Flight system

Rockwell Collins has selected LynuxWorks’ LynxOS-178 real-time operating system (RTOS) for the Royal Air Force of Oman’s (RAFO) C-130 military transport aircraft avionics upgrade programme.

The LynxOS-178 operating system will be used in the Rockwell Collins Flight2 avionics management system, which is scheduled to be installed onboard RAFO’s three C-130 aircraft, as part of a contract received in April 2013.

The Flight2 avionics management system is expected to provide the aircraft unrestricted access to global airspace and address communication, navigation, surveillance/air traffic management (CNS/ATM) airspace requirements.

LynuxWorks VP Robert Day said the use of LynxOS-178 in the Flight2 system marks the latest example of its pedigree in critical avionics flight deck programmes.

"This is a testament that an open standards-based operating system can help maximise software reuse in airborne systems and can significantly reduce the time and cost of platform development and its subsequent certification," Day said.

The upgrades also include installation of new primary flight displays, advanced flight management system, autopilot, communication radios, navigation sensors and surveillance systems, including multiscan hazard detection weather radar, traffic alert collision avoidance system, terrain awareness, and warning system and digital maps.

"The system has successfully been installed on more than 100 C-130s of international military customers worldwide."

In addition to supporting growth to controller pilot data link communication (CPDLC), the Flight2 system improves the aircraft’s operational capabilities by offering an open systems architecture that combines flight operations with navigation and guidance functions and supports future growth requirements.

Featuring an Ethernet-based integrated processing center (IPC) with flight management capabilities, the system has successfully been installed on more than 100 C-130s of international military customers worldwide.

Installation and integration work is scheduled to be carried out by ST Aerospace, the prime contractor for the upgrade programme, at its facility in Singapore.

Powered by four Allison AE2100D3 turboprop engines, the C-130 Hercules is designed to conduct airborne assault, search-and-rescue, scientific research support, weather reconnaissance and aerial refuelling, as well as maritime patrol and aerial firefighting operations.
