There will be 600,000 commercial drone aircraft operating in the U.S. within the year as the result of new safety rules that opened the skies to them on Monday, according to a Federal Aviation Administration estimate. The rules governing the operation of small commercial drones were designed to protect safety without stifling innovation, FAA Administrator Michael Huerta told a news conference. Commercial operators initially complained that the new rules would be too rigid.

Federal aviation officials estimate there will be 600,000 commercial drone aircraft operating in the U.S. within the year as the result of new safety rules that went into effect on Monday, Aug. 29, 2016.

Flying a drone for commercial purposes will no longer require a pilot's license, the Federal Aviation Administration announced in new rules released Tuesday. Drones flown in for-profit uses will no longer require a special permit so long as they weigh no more than 55 pounds, soar no higher than 400 feet and fly no closer than 400 feet from buildings or structures, the guidelines stipulate. Previous rules required commercial drone operators to have a pilot's license and apply for an FAA waiver – a tedious process believed to have steered many businesses to use drones without proper permission. The new regulation, which takes effect in August, will allow anyone over the age of 16 to fly a commercial drone so long as they apply for a remote pilot certificate, which requires passing an aeronautics test at an FAA-approved facility and undergoing a background check. That threshold is far lower than a pilot's license – a move likely to encourage greater commercial use of drones, industry experts predict.

WASHINGTON – After years of struggling to write rules that will both protect public safety and free the benefits of a new technology, the Obama administration is on the verge of approving routine commercial use of small drones. The Federal Aviation Administration is expected to announce as early as Tuesday the creation of a new category of rules for drones weighing less than 55 pounds (25 kg). The long-anticipated rules will mean drone operators would be able to fly without special permission. Currently, they have to apply for a waiver from rules that govern manned aircraft, a process that can be time-consuming and expensive. Since 2014 the FAA has granted more than 6,100 waivers and another 7,600 are waiting for approval. Many more small companies have been using drones without FAA permission, say industry officials.

The Federal Aviation Administration is predicting a bright future for the growth of the commercial and hobbyist drone industries after final regulations are approved. In an aerospace forecast report released Thursday, the FAA said unmanned aircraft systems will be the "most dynamic growth sector within aviation." It noted that venture capitalists have already sunk "considerable" funds into the industry in hopes of building early market share. Already, the FAA predicted that 1.9 million hobbyist drones will be sold this year, along with more than 600,000 commercial drones. The FAA predicts that 4.3 million hobbyist drones could be sold per year by 2020.
