Hey all,
For the U.S. feeds, isn't there a delay of 5 mins enforced by the FAA for ATC radio? I doubt this regulation is in place with Canadian feeds.

Thanks

Not that I know of...I host BDR and compared what someone said and then brought up the feed and it timed in at a 30 or so second delay.

I have not heard of a delay of such.  If it was, you would see it enforced a lot more.

Yeah thats true and the FAA would have taken down this site had that been strongly enforced. However I saw the regulation info it on this site: http://www.atcmonitor.com/ which has live ATC audio of the Atlanta, Georgia Airport.  And also why there is a 30 second delay between the feed and what someone said?

Thought the 5 min regulation was for any type of radar image feed.

Not that our Gov't isn't capable of coming up with senseless regulations and laws   wink  
    I can't understand why there would be a delay requirement. If homeland security was the issue. All the baddies would have to do is monitor a scanner live or get a aviation radio. Or just sit along the flight path and watch.

Rahul-

There is no such regulation.  I don't know where you get your information or why you're even asking about this.  Live means live (except for the encoding/decoding delay).  And I don't mean to attack you personally (I'm not) but just about every day there seems to be someone writing in panicked about such nonsensical matters.  And you just happened to catch me at exactly the wrong time.  This site's main purpose is to serve as a source of training for existing and would-be pilots, to better their communication skills.  Some folks use it as a source of entertainment, and that's fine too.

Some people just seem to think that because they can hear pilots and air traffic controllers talking that it's a "security issue."  What is that issue?  Nobody can ever seem to articulate it.  You know why?  It doesn't exist.

For those out there who suffer from this afflication...stop sitting around fearing every move you make in society.  If you know you're not doing anything wrong, then stand by your convictions and move on with your life.

Sorry to have to use this thread to vent, Rahul.  Again, this is not directed at you per se.

Hope you enjoy listening.

Best,
Dave

If there was some type of "security issue" ATC chatter would be broadcasted on some sort of trunked-digital-encoded frequency that would be almost impossible to crack into. Not on VHF where anyone with a scanner can receive it.

Haha that is true, Robin, I forgot to consider that anyone can pick this up with a scanner live.

And of course kudos to Dave, you really said it right and its ok I don't
feel you are attacking me personally, I think you're 100% right. I listen to it as a source of entertainment (isn't it really nice that almost all the pilots wish the ATC controllers good night?). I love the part about you saying "if you know you're not doing anything wrong, then stand by your convictions and move on with your life." I think every north american today should believe in that.

Btw I got this information from www.atcmonitor.com where it states at the bottom of the page, "* Audio and Video is delayed about 5 minutes in accordance with United States Federal Regulations.  "

Anyways thanks for clearing it up hehe.. I want to thank you dave and everyone else who's helping for this awesome service!!

Hi,

Just to let you know......
I experience a 40 seconds delay.
I tested with a friend, he heard my log 40 seconds later.

I believe the original poster got the notion of a delay from the live flight tracking in applications such as Flight Explorer. I have a subscription to their Personal Edition and there's what seems like a 5-minute delay between what I see and what I hear on LiveATC. I do remember reading that a delay in flight data was implemented for security reasons.

This is true in the case of radar data (and I believe it is 10 minutes).  I know of no such restriction on radio communications.  The only delay we have here is about 5-10 seconds (combined encoder and feed transmission/buffering latency).

Milwaukee's delay has an average delay of 18.7 seconds.

I'm not sure what a "lock off" is, but there is no delay between ATC/pilots and the scanner the ydelay is created do to encoding, transmition to the servers, recoding, and then decoding and playing on your end.
