Delivery drone wannabees Amazon.com, Inc., Google and Wal-Mart Stores, Inc. have signed on to a government task force headed up by the Federal Aviation Administration (FAA) to help devise an identification and registration system for unmanned aerial vehicles (UAVs).

All three companies have thrown their weight behind drone development, and will formulate their recommendations for how the system would work, and which kinds of drones should be exempt, by November 20. Representatives of the companies will attend a three-day meeting later this week.

Currently, drones do not need to be registered in the U.S., but the FAA is growing concerned about the number of dangerous incidents involving them. The idea is that by registering each drone that takes to the air, it’ll be much easier to find and prosecute anyone who causes mischief.

The committee will be co-chaired by the FAA’s Earl Lawrence and Google’s Dave Vos, who currently leads the drone development project at Google X. Vos is receptive to the idea of some kind of identification system, having previously proposed that drones should constantly transmit their location to air traffic control at a NASA conference last summer.

Vos also proposed that drone pilots should file a flight plan and obtain approval before being allowed to take off. He suggested that drones use the ADS-B identification and broadcast system that’s already utilized by commercial aircraft, but it remains to be seen if his ideas will meet the approval of the FAA or other companies.

Several other well-known companies have joined the FAA’s task force, including drone makers 3D Robotics Inc., DJI Inc., GoPro Inc. and PrecisionHawk, as well as retail firm Best Buy Co., Inc.

Members of the public can make their own comments and submissions to the task force at the Regulations.gov website.
