AVIONICS09 Conference

Strict Standards: Only variables should be passed by reference in /home/defensef/public_html/components/com_zone/handleHTML.php on line 623
: 11 February, 2009  (New Product)
The Forthcoming AVIONICS09 Conference will host six different conference sessions; the fourth of which has had details released.
This session, which will be held on March 12th 2009 - 09.00 hrs to 10.30 hrs will have
papers presented by speakers from Alenia Aeronautica, and Eurocontrol Military Expert,
and will cover the development of standards for different UAV systems, and UAS/ATM
compatibility issues.

Abstracts from each paper are listed below.

Development of a standards based Mission Computer for different UAV Systems
Alenia Aeronautica had the challenge of developing the On-Board Mission Computer for the Sky-X and Sky-Y Unmanned Aerial Systems. These are very different UASs, the Sky-X being a non-stealth jet unmanned aircraft that is quick, easy to manoeuvre and suitable for short and quick fighting missions, and the Sky-Y being designed to fly at medium altitudes in longer endurance military and civil missions. In order to standardise on both systems, Alenia took a methodical and standard based approach in order to save time and expense when developing and re-using applications between the two UASs. Due to the civil requirement of Sky-Y, the development also had to take into account safety certification issues under EASA and FAA guidelines, a challenge in that these are evolving standards.

In order to meet these demanding requirements, Alenia specified an ARINC 653 software architecture and RTCA DO-178B as the software safety standard. This paper discusses how Alenia developed a plan to prototype on a federated architecture with a goal of partitioning the software applications in order to move to an IMA system as the project developed. It discusses how this application partitioning allowed Alenia to quickly and easily move from the prototype to an ARINC 653 environment using COTS technology and then re-use the technology on a second UAS project.

UAS represent the next major advance in aviation. Moreover, UAS which meet ATM
requirements will be regarded as legitimate airspace users alongside manned aircraft.
However, this requires that UAS fit the existing system rather than the system being
adjusted to accommodate UAS. In the crowded skies of Europe, this represents a major challenge that will not be overcome without Avionics support. EUROCONTROL is at the heart of efforts to integrate UAS with other airspace users. It has already published a set of ground-breaking ATM specifications for military UAS flying as OAT outside segregated airspace. Indeed, these specifications are likely to provide the ATM blueprint for the operation of all UAS outside segregated airspace. Building upon this, EUROCONTROL is now embarked on a four-year UAS work programme that is intended to embrace civil UAS and UAS flying general air traffic. Its ultimate objective is the transposition of UAS ATM operational requirements into a comprehensive set of globally inter-operable UAS certification and operational approval criteria. Activity within the programme will aim to ensure that airspace requirements form the basis for UAS performance standard and certification specifications that are being developed by other bodies such as EUROCAE, NATO and EASA. EUROCONTROL is therefore coordinating fully with these agencies, plus others such as ICAO and the FAA. The integration of UAS into European non-segregated airspace will be an evolutionary and incremental process, whereby usage will increase as confidence in UAS safety and reliability grows. Thus, it can be expected that current VLOS flight will extend to RLOS and beyond with the establishment of appropriate regulatory frameworks and the development of the necessary supporting technology.
