NEW HAZARDS ON THE HORIZONS……MET TOWERS
Notice Number: NOTC2278

MET towers (Meteorological towers), are used to gather wind data necessary for site evaluation and development of wind energy projects. They can be erected very rapidly and may be on site from a few days to up to a year or longer. Towers generally range in height from 30, 50, 60 and 80 meters tall. Any tower less than 200 feet in height is not required by regulation to be lighted. At this time there is no standardized notification system in place to indicate when and where these towers are erected.

These are not posted in any Airport Facility Directory, NOTAMS, etc. unless they interfere with airport operations. BE ON THE OUTLOOK FOR THESE HAZARDS…!
