ATIS, or Automatic Terminal Information Service, was originally conceived as a time-saving method of disseminating critical, predominately weather-related, information to aircraft interested in arriving or departing from a particular airport.
It’s basically a short recorded message which plays on an endless loop. Remember the days when you had to call a movie theater and listen to a recording to figure out the show times for each film? That’s what we’re talking about here. Pilots listen to the ATIS recording before departing or arriving at an airport in order to learn the wind direction, sky condition, altimeter setting (aka barometric pressure), and runway(s) in use.
ATIS is only available at airports which have an operating control tower. The recording is typically updated every hour and is labeled with a letter. The first ATIS of the day is called “Alpha”. The next hour, when they update it with the current information, it is referred to as “Bravo”. The following hour it becomes “Charlie”. If the weather changes significantly in less than an hour, it will receive a ‘special’ update. When the weather is poor or changing rapidly, updates can happen every few minutes.
In theory, ATIS makes sense. Why require a tower controller to report the weather to every aircraft which contacts them? It’s much easier to simply record that information, and allow the pilot to obtain it on their own time.
Sadly, as with most things in which the government is involved, over time the ATIS broadcasts tend to become bloated with more and more information. The worst example I’ve seen is my home field of John Wayne Airport. If you want to hear it yourself, call (714) 546-2279. I just transcribed the current recording:
John Wayne Airport information Juliet, 1626 Zulu special, wind calm, visibility one-zero, ceiling one thousand five hundred overcast, temperature one eight, dewpoint one three, altimeter two niner niner zero, ILS runway one nine right approach in use, landing and departing runways one niner right and one niner left, caution for a crane three hundred forty one feet MSL two thousand feet right of runway one niner right and a crane one hundred twenty seven feet MSL southwest runway one nine right adjacent to the tower, check Notice to Airmen for any impacts to instrument approach procedures, airport surface detection equipment in use, pilots should operate transponder including mode charlie on all runways and taxiways, all aircraft read back all taxi and hold short instructions, all departing general aviation aircraft contact clearance delivery prior to taxi, IFR aircraft use frequency one one eight point zero, VFR traffic use frequency one two one point eight five, advise on initial contact you have information Juliet.
I’m surprised there’s nothing on there about using caution for birds in the vicinity of the airport. That’s usually part of the ATIS as well.
Anyway, imagine a slow, computerized voice reading all that. Now imagine that it’s happening while you’re operating an aircraft like a spiffy new turbo-normalized Cirrus SR-22 which rents for $350 an hour. The ATIS at John Wayne is currently one minute and thirty seconds long, which means every time you listen to it, it costs $8.75 if the engine is idling.
Oh — did you miss part of it? Then listen to it again. Now the tab is up to $17.50. I’ve had students who had to listen to it three or four times in order to get all the information. And we wonder why flying is so expensive!
It’s even worse if you’re in the air. Sure, you’re already running the engine anyway so it’s not costing you any extra money. But when airborne, your other resources — namely time and attention — are heavily taxed. Your time and attention are critical because you need to be doing other things when you’re approaching an airport. Talking to controllers, running checklists, configuring the aircraft, descending, slowing down, watching for traffic, looking for the airport, and so on. If you’re an instructor, you need to be teaching — and this all happens at a critical transition phase where instruction is important. The length of the ATIS gets in the way of all that.
If you’re flying in instrument conditions, the ATIS is an even bigger obstacle. Not only is the information contained in the ATIS more important to you, but instrument approaches are very high workload environments for the pilot, especially near an airport like John Wayne. The communication frequencies are congested because everyone’s IFR, the controllers are busy, you can least afford to miss a traffic call, you’re being vectored, and are probably setting up radios, GPS, and briefing the approach. This is exactly the wrong time to take a minute and a half out of your day to listen to a pedantic recording with a lot of information you don’t need. If the TRACON controllers were smart, they’d petition to have ATIS broadcasts reduced to the absolute minimum. I guarantee they’d get better responses on the radio from pilots, especially low-time IFR guys and instrument students.
Speaking of controllers, at smaller airports the ATIS is often recorded by a human voice. The problem there is that the recording is made by the tower controller. Yeah, the same guy who’s controlling traffic. If he’s busy and/or there’s a lot of data to put on the recording, he will tend to talk very fast, because the longer they are occupied with making that recording, the longer that guy’s air traffic is not being dealt with. That makes the ATIS hard to understand. Around here, El Monte is well-known for suffering from this issue.
Over time, pilots have developed ways of mitigating the time- and money-sucking effects of a long ATIS:
- listen via phone before engine start
- listen via handheld radio before engine start
- listen to only part of the ATIS
- don’t listen to it at all
- don’t listen to it, but tell the controller you did
- ask the controller to read you the weather portion
- listen to two frequencies at the same time
I have seen these and many other strategies used by pilots. Each of these shortcuts has a drawback. Some are safety issues, others are simply inconvenient. But the larger issue is that these shortcuts shouldn’t be needed at all. The ATIS is simply too long.
Heck, even if you listen to the ATIS, sometimes you haven’t listened to it. How is that possible? Let’s say you just dedicated 90 seconds to listening to the recording (although between asking for a frequency change, tuning radios, etc it’s probably closer to two minutes). You report that you have “information Alpha”. The controller says that information Bravo just came out, so report when you have information Bravo. Great. Now you have to listen to it again. Oh, probably only the weather portion changed and everything else is the same. But what if it’s not? Suppose a navaid is now out of commission, or runway lighting is affected, or there’s a disabled aircraft on a taxiway? I’ve seen all those things happen just at John Wayne.
Yeah, ATIS is a problem. The solution, however, is elegantly simple: shorten it. Not just a little, I mean cut that thing down to the bone. Absolutely vital information only. In most cases, that means weather. Take a look at the bolded portion of the ATIS transcription. If I were king of the world, that’s all you’d hear.
This is not an answer requiring a Ph.D, so you might wonder why someone at the FAA hasn’t seen the light and taken action. First of all, the FAA doesn’t care how much money or time you waste on the ground. If they did… well, let’s just say aviation would be a much different place. Second, as a large government agency, there is a fair bit of “CYA” thinking. If it’s on the ATIS, then the pilot as been advised of it and the FAA is not responsible for non-disclosure. You hit a bird on departure? “Hey we told you about the birds”. Third, the controllers don’t have to listen to the ATIS a dozen times a day, so they aren’t aware of the problem. Fourth, controllers are no longer pilots. In the old days, a high percentage of controllers were also pilots. That was a good thing, because they saw every aspect of air traffic from both sides of the coin. Today, very few controllers are active pilots, and it shows. I can readily identify a controller-pilot just by how they talk on the radio.
There is another reason that the ATIS stays as long as it is, and it’s called “D-ATIS”. Digital ATIS is a transcribed, digitally transmitted version of the ATIS audio broadcast, usually accessed on a computer screen in the cockpit. It’s mainly the airliners, business jets, and other big money operators which have access to D-ATIS. They are the ones with the deep pockets and political clout to have complaints about the ATIS addressed. The problem is they don’t have to listen to it! It’s transmitted to a screen and they simply read it at their leisure. The rest of us simply suffer in 90-second-long silence. Try sitting in silence for 90 seconds. It’s a long time. Now imagine you’re traveling three miles a minute over the ground.
I have campaigned to have the ATIS shortened at John Wayne to no avail. I feel strongly that most of the information should be published elsewhere in writing and obtained as part of a preflight briefing. All that junk about the cranes, approach minimums, ASDE, clearance delivery frequencies, birds in the vicinity, etc. belongs elsewhere. Even the portion about the runways in use should be removed. Pilots are already aware of the runway configuration, and once they have the wind direction they should know which runway is in use. Especially at a Class C airport, the TRACON controller is going to be routing pilots toward the runway in use, and they even tell you which runway it is. “Head to Signal Peak for left traffic, runway 19 left…”
Shortening the ATIS would increase efficiency, reduce costs, and improve safety. When something other than weather is added to the ATIS broadcast, it should be because a temporary situation has occurred where vital operational information needs to be disseminated to ALL pilots. Examples:
- stuck mic on the tower frequency, so an alternate is in use
- disabled aircraft on the runway
- runway or taxiway closure (and even then, only until published in a NOTAM)
Reducing non-weather ATIS information to the absolute minimum ensures that the entire recording will be listened to and understood. Critical information will stand out rather than be lost in a stream of unimportant data. And when you miss a piece of the ATIS, you can take comfort in the fact that it will loop around again in 20 seconds, not 90.
So there it is. If you think ATIS is too long at your airport, do something about it. It’s a safety hazard. The longer we stay silent, the longer it’ll get and the longer we’ll stay silent while listening to it. Kind of a vicious circle, isn’t it?

As far as other squawks, check for corrosion from loose sound-deadening pads. The adhesive was known to retain moisture if it came loose from the airframe. I’d also check above the headliner, in the tailcone, and inside the wings for corrosion. None of these airplanes had any corrosion proofing unless they were ordered with the optional sea-plane provisions.
One of the big attractions of the Cirrus is that they come with a safety device known as a Ballistic Recovery System. The BRS is essentially a parachute. The canopy is stored in the aft section of the fuselage, and when it’s activated, a rocket pulls the ‘chute out of the aircraft and frees straps built into the fuselage. The pilot shuts down the engine, and the entire aircraft descends to the ground at a slow enough speed to allow the occupants to walk away unharmed.

Aileron rolls are classically initiated by raising the nose before rolling the wings. This is done to allow for the drop in pitch which inevitably occurs when you bank the wings and lift is redirected horizontally.


Vice President Cheney dropped in on us at John Wayne Airport yesterday. Air Force Two, a Boeing C-32A, arrived shortly after 1:00 p.m., and with it came an armada of police, Secret Service, and spooks that closed down the airport for the balance of the afternoon.

The winds were completely calm today, which made boxing the wake, holding position on tow, 720 degree steep turns, and other such maneuvers quite easy. It was a 180 degree difference from last Sunday, when the winds were blowing so strongly out of the north that after my CFI released the tow rope at 300 AGL, I almost got blown off the airport before the downwind turn could be completed.
Whatever the cause, if you were to talk in private with those of us in general aviation (a group that includes Burt Rutan, Steve Fossett, Richard Branson, all four SS1 test pilots, and just about everyone at every X Prize competitor), the consensus would be that getting the FAA involved is going to slow commercial development of space flight. Just how much depends on how involved the FAA gets. The rate of development will be inversely proportional to the government’s involvement.

I shouldn’t feel bad, because it’s probably not an age thing. I remember the strike well, but for a different reason: I was there. When I moved to Alaska in 1982 to live with some family, my cousin Dave was in working at the Anchorage enroute air traffic control center (aka “Anchorage Center”). The Center controls a lot of the traffic in the Pacific. The next closest Centers are in Seattle and Tokyo. The actual Anchorage Center building is a large windowless structure sitting on the edge of Elmendorf Air Force Base. Even in the early 80′s the equipment had a antiquated feeling–you could almost smell the electronics slowly cooking themselves.
The Saratoga that JFK, Jr. was flying is almost identical to my Cherokee. In fact, just about everything Piper Aircraft has made in the past 35 years has been based on the original Cherokee design. And speaking of the Cherokee, my aircraft’s annual inspection is finally over. It took most of the day to get everything put back together, but around 4:00 p.m. Norm and I fired her up after a careful preflight. The engine runup showed no problems, but we shut down anyway to inspect the inside of the engine compartment. All was well, so we proceeded with a high speed taxi test, and then opened the cowling again to check for any obvious problems before taking to the air. After three or four times around the pattern, Norm had to head out, but I decided to fly over to John Wayne and give the engine a workout to circulate the oil.


It took close to two hours after we landed before I could even think of getting poor Steve to the car–he just couldn’t be moved (even as I write this, several hours later, he’s laying face down on the living room floor; I’m going to start calling him “Bernie”). He did, however, have enough of a sense of humor to ask what I thought of his “Kate Moss after a Thanksgiving dinner” impersonation.
Last night I was cursing myself for scheduling the checkride for Christmas Eve. I had to plan a cross country flight to the San Francisco area, and in a small general aviation aircraft operating under VFR with lots of visual checkpoints, it can get to be an extensive thing. My flight plan was four pages long. Plus I had to be ready for the two hour oral exam and 3+ hours in the plane. If you’ve never seen the Federal Aviation Regulations, it’s a 1,000 page book of rules for pilots, and anything in them is fair game. I had to be able to give a coherent answer to questions on aircraft systems, airspace, regulations, aeromedical factors, aerodynamics, cross country planning, emergency procedures, traffic patterns, weather theory, and demonstrate all those (and more) in the air.
They say that the day a pilot first flies an aircraft alone (“solo”) is something he or she will always remember. Today was my day, and now that it’s over I understand what they mean. Every pilot faces that moment when the CFI has left the aircraft and you’re taxiing back to the runway, excited yet all the while wondering if you’re really going to be able to do this.
