07 February 2018

India’s Hindustan Aeronautics Limited (HAL) has carried out the first flight of a Hawk-i advanced jet trainer fitted with an indigenously developed real-time operating system (RTOS), the state-owned aerospace and defence company announced on 7 February.

“It is the first indigenous RTOS that has been developed in the country from scratch,” said the company in a statement, adding that it is also the first instance that an indigenous RTOS has been certified by the Bangalore-based Center for Military Airworthiness and Certification (CEMILAC), which is part of the government-run Defence Research and Development Organisation (DRDO).

“The RTOS’ performance has been validated on the mission computer of HAL’s Hawk-i trainer aircraft. The complete operational flight programme, which includes real-time sensor data processing, navigation algorithm computations, controls and display management and interface management, was ported, and the RTOS was able to meet all its design requirements during the flight,” said the company.

The recently developed RTOS was described by the company as “the system software which provides a standard run-time environment for real-time applications execution in a safe and reliable manner”.

“The RTOS is a key technology for concurrent execution of multiple applications and optimal use of hardware resources, which is of paramount importance for increased complexity of modern avionics software,” it added.

HAL said that its RTOS provides a comprehensive features set based on the international specification – ARINC-653 – to support an integrated modular avionics (IMA) architecture. Key features include address, space and time partitioning, priority pre-emptive process scheduling and health monitoring.
