The U.S. Navy is rethinking prime contractor Northrop Grumman’s selection of an Exelis-built collision avoidance radar for the unmanned MQ-4C Triton maritime surveillance aircraft.

However, “we’ve made a decision to pause on the development of that capability,” Capt. James Hoke, the Navy’s Triton program manager, said at the Unmanned Systems 2013 conference in Washington, D.C.

Rockwell Collins’s next-generation TTR-2100 traffic alert and collision avoidance system (Tcas II) for transport aircraft has achieved FAA certification. The new system, which provides NextGen traffic surveillance in a lighter and more capable unit, is available for Boeing aircraft as a forward-fit and retrofit solution. Airbus and other aircraft types will follow soon. Both the TTR-2100 and the soon-to-be certified TTR-4100 for helicopters and business and regional aircraft meet the emerging requirements of NextGen airspace.

Purdue University pilots flew an Embraer Phenom 100 partially powered by a mix of biofuel and jet-A to EAA AirVenture Oshkosh on Friday. The biofuel blend–a mixture of a camelina-based biofuel and jet-A provided by the U.S. Air Force–was used to power one of the Phenom’s engines; the other engine ran on jet-A alone. Key flight performance measurements were recorded and will be studied.

With launch of the first next-generation GPS III satellites planned for 2016, the DOD is looking for ways to reduce costs in line with today’s budget realities while ensuring the utility airspace users expect in the future.

With the continuing strains on the U.S. national budget and the possibility that the Administration’s sequestration program could last for several more years, Pentagon planners are said to be worrying that the costs of the future GPS III system could become out of reach, despite its major advances and the need to have modernized replacement satellites ready to be deployed as the orbital lives of current satellites end.
