Laser Warnings Planned for Out-of-Bounds Pilots

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.

    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.

      1. An airplane is not required to have a radio, unless flying in airspace where it is required. Some planes don't even have an electrical system to support a radio.
      2. Some pilots in an airplane without a radio carry a handheld radio (powered by batteries), but only turn it on when it is needed (i.e. takeoff and landing).
      3. An aircraft comm radio has 760 "channels" (different frequencies). 121.5 MHz is the univeral "guard" or "emergency" frequency. But, pilots typically don't listen to it unless there's a need to do so.

      You're SUPPOSED to be listening on 121.5, though that doesn't have the force of law (yet).

      The FAA stongly encourages all pilots to listen to 121.5 at all times unless there is a reason not to be, as in your description of aircraft without electrical systems. They would even like you to be listening to 121.5 even when communicating with ATC on another frequency. Most aviation audio panels support this if there are two recievers.

      Keep in mind, the restricted area around D.C. lies well within the 30nm mode C "veil" around the major airports. What that means is, in order to be even NEAR the restricted area around D.C., you've got to have an altitude encoding transponder, and it has to be on. So any aircraft likely to accidentally penetrate the restricted area will have an electrical system. I doubt there's too many airplanes out there with transponders and no radios.

      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.

    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 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 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, 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.

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.

    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."
