The experimental delivery drones Google has been testing under Project Wing weigh less than 55 pounds (25 kg), can fly at speeds of up to 100 miles per hour (160 km/h) and reach elevations of up to 400 feet (120 m) using their multiple electric engines, documents obtained by the Guardian reveal.
The problem is, Google is obviously not a public institution like the military, state universities and police or fire departments the NASA program is meant to assist. For commercial companies, the Federal Aviation Administration (FAA) may issue waivers called “333s,” like the one Amazon obtained in April for research and development of its delivery drones for the Prime Air program.
The tests, planned for airspace over central California, might last up to half a year and involve transmissions on the LTE and 4G radio frequencies used by mobile phone companies. The ultimate goal is to make cell signals work for automated traffic control, with the potential of “generat[ing] new business opportunities for communications service providers and remov[ing] barriers to the broader deployment of [Unmanned Aerial Systems] UAS.”
Technologies similar to Project Wing are currently under development at Google’s X Lab, while wireless communications are being researched within its Project Fi along with Project Loon and Project Titan, intended for delivering web access using balloons and solar-powered UAVs.
Reflecting on concerns over airspace safety at the core of current FAA drone restrictions, the tech company wrote in its “333” exemption request that its aims include increased safety to the public.
“Google’s proposed UAS operations… will not adversely affect safety, but rather will provide an equivalent or greater level of safety than that provided by… other delivery methods… using trucks/cars/motorcycles or larger manned aircraft.”
