PennDOT’s Bureau of Aviation has developed a new tool for pilots that have low altitude flying requirements — a web-based, interactive map depicting Meteorological Towers (MET) and other tall structures in Pennsylvania.
The map of METs, which can be found at the bureau’s webpage, provides pilots with useful flight information and adds an additional layer of protection in instances where environmental conditions may hamper visibility, such as at night or in poor weather, state aviation officials said.
MET towers can be erected quickly and, depending upon their location, without notice to the local aviation community. Because their height is typically within 200-feet above ground level, developers are not always required to notify the FAA or the state of their presence, nor adhere to the marking and lighting standards required for higher structures. Pilots are often unaware of these hazards and may have difficulty seeing METs from the air, state aviation officials said.
