More complex combat-helicopter engines require large increases in diagnostic/prognostic capability, which also require a greater number of sensor inputs to the electronic engine controls (EECs.) At the same time, military helicopters face the increased need for resilient cybersecurity. Together, these trends drive the need for multicore processors in the EECs, despite the challenge of ensuring real-time determinism when different processor cores compete for the same shared resources. The foundation for a solution to both challenges is a certified, hardened real-time operating system (RTOS) with multicore interference mitigation. Multicore interference mitigation enforces real-time determinism even when multiple processor cores are vying for access to the same processor resources.

NATIONAL HARBOR, Md. -- MOSA Industry & Government Summit & Expo.  Green Hills Software and Mercury Systems announced that they have entered the verification phase for providing DO-178C and AC 20-193 (formerly CAST-32A) airworthiness evidence for the Green Hills INTEGRITY-178 tuMP safety-critical real-time operating system (RTOS) running on quad-core 11th- gen Intel Core i7 processors (formerly Tiger Lake).

SANTA BARBARA, Calif. Green Hills Software announced that its INTEGRITY-178 real-time operating system (RTOS) is deployed in the engine control units (ECUs) from Triumph Group, Inc. (TRIUMPH) for a number of different U.S. military helicopters -- including the AH-64D Apache, CH-47D/F & MH-47D/F/G Chinook, UH-60L/M/V Black Hawk, HH-60 Pave Hawk, MH-60 Jayhawk, and SH-60 Sea Hawk -- in order to meet RTCA/DO-178B Design Assurance Level A (DAL A) certification. 

Operating an aircraft in a degraded visual environment (DVE) is one of the most challenging and stressful tasks for a military pilot, particularly during landing. There are many causes of DVE conditions, including naturally occurring smoke, fog, smog, clouds, sand, dust, heavy rain, blowing snow, darkness, and flat light. Those conditions can happen in combination, and some of the most challenging DVE is induced by the aircraft itself, creating a brownout or whiteout from dust, sand, or snow. Mitigation solutions for the problem of operating aircraft in a DVE fall into a few broad categories: enhanced vision, synthetic vision, and a combination of the two.

SANTA BARBARA, Calif. Green Hills Software says that fixed-wing autonomous flight company Merlin (Boston, Massachusetts) will use the Green Hills Software INTEGRITY-178 tuMP real-time operating system (RTOS) for its autonomous flight solution, running on the PU-3000 multicore avionics computer from CMC Electronics (Montreal, Canada), which will host the flight-control software that enables autonomous flying.

Almost every part of our modern economy depends on the Global Positioning System, or GPS. For example, agriculture, construction, mining, rail transportation, and search and rescue all rely on the accurate position, navigation, and timing (PNT) enabled by GPS. An even broader set of industries – communications networks, banking transactions, financial markets, and power grids – rely on GPS for precise time synchronization, to such an extent that most systems would cease working without it. Alternative navigation (ALTNAV) systems can supplement GPS systems in GPS-denied environments using internal clocks and onboard sensors, and those ALTNAV systems should be protected from cyberattacks as well.

SANTA BARBARA, Calif. Green Hills Software announced that its INTEGRITY-178 tuMP safety-critical real-time operating system (RTOS) will be used in the replacement multifunction controls and displays (RMCD) on the U.S. Air Force's C-5M Super Galaxy strategic transport aircraft.
