Atis - How Does It Work?

Tue Jan 03, 2006 9:19 am

Hi.

Whilst listening to the ATIS via the scanner at the airport last week I wondered how it's working. Is it spoken again and again by an ATC controller or is it a tape? If it's a tape or something similar do they make a new "announcement" every time something (like wind direction) changes? Maybe it's different at every airport or depending on the equipment they have.

By the way - what's ATIS spelled full - Air Traffic Information System?
Thanks for your answers.

Georg.

It's a tape. Every time there is a significant change, then
ATC changes the identifier.
For example, the recording will say " SFO information, Hotel"
When it changes, then it goes to the next letter in the alphabet.
A flight pushing back and contacting ground would say
"XX123, with India".
That was ATC knows that they have the most curent information.
Also, typically the tower will give wind conditions when aircraft are cleared
to land.

It's a looped recording, sometimes spoken by a person but more often in my experience in the Southeast U.S. is a computer-generated voice. They generally change every hour and are identified with a phonetic alphabet letter; for example, an airport may record an ATIS at 1300 Zulu that's information "Tango" and the next would be released at 1400 Zulu and called information "Uniform". Sometimes they're released more often than hourly if there's a special condition or rapidly changing weather.

Here in Nashville its a computer generated voice. Back a few years ago when the Titans were in the Play-offs, it said " Go Titans, Beat Pittsburgh" That was pretty cool.

Honestly, not trying to be mean but did you really think there was any chance that it was a controller sitting there repeating the information over and over again?

It's recorded by a controller and played over and over on a tape. At bigger airports I think they just put the inputs into a computer and a computerized voice reads the report out over and over.

Kinda like when you used to be able to dial a number and get the time..a voice
would say "the time is 10 fifteen and 30 seconds" and update. I used
to think it was someone talking into the phone. Playboy once had a cartoon
showing an old lady with a pile of cigarette butts around here speaking the time
into the phone.

It gives Stephen Hawking something to do when he is over here  Smile

Aside from that, there is also a digital atis that the pilots can receive via ACARS. It shows up as a text message in the cockpit on their ACARS unit. This is much easier, and allows the Pilot flying to not have to worry about monitoring ATC at the same time the Pilot Not Flying gets the radio ATIS.

You might have been listening to an ASOS or AWOS...a little different than an ATIS. An ATIS is the old system and while you still find them, most airports, especially the towered ones, use the ASOS or AWOS afterhours, or the hours when the tower is not being manned...typically 9pm to 6am.

That's interesting. Good to know that the ATIS freqs for CVG A/D are no longer valid.

Thanks for the heads-up. I need to start rescanning on the aviation freqs.
We can agree to disagree.

Not quite. Most of the bigger airports now use an automated ATIS where a Stephen Hawking sound alike broadcasts the information. If you don't believe me, call 617-567-0160 which is the phone number for the BOS ATIS. It gives you the same exact recording broadcast on the ATIS freq of 135.0However, most of the Class C and D airports are still the old ATIS.

773-601-8921 is the phone number for the ATIS at ORD.

After the Cubs lost the NLCS in 2003, the ATIS at ORD said "Go Cubs.... We'll get them next year!" Sadly, the Cubs have not gotten anyone since. HAHA!

And they did, after Nedney faked being roughed on that field goal he shanked. Although I guess the Titans didn't beat Pittsburgh, Nedney's act and the refs buying it did.  Angry

well..this goes back farther than that..late 50s-60's, I believe..from where
I lived (SF Bay Area) you'd dial POPCORN.

Regarding computerized ATIS's:
IIRC, ASOS stands for Automated Surface Observation System, and AWOS stands for Automated Weather Observing Station. Both send computer signals to the ATIS which translates it into the verbage put out on the ATIS. ATC adds the runway info, and as I recall, any local NOTAM information. From that, the computer-voiced ATIS is created, transmitted, and updated as necessary.
