Carrying a 50-lb. payload, the Firefly can fly for 3 hr.
Parallel Flight Technologies has received a key regulatory approval that allows it to begin commercial deployment of its heavy-lift, hybrid-electric uncrewed aircraft system (UAS) in the U.S.
The FAA granted the California-based company an exemption under Section 44807, a pathway that permits certain uncrewed aircraft to operate commercially before full certification. The approval clears the way for customers to deploy the company’s Firefly drone for industrial missions ranging from logistics to heavy-sensor operations.
Craig Stevens, CEO of Parallel Flight, says the exemption effectively unlocks the first stage of domestic commercial operations for the company’s aircraft. Parallel Flight ultimately expects to pursue additional authorizations—including Part 137 approvals for agricultural missions and potentially Part 135 approvals for logistics operations.
“The 44807 exemption gives users the ability to fly the aircraft in a commercial application, assuming they already have their own part 107 exemption,” Stevens said. “It will get us up and running domestically, and then we’ll figure out how to move into the Part 135 requirements from there.”
Parallel Flight says it has orders on the books but has not yet shipped aircraft to paying customers. Stevens said customers are now arranging financing and production planning following the exemption.
Parallel Flight’s Firefly is a hybrid-electric quadcopter designed for missions that require more endurance and payload capacity than battery-powered drones typically provide. The company says the aircraft can carry payloads up to 100 lb. and supply 2 kW of continuous inflight power to onboard systems. Carrying a 50-lb. payload, the Firefly can fly for 3 hr.
Stevens said that hybrid propulsion is gaining traction as operators run into the limits of all-electric drones in remote or infrastructure-poor environments.
“A few years ago, if you weren’t talking about purely electric drones, nobody wanted to hear about it,” he said. “But what people are realizing now is there are a lot of applications where electric drones just fall short. If you’re trying to scan a thousand-acre mine or cover large agriculture acreage, you simply can’t stay in the air long enough to do useful work.
“Those operators are carrying sensors in the 25- to 50-pound range, and they need to cover huge areas, and with electric drones that can mean multiple flights and multiple charging setups to finish the job,” he said.
Parallel Flight also sees defense as a major near-term market. Stevens said defense funding has been more available than wildfire-related funding over the last three years, even if the underlying technology development remains complementary across both sectors.
“All of our funding for the last three years has come from the defense side,” he said. “The availability of money on the defense side is a lot more prevalent than on the wildfire side. But the activities we’re doing are complementary between the two.”
That funding includes a $3.74 million Sequential Phase II Small Business Innovation Research award from the U.S. Office of Naval Research announced last year to develop a maritime version of Firefly. Stevens said current U.S. Navy work is focused on oceanographic sensing and other non-kinetic missions, while longer-term defense applications could include logistics from ship-to-ship and ship-to-shore.
Beyond the FAA exemption, Parallel Flight is pursuing inclusion on the Blue UAS list, a U.S. government-approved roster of drones that meet domestic sourcing and cybersecurity requirements. Stevens said the company expects that effort to take two to three months. The step has grown more important since new federal communications requirements took effect late last year.
The company has room to meet production needs for the first two years in its current facility, Stevens said, and has lined up a local contract manufacturer for higher-rate output if demand grows into the hundreds of units per year.
Stevens said the pitch to customers is straightforward.
“We really want people to think of our aircraft, really as a truck in the sky,” he said. “If you want to throw something on it and fly with it, you can do that.”
