Finland Announces an Anti-Laser Campaign For Air Traffic

Posted by samzenpus on Sunday December 21, 2014 @08:03AM from the stop-pointing dept.

jones_supa writes Trafi, the Finnish Pilots' Association, and STUK, the Finnish Radiation and Nuclear Safety Authority, have launched a joint campaign against air traffic interference with the title "Lasers Are Not Toys." Ilkka Kaakinen from Trafi says that laser pointers interfering with air traffic is a real problem in Finland. "We receive reports of several cases of laser interference every month and every one of them is potentially dangerous," Kaakinen says. Last year, 60 cases of laser pointer interference were reported in Finland, and the figure for this year was at 58 in November. Despite the continuing interference, only one person has been caught misusing a laser pointer in this way in Finland. That single person was not convicted of a crime, as the court was not able to establish intent. Kaakinen says other countries hand down severe punishments for interfering with air traffic, even years-long stretches in prison. He also reminds that it is important for users of laser pointers to understand that the devices are not toys, and that children should be warned of the potential danger in using them irresponsibly – or ideally, not given one at all.

  Sadly, most of the arrests have been people in the age of majority - perhaps they had the maturity of children, but they aren't children. Plus, given how expensive they are (several hundred bucks), it generally isn't a children's toy.
  As for those claiming that it's not a problem because no one's lost a life yet - really? Aviation already is built upon the blood of many people, some of whom lost their lives over something as stupid as a light bulb.
  And no, it may not be a direct cause, but it may be the last link of a chain of events that leads to an accident. Every mishap has been a chain - if any one of those things were different, it wouldn't have happened. Perhaps the pilot is in bad weather already trying hard to find the runway and then a flash comes across the cockpit. He blinks, it goes away, and he continues, but what he thinks is the runway is a after glow spot (similar to how a flashbulb causes temporary spots) and boom, crashes the airplane into a building along the glidepath.
  And perhaps someone you know is on that plane.

It's the temporary blinding effect that is so dangerous, where pilots are unable to read their instruments for a critical period during takeoff or landing.

A laser that makes me not see and avoid the power lines ahead will kill me just as effectively as if it had been a photon torpedo fired from the USS Enterprise.
  
  When an airliner is landing, this is also a critical phase of flight. Blinding the pilot then will make it impossible to read instruments, possibly if not probably resulting in the aircraft departing from the glide slope and runway centerline and into a collision with airport surroundings.
  
  You're right that no aircraft in the US has been shot down yet by a laser, although some pilots have suffered permanent eye damage. This is where the part about you being dumb comes in.

  Not just no aircraft in the US, no aircraft in the world has had anything more than a pissed off pilot at landing.
  You seem to be arguing like I'm saying people should target aircraft at landing with lasers, its no big deal. Re-read what I said... I mentioned at least twice that you shouldn't do this. Stupid kids do this sort of thing. But this is heading in a very predictable direction. They are trying to ban consumer lasers with this lame excuse. Is there a possibility that the right laser, hits the right pilot, and distracts him enough that it really does cause some sort of problem? Yes it's remotely possible... but the chances are so remote that I feel safe in saying it will never happen.
  But like I said, if you want to be ultra-super safe... install polarized plastic lenses over the windscreens. Remember we used to stick them on laptop screens? They cost about $5 each. But they haven't done that yet... why? Because the risk is so remote it's not even worth spending $5 to protect against. Do you think the owners of multi-million dollar jet liners would risk their aircraft when the fix was so simple if it were really a threat?

  Who cares if the chance of hitting the planes if incredibly small... using this argument it should be legal to stand in your garden with a blindfold, and shoot at your house with a BB gun. The chance of hitting a window would be small, the chance of hitting you even smaller, so if one did hit you it would be an "accident".
  About the "jitter from your hand" argument... what if one has the laser pointer mounted on something that is easy to aim... like a riffle. Rifles are designed to be held steady, even a toy would do.
  Considering that only a complete moron would point a laser at plane, shouldn't this be something that one bans "just because its a good idea". Exactly why would one be stupid enough argue the case that "because no-one had died yet, it probably isn't a problem".
  ps. could you give us the licence plate number of your car, so that we know to point lasers at you if you drive by.

  What?! 5000 feet?! This story is utter BS. Let's take, for example, specifications for Wicked Lasers Krypton ("The Krypton is the world's most powerful green handheld laser", priced $999). "Beam Distance 0.25 Lux - 47475 meters". Let's assume that the beam was from the ground at about 45 degrees. This gives the distance of about 7000 feet. (47475 / (0.3048 * 7000)) * (47475 / (0.3048 * 7000)) * 0.25 - this gives about 120 lux. To put this into perspective, direct sunlight is more than 32000 lux. Yes, laser is a point source and Sun is not exactly but that should not matter with such a difference.

  All you've done is provide evidence of some pilot's eye getting damaged.
  You have failed to provide any evidence about how you need eyes to fly a plane OR any evidence about crashes due to pilots being unable to see.

  > lighting up a windshield with 100+ lux will kill visibility at least which is the main complaint from pilots trying to land
  No, the main complaint in the discussed article was eye injury (that cannot happen), not losing visibility for a minute.
  
  > A couple watts at a spot size of ~ 1-2 m can reach the damage threshold in the visible range
  No, they cannot. The limit for a fully dilated pupil is 9 mm which means 2000 mW / (1000 / 9) / (1000 / 9) = 0.162 mW of laser power enter the eye for a very short moment. Class II is 1 mW so even taking into account beam imperfections such a blast is significantly weaker. Learn basic math please.

  > Learn to read... as this clearly stated that that sentence was referring to a common complaint by pilots, not the particular article.
  Do it yourself - the comment I answered to was only about eye damage and the title of the referenced article is "Pilot Has Eye Injury From Green Laser".
  
  > MPE is for visible region is 1 mW / cm^2, which can be reached with single digit watts into a meter diameter beam, assuming the beam is evenly distributed and has no potentially reflecting surfaces involved.
  Wow, now it is "single digit" watts, there is certainly a progress over "a couple of watts". But no, it cannot be reached, it would be 0.7 mW / cm^2 from a 9W laser in the specified conditions. Just learn basic math as I told you :D.

But I recently got a Barrett M82A1 and love to see just how far I can shoot the .50 cal rounds to hit things.
Does this version sound any better?

I would have thought that your analogy would have required an extra special level of dimwit except:

and then there is this nincompoopery:

But my thing is that I like to shoot a laser across say a body of water at the storage building miles away which presuming some common sense results in zero harm. But few would debate the harm in shooting up at an airplane. The key being that a few would debate the harm; a few dimwits. But assuming no harm few would debate that hitting things with a laser is fun as many would think that hitting things with a 50 cal would be fun too. Just clearly more dangerous.

  Naval Lt. Cmdr. Jack Daly and Canadian helicopter pilot Capt. Pat Barnes suffered eye injuries hours after an aerial surveillance mission to photograph a Russian merchant ship that had been shadowing the ballistic-missile submarine USS Ohio in Washington state’s Strait of Juan de Fuca. The Navy recently turned down an appeal from the Defense Department inspector general to award Cmdr. Daly a Purple Heart for the incident. Cmdr. Daly, who retired from the service last year, continues to suffer eye pain and deteriorating vision.

  Why does there need to be a "problem", there is no "good reason" to point lasers at planes.
  If you have a car, please post your licence plate number so that we can make an objective study of whether you will crash if people point lasers at your car.

Considering an unsteady hand, perhaps you shouldn't be thinking about it in terms of a quadratic relationship but rather in terms of a linear one? Hint: draw the geometry of the light spot passing over the eye in both cases.
