Radio Scanner On An Airliner

Mon Feb 26, 2007 9:30 am

Just wondering if it is ok or not to bring a scanner on board to listen to while in flight. I can't imagaine it being a big deal, specifially for AS, any one know?

Every airline I've been on lately forbids it, along with FM radios. (Southwest/ATA/Delta/AA/Contential). I wonder if it's more of a liability issue than a interference issue.

Speaking of other devices that recieve signals, I know GPS devices are allowed on Southwest, which I found odd. I don't think they are allowed on AA/Delta.

Likewise, every airline I can remember recently has forbidden radios/portable televisions, but Continental explicitly states that one-way pagers may be used to receive pages at any time... I really don't get the difference between a 1-way pager or GPS unit and a portable radio, but hey....

To the original poster: If nothing else, you could put it in your carryon and ask politely when you boarded if it would be OK... This would also probably go a long way twoards avoiding having a FA flip out on you and accuse you of being a terrorist or whatever.

Many devices that are supposed to be passive (i.e. receive only) are noisy devices in terms of EMI. Cheap radios/receivers probably fall into that category. GPS receivers probably don't as long as they're on, but in receive mode, they use a LNA to amplify the weak GPS signals. Because of the antenna radiation patterns, many high-end GPS devices require them to be at least 1 m away from another GPS receiver's antenna. This may be a reason for the airlines keeping the GPS units off (with the overall reason being security).

It's practically easier to just have a blanket rule that bans all devices with an antenna than trying to explain to a passenger that this particular device is forbidden.

I brought one on a YX flight once and A) It really doesnt work to well, and B) the flight attendent saw me with it and freaked out and made me go to talk to the pilots about it after we had landed. They said it doesnt hurt anything, but they are still not an approved item.

Bringing a scanner onboard a commercial aircraft is as acceptable as bringing your pet rat to McDonalds to have lunch with you. You might not see anything wrong with it, but it sure freaks out the staff and other patrons.

I've used my GPS on flights a few times. This link gives a list of airlines that approve/disapprove:

http://gpsinformation.net/airgps/airgps.htm

Once while waiting to board a USAirways flight, the pilot was hanging around the boarding area so I asked him if it would be ok; he said sure if I waited until they announce electronics can be used.

You do have to hold it up near the window to get a signal, and it takes a while to lock in, but it's cool to see where you are, speed and altitude, as well as the ETA.

1) You're at the mercy of El Capitan (meaning, if you draw a captain who doesn't like it, channel 9 goes silent  Wink )
2) How can you tune ATIS (or any other desired frequency en-route) that is different than the frequency which is patched through on Channel 9?

Of course, having a chart out while en-route would draw just as much suspicion as having a radio receiver or transceiver out...

I do agree with previous posts, many cheaply made scanners/receivers do put out out-of-band "birdies", which is why there is a blanket ban on most radio receiver equipment.

Personal GPS must remain off on airliners because the way they work which is similar in principal to radar or sonar with signal bounce back, that is how you maintain an up to the minute location and that signal can give a ghost on the A/C GPS. As for the Transceiver it is not allowed as it can be used to talk to the flight deck and interfere with radio Com's. intentionally or not.
The radio is not to do with interference it is to do with other passenger comfort as alot of people don't seem to know when the volume is up high enough as to be heard by all around them and the ICE is set up so the volume can't reach the annoyance level

Actually they are passive radio receivers. They work by calculating the times it takes to receive signals from the satellites. A handheld GPS emits minimal RF....

I've found that after I get a position fix, you can move it away from the window a bit, not too far, and it still works....

Question for the pilots or other experts... When I've used it on the plane at cruising altitude, the altitude on the GPS would show 35,010 or 32,010, or similar. Does the altimeter on the plane show the altitude of the bottom of the plane? It looked to me like we were cruising at 35,000 and I was 10 feet high up in the plane.

No.... there are just veriables in those numbers the higher up you go. At 1000ft an altimeter my be only 1ft off....at 10,000ft it may be 10ft off.....and so forth. That is why with the advent of RVSM it is so critical that the planes stay within tolerance.

I got my PPL long after the FCC radio operator permit requirement for pilots...I think an FCC station license was still required for the aircraft (when ARROW still had two R's  Wink ). The ABQ guys (IIRC, "Huntleigh Security") didn't say anything about licensure, but I could have whipped out my FCC Technician Class Amateur radio license  Wink [which still doesn't license one for air band, but nonetheless...] Heck, as far as I know, the only license needed to use air band anymore is for a base station permit. However, the FAA could sick the FCC on you if you start transmitting without any apparent aircraft-related purpose...

Thats why you have earphones that you plug into the unit so no one can hear them.

I remember a few years ago, pre 9-11 I had a radio on board with me. I did turn it on in flight, and hid it, and used a speaker hidden in my pillow so that no one would notice. One problem was, I could only hear the pilots talking, I couldn't pick up any of the ATC people.

Anyways, the regs also say that no one can operate portable electronic devices below 10,000 feet. If you go to youtube, you will find lots of videos from passenger seats of takeoffs and landings, which would supposedly violate that rule as well.

Actually it's because at FL180 and above, aircraft altimiters are no longer set to show true altitude, they are set to show pressure altitude. 35,000 feet on the altimiter is very rarely going to be exactly 35,000 MSL. With GPS, it will show you through triangulation, true altitude.

I can echo that, I used a receiver on a domestic flight in India, and within a few minutes after take off I lost ATC completely, and could hear only the pilot. In hindsight, it was kind of a waste lugging it on board, but it was well worth it when on the ground waiting for boarding!

Well, not the reason, there are exceptions are devices that emit or receive radio signals. If it was to do with passenger comfort and volume, then no MP3 players, ipods, cd players would be allowed ... which they are in cruise flight. We have things called earphones. They are disallowed because they receive radio signals.

The bottom line is that hand-held scanners cannot be used on almost every airline ... in the USA they are specifically prohibited at all times.

Actually they are passive radio receivers. They work by calculating the times it takes to receive signals from the satellites. A handheld GPS emits minimal RF....

Passive (non-broadcasting) receivers/detectors employ various forms of demodulation, some of which involve generating a reference signal. The signal isn't meant to be broadcast, but a poorly designed receiver can leak and generate radio interference. Generally, an FCC-approved device will meet the emission standards mandated for that type of device. The infamous radar-detector-detector used by police to catch people with radar detectors work by detecting the leaking reference signal generated by the detector.

Yep -- I definitely didn't mean to sound like a nit-picker -- GPS receivers definitely don't broadcast -- just meant to point out that with any type of (passive) receiver, there is still concern with the possibility of some leakage. Well-designed, well-built, well-maintained equipment should pose little or no risk.

Just checking. There's plenty of competition for that role.  Smile

Another issue is that most radios generate their own frequencies/RF as part of the radio receiver (think PLL or super heterodyne). Some of the really cheap models or broken units may spew this RF out and several aviation bands are just above the FM band.

Since your cheap FM toy is really close the plane's antenna and the ATC/Ground Nav is far away, not much noise could cause significant interference.

Note the bad cheap toy FM receiver is typically picking up to 50,000 W ground FM stations typically up to 30 miles away, so some internal interference may be acceptable. The ATC transmitter is going to be much weaker so interference is a bigger issue.

Now 99.99%+ of FM receivers are OK, but if even 1 flight has bad interference problems will not be good.



I think the GPS units are better since the GPS signals are pretty damn weak. So if a bad GPS receiver spewed interfering RF, it would ruin its own reception.

Actually they are passive radio receivers. They work by calculating the times it takes to receive signals from the satellites. A handheld GPS emits minimal RF....

Passive (non-broadcasting) receivers/detectors employ various forms of demodulation, some of which involve generating a reference signal. The signal isn't meant to be broadcast, but a poorly designed receiver can leak and generate radio interference. Generally, an FCC-approved device will meet the emission standards mandated for that type of device. The infamous radar-detector-detector used by police to catch people with radar detectors work by detecting the leaking reference signal generated by the detector.

I was trying to acknowledge that even though it's passive (non-transmitting), a GPS may cause interference through emissions. I probably should have clarified that rather than using the term "minimal RF." I agree that all such devices may cause interference; my point was that the amount of interference created by a handheld GPS is usually very small.
The first thing we do, let's kill all the lawyers.

1) You're at the mercy of El Capitan (meaning, if you draw a captain who doesn't like it, channel 9 goes silent )

In the last year, I've probably flown 70 or so segments on UA and only twice have we not had Ch 9. In fact most of the time, either the F/A or one of the pilots makes mention that real-time ATC communitcations will be available on Ch 9.

Some people were talking about UA channel 9. It had XM radio on instead. I was really looking forward to the conversations, but I didn't get that chance.

Seriously? I've always thought about flying UA for Channel 9 but never do as I thought that most of the time they didn't turn it on! I may reconsider now!  Smile

Quick question - does it just work off the VHF radios (Com 1) or does it link with HF too for transatlantic flights?

I have an Amateur Radio License

So what...? Your still in direct violation of the Federal Regulation.

I concur. I hold an Advanced Class license, but that's governed by the FCC Part 97 regs, NOT the Federal Aviation Regs for Part 121/135 air carrier operations. You of all people should understand what type of noise a local oscillator in a receiver creates. And if you don't, then maybe you better turn your ham license back in.

What was the last maintenance you performed on your RF modulators?  Wink

Without testing with a calibrated RF signal generator and receiver in a RF "clean room", you will never know just what interference your particular unit could be causing. This goes for CD players too... IMHO, in light of the availability of flash drive MP3 players, CD players should be banned. But then laptops with CD/DVD drives would have to be banned too, and airlines don't want to tick off their business pax...

Yep -- no argument here -- in the case of "well maintained" consumer equipment, I meant "not abused" -- but that does not guarantee proper operation. About the only way restrictions would tighten is if an "incident" could be tied to some passenger's device.
