The FCC has terminated its proposal inquiry to relax cell phone ban laws, but FAA regulations still run the show anyway

In December 2004 the Federal Communications Commission launched an inquiry to rescind or relax its ban on 800MHz-band cellular phones aboard in-flight aircraft.  In addition to lifting the ban, the study also investigated the feasibility of using pico-cells and other technology to boost coverage in-flight communication via mobile devices.

In a release today, the FCC announced it has terminated the 2004 study (PDF).  Some aspects of the study, such as technical solutions to physically allow cellular phones to function on aircraft, were deemed a success.  The FCC states that its advisory arm has conducted extensive research into the hazards of in-flight usages, with potential solutions as well.  These findings will be published by mid-2007.

However, even if the FCC were to reverse its ban, the U.S. Federal Aviation Administration still has a long standing policy prohibiting usage of transmitting electronics in-flight.  While the FCC's in-flight ban is largely credited to air-to-ground interference, the FAA's ban on cell phones is due to the hazard of air-to-air and in-cabin interference.

The FAA's mobile device guidelines at least partially influenced the FCC's decision to abandon its exploratory research.  "The Commission also noted that the Federal Aviation Administration (FAA) prohibits the use of portable electronic devices (PEDs) on airborne aircraft," the FCC stated. "Given the lack of technical information in the record upon which we may base a decision, we have determined at this time that this proceeding should be terminated."

There is still a loophole in the FCC and FAA bans.  Aircraft-specific services, like Connexion, may operate under the spectrums allocated by the two agencies.

Okay so both entities say it's hazardous to operate a cell phone during flight..... and we want to use a cell phone why??

Not sure what the point is here.... the people responsible for the safety of air traffic say it's not safe to use a cell phone during flight.... and the people responsible for cell phone usage say it's not safe to use a cell phone during flight....


Wow what a big waste of time.... how about they do a study finding out ways to make cell phone usage safe... or coming up with an affordable alternative to the $5 per minute phones that are provided... am I the only one here that thinks this is a complete and utter waste of time and money???

No, the FCC isn't saying that it's harmful or not. The purpose of the study is to find that out. Note that the context of "harmful" as far as they are concerned is whether it interferes with cellular systems on the ground. The results of the study is inconclusive but they still are taking the position against use because of the potential for ground interference.

Similarly, the FAA also prohibits use use of cell phones while an aircraft is flying, but the rationale is the potential to affect on board navigation systems. I think there are other studies ongoing to see if this concern is valid.

These studies are being done because a lot of people want to use their cell phones while in flight. While I'm not sure where I stand on aircraft phone use, I think the studies are not a waste of time and money.

These studies are a good thing. I'm a professional pilot, and I can't tell you how many times we've needed information in the air and have had a hard time doing it over the radio only to find that our cell phones work just fine. I've never noticed the slightest blip in our instrumentation, nor should there be since cell phones operate at such a low power compared to our comms radios, nav radios, radar, electronics, generators, and god knows what other EMI generating devices we have on board. I guarantee you no one has ever tested all the different makes and models of microwaves the stewardesses use in all the different combinations of aircraft and avionics to see if they interfere with anything, and those are a hell of a lot more powerful than the even the most powerful cell phone.

When cell phones came along, and this rule came out, I saw a video where a technician took an ILS reciever out of a plane, put it on a test bench, took the cover off, and then was able to generate interference with a cell phone a foot away and transmitting. As soon as he put the cover back on, the interference was eliminated, which is what the cover is designed to do. Essentially, cell phones are "portable transmission devices" which fit into a pre-defined category of things the FAA won't allow.

Rather than think about it or test it, the FAA disallows it, thus proving their necessity in the aviation marketplace. In short, this rule is a fine example of the FAA bureaucratic bullsh!t we in the industry have to deal with every day.

Cellphone frequencies may not be safe on aircrafts currently, but if/when inflight WiFi (aka Connexion) becomes available, VOIP-capable devices are definitely an option..

I know Boeing unplugged Connexion at the end of '06, but something else might pop up.

It's quite funny how Wifi operating at 2.4GHz is completely safe for aircrafts, but cell phones operating at almost the same frequency (e.g. 3G phones use 2.1GHz) are veeeery dangerous...

That's because "dangerous" to them equates to "the service would be poor and calls more likely to be dropped, and the call would be jumping from cell site to cell site too quickly for our nodes to handle and thus might screw up billing." (The billing issue being the part they care most about.)

It's also important to note that cell phones aren't banned from civil aviation where the phone and its signals would be right in the cockpit. The electronics are probably less shielded in the Cessnas and Pipers also. In reality, there's no technical reason not to use cell phones or pagers on board aircraft. It's more human issues.

My own cell phone isn't bad, thankfully, but other people with various models that I've taken flying with me in Cessna's have caused some noise interference on the radio that can't be squelched out.

That's about all I've noticed, though. Then again, some things, like a slight GPS error, VOR or NDB error, or the likes would be impossible to notice in small amounts, but 'small amounts' and a fuzzy radio shouldn't take a plane with a competent pilot out of the sky. I agree, it's a human issue as much as anything, though the fact that it does cause some minor problems may have the FAA erring on the side of caution I suppose.

You may not have known the exact real-world effects of cell phone usage on an aircraft's circuits with a study like this. And different aircraft will undoubtedly have different vulnerabilities.

Why use a cell phone in flight? Why use one at all, ever? Somehow people survived (and even procrated!) before cell phones, but now some people are never without a connection. Look at the folks with those little headsets permanently attached to their heads. So, the world progresses and people begin to feel that there shouldn't be ANYWHERE that they are out of contact. Maybe for business, maybe for personal reasons. Whatever. Time goes on. People want more convenience.

Also, I think the idea was to try to find a way to give consumers the convenience without causing a safety issue. Without an in-depth study, the solution may elude them. What if you could have both inexpensive communications capability and in-flight safety? What if the results had been different? Would the study then have been worth it?

So, even tho the study didn't produce the "happy answer", you needed the study to learn the facts.

Actually, from my reading of the article, the "happy answer" is exactly what the study produced, which is why they finished the study. I think the title is poorly worded because the author failed to understand what the study was actually trying to do and was capable of affecting.

Have any of you thought about a plane full of people yapping away on their cell phones? I for one am glad that cell phones are prohibited on flights. People can survive a few hours without speaking to someone. Also, I don't want someone who can call up a bomb in the luggage compartment. Keep it difficult to make calls on planes.

Cell phone disputes are always funny. Just like... is the glass 1/2 full or 1/2 empty?

Few people mention about having X amount of people yapping on the cell during flight.

I must fly on the wrong airline(s) or at the wrong times because I have yet to have a flight without a constant chatter. Granted, my flights are typically about 3-4 hours at most and on 717's class planes. Some 737's.

A cell phone ban isn't going to stop someone from detonating a bomb with a cell phone.

Just think about it: if a person is willing to blow up the plane that they're on, do you really think that they'll care about breaking a minor rule such as operating a phone while in flight?

Perhaps. But if you were going to detonate a bomb on a plane with a phone, would you get on the plane? And I'm pretty sure all bags are scanned for active electronics signatures. So it's not like you can just put a bomb in a bag with an active receiver. Even if it was in sleep mode, I'd hope bags are scanned throughly enough that the equipment would be picked up.

Also, if you were on the plane, the person sitting next to you or in the row next to you, would kind of notice you messing with your cell phone. Granted it doesn't take long for you to turn on your phone, type in a number, and hit send. All the same, I'd prefer the ban to stay in place.

I don't know what airlines you've been flying on, but nobody's going to stop anyone from opening a cell phone, punching in a number, and hitting talk. They tell everyone to turn off their cell phones, but in reality, you can just leave it on in your pocket. The likelihood of anybody stopping you in time is very small.

Also, they don't scan for active electronics. I put active cell phones and pagers through the machines every time, and I doubt checked bags are different. They check for explosives more than active electronics since active electronics could be a plethora of benign things.

Instead of using a cell phone that may or may not have reception, wouldn't you just use a kitchen timer? That's what they use in Iraq a lot, and it seems to work great there.
