Thales UK Aerospace chief sees large civil UAVs in years ahead

One of the key players in the primary UK programme aimed at enabling the use of UAVs in civil airspace believes that unmanned cargo aircraft will be operating within a decade.

Thales UK Aerospace managing director Richard Deakin is confident that the potential savings will drive development of such aircraft, and that regulators will permit their use.

His optimism is partly driven by the encouraging progress of the £32 million Government/industry Autonomous Systems Technology Related Airborne Evaluation & Assessment (ASTRAEA) programme aimed at enabling routine UAV flight in UK civil airspace.

Interviewed in London, Deakin said: “In ten years time we will see unmanned cargo aircraft. If you look at the cost savings that could be made if you combine UAVs with, for example, free-flight then you start to look at significant cost-savings.

“I don’t think cargo UAVs are too pie in the sky. It might need a dedicated airport. And using satcoms might be an option that you would want to bring in. But in any case you could tell the UAV to fly to a certain place and land if it loses the link. It can do category IIIC (zero visibility and ceiling) landings.”

He suggests that the greater savings available will make long-range services the most attractive and suggests the Pacific is an area that would be of interest to operators.
“There is no reason not to have [trans-Pacific services] on quite a quite regular basis,” he says., adding more generally: “Once you have got the regulatory issue out of the way then over the next five years you will see workable programmes coming together.”

Deakin does not think that recent UAV accidents will damage progress towards their wider use, suggesting that the losses have been more due to on-board system failure than to datalink or control issues.

He believes that remote control of larger aircraft – such as Airbus or Boeing types – may in fact be easier to approve because in those machines “the integrity of the systems have been proven”.

The bigger issue, he says, is the development of the “see and avoid” concept needed to ensure separation from other aircraft.

ASTRAEA is examining a range of techniques relying on electro-optics , infrared sensors, and millimetre-wave (MMW) radar.

Deakin says: “The real challenge is how do you get that bubble around the UAV. A lot of the systems have a specific field of view, so the question is how we manage the aircraft in a kind of awareness bubble.”

He believes that MMW radar “will definitely have a role” because “potentially that can provide omni-directional coverage”, but adds: “It will be around the most cost-effective solutions. You could solve it today, but affordability is important.”
