As of Tuesday, about a quarter of the way through a 60-day public comment period, the FAA had received 380 comments from a cross section of interested parties including hobbyists, pilots, aviation organizations and those who want to exploit drones for commercial purposes, but to-date major organizations and lobby groups have not submitted their comments.
The FAA's proposed rules cover commercial flights of drones and allow them to fly at up to 500 feet at speeds of up to 100 miles per hour during daylight hours. The drone must be flown by a licensed drone operator -- a newly created certification -- and kept within visual line-of-sight at all times. Drones would always have to give way to other air traffic and could not fly over people except those involved in its flight.
The 500-feet ceiling is one area of debate, in part because it buttresses up to controlled airspace. Model aircraft are currently allowed to 400 feet, providing a slim buffer that drones shouldn't enter, said Tim Olson, who identifies himself as a private pilot. Another pilot observed the extra 100 feet isn't really needed for photography because most drones employ a wide-angle camera.
Another area of interest is the ban on night operations, which some want lifted for either "law enforcement, EMS and other qualified operators using IR equipment," said David Tillman of Georgia, or for photographers who want to take advantage of the better light at dusk and dawn.
"With front and rear lights on these aircraft, it is possible to keep them safe, in close range," wrote photographer Brett Lane of Ohio, who submitted an aerial photo of a sunrise or sunset, perhaps taken by a drone.
Some think the requirement for a license is too much.
"I'm concerned with the proposed cost of getting licensed to fly one of these things as part of my business will keep this kind of opportunity out of reach for me," said Larry Launstein Jr.
Some think it's too little.
"I want to see regulations that make safety a major concern. I recommend an actual flight test not just a written exam," said Chen Dubrin of California.
One anonymous comment proposed pilots shouldn't be required to get one while another hiding behind anonymity told the FAA to just "butt out" of drone flying.
But what good are the proposals without enforcement That's something that wasn't addressed by the FAA but noted in several of the comments.
"There is NO realistic possibility of actual enforcement of any restrictions on the location and especially, altitude, of these drones," wrote Fred Geiger of Santa Cruz.
One solution for keeping order in the skies and keeping track of where drones fly, proposed in several comments, is the use of ADS-B -- a system in use on many commercial aircraft that automatically broadcasts a location and identification on a set frequency. Another person called for prominent identification on the side of drones with an "N-number," the system used on commercial and private aircraft.
It's not just compliance with the FAA's rules that's up for debate, but the potential for invasion of privacy that may occur from drone photography. That's not strictly an FAA issue, but ideas came in anyway.
"The proposed rules should have extremely harsh jail and civil penalties for the invasion of privacy issues," wrote Jeffrey Aryan of California. "Such as a minimum of 15 years in prison for the first offense and a fine of 5 million dollars."
The public comment period is scheduled to close on April 24. Comments can be submitted through Regulations.gov in the FAA-2015-0150 folder.
