Predator B successfully trials new DAA system

One of the main contenders for Project AIR 7003 Phase 1 has successfully conducted a flight through the US National Airspace System (NAS) using a detect and avoid (DAA) avionics system.

One of the main contenders for Project AIR 7003 Phase 1 has successfully conducted a flight through the US National Airspace System (NAS) using a detect and avoid (DAA) avionics system.

A NASA-owned General Atomics Aeronautical Systems (GA‑ASI) Predator B unmanned aircraft system (UAS) – known as Ikhana – took flight through the NAS after taking off from southern California.

The DAA system installed on Ikhana, enabled the UAS to meet the FAA’s 14 CFR 91.113(b) requirement to “see and avoid” other aircraft during flight.


The DAA system combines automatic collision avoidance with the ability for the pilot to remain ‘well clear’ of other airspace users. Its subsystems include a GA-ASI-developed airborne radar, a TCAS II and DAA tracking capability from Honeywell, automatic dependent surveillance-broadcast (ADS-B) IN/OUT, and a conflict prediction and display system.

“Our goal of producing UAS that can be certified to fly in non-segregated airspace took a big step forward today,” said Linden Blue, CEO, GA-ASI.

“[The] successful flight is testament to the strong relationship that we have with the FAA, NASA’s Armstrong Flight Research Center and Honeywell to produce the definitive standard for unmanned aircraft operation in congested airspaces.”

David Alexander, president of aircraft systems at GA-ASI, said the DAA system is a game changer for manned and unmanned aircraft.

"Our DAA system is more capable than the collision avoidance systems required on today’s commercial manned aircraft and we believe it far exceeds the average pilot’s ability to ‘see and avoid’,” said Alexander.

“The predictive capabilities our system employs create a safe environment for manned and unmanned aircraft to fly together in the NAS.”

GA-ASI has been developing the DAA system with internal funding for inclusion on all its aircraft. In particular, the new MQ-9B SkyGuardian is provisioned to include the DAA system as a customer option, and the company’s MQ-25 offering also includes the opportunity for the US Navy to incorporate DAA.

The DAA system for MQ-9B is designed to comply with the FAA-designated DO-365 - minimum operational performance standards for detect and avoid systems.

GA-ASI's Predator B UAS is considered the leading contender for the AIR 7003 Phase 1 project, which is calling for a medium-altitude long-endurance (MALE) UAS, colloquially known as self-piloted 'killer drones'.

GA-ASI has formed partnerships with local Australian companies, known as Team Reaper Australia.

The team is made up of Cobham, Raytheon Australia, CAE Australia and Flight Data Systems, TAE Aerospace, Rockwell Collins, Ultra Electronics Australia, Airspeed and Quickstep Holdings.

Israel Aerospace Industries (IAI), Israel’s largest defence company and a supplier of UAS solutions, has also bid for the project, offering its Heron TP capability, the armed and improved variant of the recently withdrawn Heron.

However, questions around the project surfaced last year when IAI claimed the Department of Defence was blocking out the company from bidding for the project, which is listed as contestable on the Defence Integrated Investment Program (DIIP).

"This is one of the problems we have with this process, the lack of transparency," vice president of IAI's military aircraft group Shaul Shahar told Defence Connect last August.

"This is a contestable project, according to the IIP. Now, there [are] two suppliers/two countries companies that [have] this capability to support the requirements in this project. As a company we have a significant footprint all over the world with our product ... We think that we have a solution that can benefit of Australia.

"Because of the lack of transparency in this process, and it's very weird to us because we expect that there will be a process including evaluation, risk analysis, according to all the stages that they need. At the end they can decide to go to sole source, but during the evaluation, we thought that they need to check what other alternatives that are on the table and to have all the data needed to do this analysis.

"If they (RAAF) didn't approach us, and up to now haven’t given us the chance to know what questions need to be answered, what information we need to bring to the table, it means they are moving forward without going through all the right stages in their stated process."
