Laser Warnings Planned for Out-of-Bounds Pilots 258

akadruid writes "No, it's not a new 'Star Wars' system: The US Pentagon and NORAD are using lasers to warn off pilots flying into restricted airspace, according to Wired magazine. I wonder if they got the idea from the FBI, who charged a New Jersey man under anti-terror laws for doing this?" The system is not yet in operation (but could be as soon as next month), and according to NORAD, their system has been found safe for pilots' eyes.

    ...RTFA.

    Yes, it's ironic and ha-ha funny and all considering the instances of lasers being shined into cockpits as pranks.

    But:

    The North American Aerospace Defense Command, or NORAD, said its laser warning system will start in 30 to 45 days. The low-intensity lights are less powerful than the ones that prompted warnings, and tests have shown they are safe for the eyes, according to NORAD.

    NORAD spokesman Michael Kucharek said the laser-based warning system someday could replace fighter jets as a way to warn pilots to stay away from the Capitol and the White House.

    Hundreds of small private planes     [i.e., not commercial jetliners] have strayed into the restricted airspace in Washington, a 15.75-mile radius around the Washington Monument.

    In some cases, NORAD has had to divert or scramble fighter jets to escort them away from the area at a cost of $30,000 to $50,000 each time, Kucharek said.

    The challenge for NORAD will be to educate pilots that the red-red-green flashing laser beams mean they're flying in restricted airspace.

    Isn't looking for a new or novel notification system for myriad planes that may not be able to immediately contacted via radio or identified by radar or other means a good thing? And one that mitigates the need to divert or scramble fighters at great costs?

    And yes, I suppose someone could build a system to emulate the NORAD system as a joke/hoax/prank/whatever, as no doubt dozens of drooling slashdotters are anxious to post to echo Timothy, but then, it would be:

    - First of all, very unlikely to be encountered, statistically, and when it did happen, it would be:

    - Not anywhere near restricted airspace, meaning it would be recognized as a prank to be ignored
    - In the case of much of DC around the capitol, in restricted airspace anyway, and therefore moot
    - Likely that instances that would cause significant confusion and/or be mistaken for a legitimate NORAD warning would be about as prevalent as current laser pranks. That is to say, not prevalent at all, compared with the total number of flights.

    So in sum, this is a very good idea and not at all surprising.

    Further the fact that a man has been (rightfully) charged with a crime for shining a fucking laser at a plane like a dumbass has absolutely nothing to do with a safe, non-obtrusive, well-designed warning system that coincidentally also uses lasers because of their utility that is only invoked if a pilot strays into restricted airspace in the first place, which are likely to be small, private planes, as indicated in the article, and NOT commercial carriers with experienced pilots who know, and have the tools, to stay out of restricted airspace.

      It just says that the light wouldn't be as intense as in the cases where people have gotten in trouble with their laser pointers.

      That seems a little hard to believe at first, since a green laser pointer's power is only something in the milliwatts, and the AOPA article [aopa.org] mentioned in another reply (this is a fixed URL, incidentally) talks about a 1.5 watt laser. But that's reflected/diffused to create a 100-foot-wide line of light in a circle 10 miles from the laser, so I guess by sending the light off in all directions (not at all like your normal use of a laser) it's possible that it wouldn't be a problem.

      Out here in Hawaii, the summit of Mauna Kea is an "informal" no-fly zone. There aren't any major flight paths that would cross it anyway, and since there are telescopes on it, folks have basically just agreed not to go flying over when we're trying to see things.

      This has become a little more important in recent years, since the folks over at Keck [hawaii.edu] use a laser to ionize stuff in the sodium layer of the atmosphere and create an artificial "guide star" that they can then measure the light from to correct for atmospheric interference. This is part of their adaptive optics, I think. That's a 15-watt laser, which could really ruin a pilot's day.

      And Gemini North [gemini.edu], across the summit from Keck, is about to start playing with a big bright toy too.

      They've got a pool of "plane spotters" who spend half a night standing outside on the summit with a walkie-talkie. If they see any planes that look like they might get in the way, they radio in to turn off the laser before anything gets zapped.

      I'm going to try to do that, one of these days. Goodness knows I'm up there enough as it is.

        Seems to me this is just a public relations stunt. NORAD was initially formed during the cold war as a quick response system to scramble fighter jets in case a russian bogey entered our airspace. They never had the opportunity to truly flex those abilities up until 9/11, during which they had fighter jets up in the air pretty quick, too bad they flew out over the ocean and flew in circles. So now I guess they've found something they're good at, shining LAZERS (!) at small aircraft.

        Seems to me they could shut NORAD down, let the national guard do its job, and the FAA should monitor restricted airspace.

      Too complicated. If the pilot knew enough to memorize the light patterns, he'd know to avoid the ADIZ area without going through the 3-hour process of getting permission. As it is, the program is destined to be a useless waste of money because red-red-green means no more the average pilot than it does to anyone else. It's not one of the standard light signals that towers use.

      The program's only potential saving grace is the slim possibility that a pilot would (a) notice the lasers, and (b) realize that they're directed at him as part of some offical government operation (a slim chance at best). He may then tune to 121.5 assuming he's in trouble and get instructions there.

      In reality, the program is just another amazing waste of money designed to set the congresspersons at ease about their safety.

      It may also be part of the government's legal defense after they shoot down their first civilian. "Well, we shined our lasers at him and he didn't respond, so we fired a SAM across his spinner as a warning shot..."

          A GPS receiver that's FAA-certified for installation in an aircraft is a multi-thousand-dollar piece of technology, and there are literally thousands of aircraft out there that have no GPS on-board whatsoever. All these would have to be retrofitted, and a large number of experimental and homebuilt craft would have to be totally redesigned in order for a GPS system to be installed. Remember, not all aircraft even have electrical systems!

          A handheld is fine (and much cheaper), but the FAA says they're not legal for navigation. They're simply an "aid to situational awareness." Furthermore, handhelds don't have a good way to alert the pilot if he/she is about to violate some kind of airspace, as they don't have a connection to the aircraft's audio system, and -- once again -- not all aircraft even HAVE audio systems.

        The "problem" is more a figment of our legislators' collective fears and feelings of self-importance than anything else.

        After 9-11, congress felt that their own office space was definitely important enough to be a terrorist target (strange, I though the terrorists passed up DC and hit the Pentagon instead...), and since our country could not survive without the current set of elected officials, they MUST protect themselves for humanity's sake.

        So they decided that any aircraft within a 25000-square-mile area around DC (which includes no small number of airports) must file a special type of flight plan, remain in contact with ATC at all times, and must follow a whole laundry list of restrictions. It's called an ADIZ, and it's a royal PITA, can delay your flight for hours, and has ATC overtaxed to such a degree that flight safety has been seriously compromised on a surprisingly huge number of documented cases. This includes more than a few near-collisions at airports that were avoided only because the pilots were paying closer attention than ATC, while the controllers were busy with these extra restrictions. The situation is a string of disasters waiting to happen. Without the pilots' extra vigilance, the death toll for Congress's arrogance would already be in the hundreds.

        In the mean time, there have been a large number of airspace infringements. These are generally caused by things like equipment malfunctions (eg. radio or transponder that goes bad in flight), unintentional flight path deviations (like being blown off course), and sometimes lack of knowledge about how damn huge this protected airspace really is. It's really a unique and unprecidented situation, and some older pilots don't know what to make of it. And on at least one high-profile occasion, the problem was the incompetence of the defense department.

        In the near unanimous opinion of us non-congresspeople, the problem is the airspace itself. We're no safer--and in fact, many people's lives are often at risk because of it, including (and especially) all normal air passengers in and around DC. But rather than dismantling the airspace, they're working to strengthen it. This includes the recent addition of missile installations (whose sole purpose is to shoot down Americans), and now this laser warning system--none of which exists even around actual prohibited airspace.

        What congress needs to learn--and what they'll never admit--is that congressional elected officials are (a) not a serious terrorist target, and (b) completely and absolutely expendable. We may even be better off if we were to wipe them out and start over.

        Ironic subnote: I frequently fly my plane directly over NORAD without violating any airspace at all. In fact, I could fly it right down the tunnel and the only regulation I'd be breaking is the one about "500 feet from any structure, vessel, etc."

    Could they not just use the targeted lights (I don't think they are lasers) that are used, at least in Canada (and probably US) for air traffic control in the event of a comm radio failure? Having looked right at one (from a plane, practicing approaches with comm failure), I can guarantee that it won't make a difference. The problem with any system is, if the pilot is not expecting to see something, it has to be rather large. There is a lot of area to monitor for traffic and whatnot, and even as I'm about to embark upon my first solo flight, I'm still not great at picking up traffic the first time I look.

    There is restricted airspace everywhere, and usually a violation thereof means a serious consequence. My flight school had to modify all its flightplans into Medicine Hat, Alberta (I live in Calgary) because some genius forgot to check his chart for the military restricted zone. My point in this long rambling post is that, if you know there is restricted airspace nearby, try really really hard to stay the fuck away from it. If you don't know you're flying near restricted airspace, then you fucked up during the planning stage.

    • If you don't know you're flying near restricted airspace, then you fucked up during the planning stage.

      How can you know if you are flying in restricted airspace, when the Homeland Security has had the airspace restricted secretly... ie, it's a restricted area, but they won't tell you where it is for fear that terrorists might attack it...

    • I'll just say a big "YES" to that last paragraph, and further advise pilots who might be reading this to, as AOPA says, "talk and squawk" as much as possible. Pick up VFR Flight Following if possible. And for the love of all things holy, take a free online airspace awareness course [aopa.org] from the Air Safety Foundation.

      Fly safe.

      Further to the above info, there are a number of different types of airspace that you should stay away from.

      In Australia, outside of the normal classes A-G of airspace we have Prohibited, Restricted and Danger areas.

      Basically, Prohibited means stay away, we don't care who you are, go away! I think the last Prohibited area was around Woomera, but was downgraded to a Restricted area.

      Restricted areas can be active 24 hours, or activated at various times. Most military flying bases will have associated res

      • Ah yes... in Canada we have class F airspace, which can either be advisory (like parachuting, training, aerobatics, etc...) or restricted (low airspace above prisons, military areas). We also have an ADIZ around the entire top of the country, in case those Russians attack us!
  • I'd think a voice on the radio saying "turn around or we'll shoot you" would be fine.

    Tracers from a nearby F-16 are probably equally as effective.
  • Um, wouldn't it be easier to fit pilots with electric-shock dog-collars and setup a few thousand miles of invisible fence?

  • Just a few gotchas:

    • The average amount of cloud cover for the month of March is around 43%
    • The chances of a pilot getting lsot and straying is much higher when they can't see landmarks.
    • If it's cloudy the pilot better be "IFR", on instruments. This usually means he has the seat cranked down and eyes flitting between the altimeter, rate of climb, gyro compass, and the attitude indicators-- i.e. eyes in the cockpit.
      • So the whole laser concept works only in clear weather, when it's needed the least, and do
  • The diffused laser beams mentioned in the article would be as safe as a high powered lamp, such as those used by the tower to guide planes in for a landing when their radios have failed.

    Since lasers are VERY monochromatic, and operate on a few specific wavelengths it would be possible to develop protective eyeware that would block the laser beams, but still allow normal vision. These would protect pilots from "terrorist" laser attacks.

    I'm waiting for laser pointer pens to be outlawed because of the 'thre
