"I evaluated a number of companies and eliminated most of them due to reasons such as a lack of RTOS features, company inexperience, no prior certification of their RTOS in an avionics product, or the inability to get technical support on the phone," said Dean Levi, principal engineer at PENTAR Avionics. "This narrowed it down to a couple of companies from which it was determined that Nucleus and the supporting packages met all of our requirements and desires."

"We are very pleased with our decision to use Nucleus PLUS and supporting packages," said Mr. Levi. "Our product is currently in the certification process and operates very efficiently with Nucleus."

Nucleus Chosen for PENTAR Avionics' CMS-1000

PENTAR Avionics' state-of-the-art development facility and headquarters is located in Seattle, Washington with a sales and support office in Kansas City, KS. PENTAR specializes in the development of airborne data communications for both the flight deck and the cabins of business and regional aircraft. With nearly 15 years of experience in providing complex avionics systems to the aviation industry, PENTAR delivers total solutions offering high performance, durability and reliability.

The CMS-1000 communications management system

The CMS-1000 is a complete communications system integrated into a small panel mount within a cockpit of an aircraft. Combined with the CMU-200 communication management unit and the CDU-200 multi-purpose ARINC 739 display, the CMS is a complete unit needed to support aircraft to ground communication networks.

The system provides all necessary aircraft information to the ground operator such as aircraft position, engine data, air data, fuel information, and many other aircraft parameters. The CMS-1000 also supports a choice of bi-directional communication media such as SATCOM, VHF, and airborne telephone and interfaces to peripherals such as flight management systems, printers and data loaders.

Nucleus Selected for the CMS-1000

The decision to choose an RTOS boiled down to several requirements. One important factor for the CMS project was that the RTOS had to be full featured, including the ability for partitioned memory, and it had to fully support the Motorola PowerPC 860 microprocessor. Access to the software's source code for customization and certification was also essential. Additionally, friendly customer service and responsive technical support would make a critical difference.

PENTAR also placed great significance on the experience of the RTOS company within the embedded industry. Mentor Graphics has been an established leader for more than a decade and supports that statement with market proven products.
