      On a radio with 5kHz steps, being 4kHz off means you're closer to next frequency up or down than you are to the one you are trying to work, and you probably ought to deliberately detune your radio to be closer to on-frequency.

Full power is maintained until around 1500 feet, while the aircraft speed continues to increase to around 250 knots. Sometime before around 200-210 the flaps are retracted and angle of ascent is dictated by the 250 knot regulation.... you hold at 250 knots until attaining 10,000 feet. Then level at 10,000 feet and build up to about 300 knots or so before beginning the final climb to cruising altitude (and speed). There's some adjustments that happen around 25000-27000 as atmosphere thins and airspeed drops, which is normal and usually some pitch adjustment occurs to continue the climb safely until achieving cruise altitude around 35-40,000. That's usually when the pilot kicks on the autopilot, levels the wings, and comes on comms to announce to the world he's bored for awhile. :)

      From rotation (V2) to 10,000 feet, it is about ten minutes... obviously this can vary depending on the airport, local conditions, weight, just to name a few things... but 10 minutes is a good average. It just seems like longer because you're stuck on the ground waiting for takeoff, then clearance, then actually powering up and starting down the runway, etc. In actuality, from the time you start taxing until 10,000 feet, it's probably more like half an hour on average.

However, this is all happening on the audio-frequency side, so calling it "interference in the aircraft frequency bands" is just plain wrong -- it will affect practically any unshielded or insufficiently-shielded device (it's only a couple watts or so transmitter, but within a meter or less the inverse-square law says you do need better shielding than a lot of consumer electronics have) with an amplified audio output, including all sorts of radios, and non-radio devices from MP3 players to cassette players.

      I don't think people on their phones mid-flight are likely to be a significant problem in the near future at least. For one thing, you're rather unlikely to get signal at a high altitude unless the airline installs repeaters on the plane (if you fly a lot you might notice every so often on flights that about 5 minutes before landing people suddenly start to receive a lot of texts; that's because they left their phones on by accident but didn't have signal until the plane got lower). And of course you can guarantee if the airlines do that it will be expensive to use, at least for the first few years, and therefore not used very much for calls - how often did you ever see people using AirFones when they were still installed in nearly every seat after all? (though people's phones would still ring with a repeater which could get annoying I suppose).

      For another, aeroplanes are actually very noisy environments - it's amazing how quickly the human brain can simply tune that background noise out (which works since it's pretty constant and unchanging noise) - but unless you have something like a jawbone headset, the person on the other end of the call might have a bit of a hard time hearing you so most calls are likely to be pretty short.

All that playing with the phone in the airport and on the way to the airport really drains it. You can't play with the phone the whole time if you want to save some battery for after you land. Smartphones go down fast just through light use, like reading the news and facebook. The new game, Plants vs. Zombies 2, is so battery intensive, it uses battery faster then it can charge. It overheats the phone, and the phone refuses to charge properly. So even if you keep the phone plugged in, you are going to run the battery down to zero. This happens if you turn on hotspot mode too. Try to use the phone as a mobile hotspot and charge it at the same time, it overheats, and eventually dies, while still plugged in.

    Which by itself is a major change in policy, and when combined with bt, wifi, and all the other changes, is yet another counter to "no change".

    This was never a big issue for me, really, ... I still don't see this as some grand revolutionary rule change, more of a minor increment.

    You don't care, so it doesn't change anything. Ok.

    Once they allow actual cell connections (even if only for texting and not voice calls) and LTE/EVDO data connections, I'll throw my hands in the air and cheer with everyone else.

    Not everyone will be cheering that change.

    And then hope that the technical hurdles can be overcome...

    That change will not happen until the technical hurdles are overcome.

    yep. real work. done by the Cisco guy who shows up at your company site to install the equipment you just bought and get you dr site up. the EMC consultant who shows up at the hospital after it's basement datacenter flooded to replace the damaged storage array where all your xray images are stored for your surgery tomorrow. the IBM guy who's with him to get the new server up to replace the one under water, so they can see the new storage array. The guy from Oracle who shows up at your bank when some idiot puts a hint statement in his sql that brings down the performance of the database to a crawl during that time you're generating your company's paychecks. I guess compared to cleaning shit off of burnt dead bodies would definitely be more 'real' in comparison - I guess that's what you do?

    It won't work even if you try to use cellular service. I always get "No Service" when I use my phone on the plane.

  38. Being required does not make it a good idea by sjbe · · Score: 1

    It's not the airlines, it is the FAA. Preflight briefings are mandatory

    That is not the same thing as proving that a briefing on how to use a seat belt a useful activity with demonstrable safety benefits. They also used to be required to ask if I had packed my own bags on the apparent (absurd) assumption that any terrorist would break down and fess up. I defy you to find a shred of evidence that pre-flight seat belt briefings have demonstrably saved a single life in the real world. You know, someone saying "whew, if it wasn't for that pre-flight briefing on the seat belt I'd have burned to a crisp". It's the sort of thing that sounds good to an FAA bureaucrat but in reality there is not a bit of evidence that it actually serves a useful purpose.

  39. Satire by sjbe · · Score: 1

    Ah, the standard Slashdot "you are right". Abuse and a complete change of argument.

    Abuse? I think you need to thicken your skin up a bit. Furthermore look up the word satire. I think you'll find it helpful here.

    You implied that car belts make one an expert at aviation belts. I pointed out they work in unrelated manners.

    I didn't imply it. I stated it outright. And I also pointed out that the fact that the number of people for whom the different release mechanism presents a problem is a pretty good approximation of zero. Go ahead and prove me wrong. Find a shred of evidence that the in flight briefing has demonstrably saved a single life and I'll retract my satire. But without evidence you are just hypothesizing about theoretical and unlikely failure modes.
