National Agricultural Aviation Association releases its Aerial Application Industry Survey of Part 137 operators and ag pilots, which shows that operators are embracing a range of methods and technologies, such as GPS (utilized by 99% of pilots by then) and flow-control valve technology, to increase efficiencies and minimize drift. The data is used to preserve the aerial use of a crop protection product and/or prevent aerial use restrictions for a crop protection product while still ensuring environmental and occupational safety.
