An estimated 1.6 million drones were sold nationwide in 2015 — so the Salt Lake City International Airport is reminding new drone owners that they are required to notify it before flying a drone nearby.

The Federal Aviation Administration recently required owners of drones to register with that agency, and adopted rules requiring them to alert airports before operating a drone within a 3- to 5-mile radius of an air traffic control tower.

The FAA Salt Lake City Air Traffic Control Tower does not allow drones to fly within a 3-mile radius from it.

Airports without a control tower — such as the South Valley Regional Airport in West Jordan and the Tooele Airport — allow drones within a 5-mile radius, but only after prior notification to the airport.

Hobbyists planning to operate a drone within the restricted area must notify the airport 24 hours before flying the drone — and should be prepared to provide the time, location and duration of the drone flight.

If the proposed flight is deemed not to present a hazard, the airport will log the notification and allow the flight. To notify the Salt Lake City International Airport, Tooele Airport or South Valley Regional Airport, call 801-556-4082 or email Dave.Teggins@slcgov.com.
