16:51.131-04:002011-05-28T00:16:51.131-04:00At some point, you'll reach saturation where n...At some point, you'll reach saturation where no tools will help you manage traffic. Wouldn't it be nice if the systems could help automate the repetitive, mundane tasks so you could focus on the exceptions? What happens when there are strategic tools introduced that help change routes four hours from your sector? Do you want to be reading lat/long's in the mic?<br /><br />I am with you on the it will never happen though. Too much politics, too much cost for not enough benefit.
