![]() "m pautz" wrote in message news:XACzc.37718$eu.24221@attbi_s02... In the old days, tower requirements were white and orange paint to bring attention to the tower during the daytime and Blinking Red lights to bring attention to the tower during the night time. (remember the white and orange towers???) Sometime in the 70's the rules were changed such that the towers did not need the white/orange paint if they had 24 hour stobe lights. Didn't that have something to do with visibility during fog (the strobes)? |

All I remember was the advent of the strobe in replacing the red flashing beacons. The strobes were so bright that they could be visable during daylight hours and the need for the white/orange requirement went away. I presume that the change was strictly due the advancement of technology and the developement of high power strobes. I am almost hesitant at posting this since it is a presumption.

... Increasingly, I am seeing strobes within red traffic lights, and even within red octagonal stop signs. They do increase awareness, but of course in the end will lead to accidents at the traffic lights / stop signs that are not so equipped. Just like when they added the third brake light to motor vehicles, there was an increase in rear-end accidents with vehicles that didn't have the third brake light. Yeah, right. Your "of course" leaves something to be desired. Pete |

You're testing my memory; I can't remember the reasons. I used to be a broadcast engineer at the time. All I remember was the advent of the strobe in replacing the red flashing beacons. Likewise...but I vaguely recall (my memory is going almost a fast as my knees) at least one factor was that the strobes were much more visible during fog. I'm dead sure that the fog issue was not the ONLY one. Or, was it just a dream? :~) The strobes were so bright that they could be visable during daylight hours and the need for the white/orange requirement went away. I presume that the change was strictly due the advancement of technology and the developement of high power strobes. I am almost hesitant at posting this since it is a presumption. Most likely you're right...that the technology was there and they, wisely, took advantage of it. |

That strobe could help correct a nasty case of lack of situational awareness. Of course, that lack might also be corrected by an unlighted tower, but the cure might prove fatal to the patient.

George Patterson None of us is as dumb as all of us. The height is actually dependant on terrain. Typical values may be in a flat land area, but where I live they are closer to 100 - 150 feet high. I don't think this can be applied bas a rule of thumb beyond a local area. z |

George Patterson None of us is as dumb as all of us. My only reason for asking is this, if we are not supposed to fly lower the 500ft AGL, why would this be a concern? The only location I could see that this would matter is in the approach path. -- Mike Flyin'8 |

500ft AGL, why would this be a concern? That's not true! Only in certain areas. |
