Not all safety critical avionics are in the forward cabin
Not all safety critical avionics are in the forward cabin and much are kept in the Aft sections. Pilots (that are not software/electrical engineers) know little about avionics from a design/EMI standpoint.

Oddly, I find the quality of many basic consumer electronics better than some top-end avionics electronics. Why? Volume. Apple will make 100,000,000 iPhone 5 phones in 1 year. Rockwell will make 1,000 787 avionics cabinets in 10 years. The testing on the avionics equipment is pretty intense but there are times where items will fly with various dispositions. I have seen many devices that fail EMI but will fly and cert with a disposition. I know of a C-17 sub-system designed in the '70's is still flying with the original disposition. We deal with lots of safety numbers looking at things in the 1x10^-9 and 1X10^-12. We are looking at somewhere around 1x10^6 to 2x10^6 commercial flights/year. I turn "off" (sleep in airplane mode) my devices for a reason. ---------- Quote:
Don't forget about that "has determined" clause. That requires TESTING. This is why the iPad is allowed on the flight deck for some uses. |

The reason the FAA did the iPads is because they conducted testing that found it was safe and served to help the pilots in keeping up-to-date charts and what not.

I have heard the interference in the headset as well as over the frequency from other planes when they are transmitting, it carries through. I even heard it once from a tower controller. It does happen, maybe not in your particular case with mysterious hydraulic avionics. But in other, non fantasy equipped airplanes, the interference can be heard. Would it help you to shut it off if I told you that running a cell phone at altitude is just about the quickest way to run down the battery. B ---------- Quote:

Restricting use during take-off and landing is really more about keeping everything in order so if there is a problem (unexpected turbulence, engine failure, landing gear failure, evasive maneuvers, etc... all far more likely during take-off and landing), then you don't have so much crap flying around the cabin hitting people in the head and bags blocking folks from making a safe emergency exit (and if you've ever been on a commercial airliner during an emergency landing, then this is going to make sense).
The whole "interference with aircraft systems" rant has become a ruse that keeps them from having to switch their story to one of "safety in the event of an emergency". Regardless, it is a little silly that I can't read my Kindle, but it is perfectly ok to read a hardcover textbook

Bravo. Especially ridiculous when they insist on turning off devices with no network capabilities at all, like basic iPods. Nobody is stupid enough to believe that those would pose any risk at all.

To recap, I've flown a 35 year old plane and a 4 year old plane. My evidence still stands. Quote:
Testing is done. It's already being deployed. With that, there is no reason to have that regulation in effect on Part 121 operations. BTW.. If this (radio interference) were a problem, UAL's Ch. 9 service in their IFE would have been shot down decades ago. It hasn't, is still being used, and is also being deployed on the fleet they inherited from COA. Quote:

As for my checkride, I'm sure to pass it. It is when some people who are telling us who do fly that what we are personally seeing and experiencing is wrong without being up in the plane with us is what ticks people off.

I did misspeak about 'hydraulic', though that still does play a part in the older models. analog and gyroscopic are the better/proper terms. BL. |

common sense & safety
here's how i see it & yes i'm probably repeating much of what's already been said: the faa's rules are there to address a combination of common sense + safety issues:
1) it's not unreasonable to expect passengers to pay attention during take-off & landing (no matter how many flights you've been on) - you may not feel you are a risk to yourself, but, you could be a risk to someone else 2) laptops, ipads, etc.. are potential projectiles & especially in the case of laptops obstacles that could impede the evacuation process in the event of an emergency & yes, fwiw no-one really still believes that interference is a real safety risk - all modern avionics are shielded & tested to ensure that imho - removing those rules is more of a risk to the flying public |

Bottom line is it's not the interference, unexpected things can happen during take off and landing, which is why even the flight attendants are seated with seat-belts during take off and landing.
The issue with having ANYTHING that's not paper not under the seat in front of you or in the overhead bins is that it can easily become a life threatening object if something does happen. It doesn't matter if it's electronic or not, which is why purses, etc. have to be put under the seat in front of you when taking off. Now, I wish the FAA would simply come out and say that this is why they are not being allowed, not because they are electronics. The electronics shouldn't necessarily have to be turned off, but they should have to be safely put away. I do hope that they never allow cell phone use on the plane, can you imagine 200+ people all trying to talk on the cell phones? Even if only half them did? |

Cell phone towers are like TV station antennas. The signals are spread out in every direction, tent-shaped from the tower. So the higher the tower, the further down and out the signal can be received. That's why you notice that most TV station antennas are in the parts of town that have the highest elevation. Cell phone towers are nearly the same, but not as tall, and in more locations. The signal still goes down and out. So being above the tower, especially anywhere between FL180 and FL600 won't get you much signal. Additionally, VORs operate in the reverse. From where they are based, the signal is received the further up and out, as opposed to down and out. Without getting into flight plans, routings, airways, and the blood/guts of how flights are routed, the only signal a phone could pick up are on frequencies lower than what it operates on. Compass... that would be another story. BL. |

2. They are freaking glass-loaded projectiles during an incident, and most incidents happen during takeoff and landing. Either one of these would be enough to scare me, but I'm a PhD in disaster recovery, so I'm paid to be paranoid. |

Flying... Not what it used to be.
Aside from the huge differences in how we're treated on aircraft today, which is a whole separate list of complaints... The electronics issue is indeed absurd.
I'm an aviation fan. So, when's the best time to take photos? Takeoff and landing, the two times when you're not allowed to use a camera. I've even been told to put away my FILM camera on planes in the last few years, because it contained a battery-operated light meter, and therefore, is an "electronic device". There's a MUCH more dangerous issue with electronics than just using them normally. Watch any modern survivalist show, and see what happens when you puncture a lithium ion battery. Reading an article on your iPad? Not dangerous, in any way I'm aware of. (although it wouldn't surprise me if, at some point, manufacturers made it possible for airlines to automatically place your device in "airplane mode". |

Not sure what the laws are in the US, but the law surrounding this matter in the UK haven't really been updated much in the past 25 years or so. This is way before the digital phone network existed and everything was on the Analogue 1G system lol.
Wouldn't that legally mean the law doesn't actually apply to our modern tablets and mobile phones, since they don't operate on the 1G system?

We know Senator are experts
Unless I see proof beyond reasonable doubt, one should assume all politicians don't know their ass from a hole in the ground.
Therefore, by assumption, US Sen. McCaskill doesn't know what she is talking about, and further, just because the flying public is growing "increasingly skeptical" (they are also growing increasingly clueless), does not mean we should codify stupidity into the law. South Carolina recently passed a law denying global warming (not just human caused). At no point, it seems, can knowledge and truth trump uninformed opinion. Now, the only basis for allowing the use of electronic equipment to be used by passengers is physics. The only question that is relevant is "What electronic equipment which passengers bring aboard that will generate EMR that will interfere with the electronic equipment used by the aircraft?" This is a question solely for electronic engineers and scientists to answer. No one else must have a say in this question. I don't really care what McCaskill or the flying public wants. Don't publicized the increasingly stupid opinions of the politicians and the public by passing laws forbidding the laws of nature. |

Devil's Advocate:
My roommate who has been flying or has been flown around (his dad always had a pilot's license when he was alive) says he has seen electronic devices cause weird interference before. The difference between them allowing pilots to use iPads and passengers is the pilot can see if it is causing interference and turn it off. If a passenger's is on without the pilot knowing, or all he knows is several are on, and interference happens, he's not going to know which caused it. And taking off and landing is the time most likely when an accident is going to happen. The FAA does have regulations to show what can be used but they are very specific to each device. THe reason the airlines don't allow them on take off and landing is they'd have to have every single device tested to make sure it didn't cause interference. With how many different models of tablets and phones, that's just not feasible. How about the senator leave the ruling up to the FAA who has more people who actually know about flying rather than a senator who doesn't know all the complications and needs of pilots and ground control. (Edit: or exactly what the person above me said. This kind of thing should be left for scientists and those in the know, not some senator or public demand who don't know as much). (and trust me, if they come out and say, "Hey, yeah, it is safe." I'll be very happy as I want to be able to use my devices on take off and landing. I'll even admit I'm a hypocrite and I still play my ipod/music device but I don't try to wi-fi or do that kind of stuff). ---------- Quote:
Take off and landing is where most accidents happen, and at busy airports ground control may not have time to give another warning to the pilot if he doesn't hear the first one. ---------- Quote:
I would love to see this much concern and outrage over the crap TSA is allowed every time we are scanned. And it's all public safety theater, it really doesn't do much (everything they do is reactive, not pro active). And yet, as this person says, people are more outraged over not being able to use their electronic devices for 20 minutes during take off and landing. There are a lot more serious things the public should be outraged by but stays silent on .---------- You know flying is so safe because it is very highly regulated to take out a lot of variables that can cause issues... not because we have super technology that doesn't fail.

It's about freedom from unnecessary regulations. Why do you care why people want their devices on? Go ahead and be high and mighty about how you don't "need" your device on, let me listen to music on my iPhone during takeoff.

"The problem with aviation is that for 50 years it's been populated by people who think it's this wondrous sexual experience; that it's like James Bond and wonderful and we'll all be flying first class when really it's just a ... bus with wings,” O’Leary told The Telegraph. "If you say to passengers it's £25 for the seat and £1 for the standing cabin, I guarantee we will sell the standing cabin first.” I marvel at the insane security theater we go through every time we travel from one place to another, and remind myself, it really is just a bus with wings. We would never submit to such silliness before getting into our cars every day, and the ironic thing is that is way more dangerous than flying! I also tell myself, as I look at the TSA screener "This person will come to work day in, day out, for YEARS and NEVER find anything more dangerous than a bottle of water or deoderant." We need to put things in perspective!! |
