I heard on the radio that a small plane from Chicago went missing in the fog
during a landing attempt at the Toronto City Centre Airport. This morning I see in the newspaper that the plane and the pilot have been located at the bottom of Lake Ontario. The plane was a Beechcraft that could seat six people. There has been no known reason, as yet, as to the cause of the crash, according to the article. I think this type of crash may be preventable, if it was due to poor visibility, by the construction of radio signal buoys parallel to the runways lights and a simple receiver on board light aircraft. Or visible laser beams criss crossing over the runway. All of this technology is available, is it not? |

We have radio signals that parallel the runways, they are called localizers.
Light beams have been tried all the way back to before WWII without any favorable outcomes. Rick Pellicciotti "Wooduuuward" wrote in message ...

It is becoming more and more apparent to me (and others, I would think) that you are new to aviation. As a place to learn, this is a great forum. I do have a suggestion that will keep you from coming off as a know-it-all, or an ass. As in the case of this post, instead of suggesting a solution to a problem, why not come out with a question, as to what is available? You will get answers, but without making yourself look foolish. In other words, be humble, confess that you don't know it all, and seek answers. It will keep your reputation much less unstained. YMMV. -- Jim in NC |

If you can't see that, you can't see a laser beam either. -- ----Because I can---- http://www.ernest.isa-geek.org/ ------------------------ |

Many runways have localizers or other radio aids to help aircraft land. The
most precise of these is the ILS system, which allows you to not only track in to the runway, but also guides you down in altitude as well. GPS with WAAS promises such precision approaches will someday be available at airports that do not have expensive ILS equipment. There is no such thing as a visible laser beam. In order for you to see any kind of light, it has to be reflected off some kind of surface. If you want to see a laser beam you have to shine it through a fog or cloud of dust of some kind. I know that in Hollywood you can always see laser beams, but all Hollywood movies use physics from some other universe than our own. This is why in movies you not only see laser beams, but also bullets always flash when they hit something, people can outrun shock waves, and people can stand around in shorts and without oxygen masks in a cargo plane that has the doors open in flight, but the hero needs oxygen and a protective suit the moment he leaves the airplane. You cannot shine a laser beam at an airplane cockpit because it might blind the pilot. The same fog or clouds that render an airport invisible will also obscure a laser beam. |

The area was fogged in at the time of the crash.
