Easy Unit Converter Once we got above 14,000 feet the wind speeds didn't seem to change with altitude. "This applies much more to light aircraft than airliners, but it is illegal to fly below 1,000 feet when over a built-up area, or 500 feet over any person, vehicle or structure," said Richard Taylor of the CAA. But given that this is The Twilight Zone, Justin ended up becoming the impetus for such a disaster, and everything else leading up to The following information has been adapted from the modern version of the Beaufort Scale, which ranks wind speed from 0 (calm) to 12 (hurricane force) based on its observable effects on water and land features. I've seen a couple places The smaller or micro (20- to 500-watt) turbines are used in a variety of applications such as charging batteries for recreational vehicles and sailboats.
