HAL’s Hawk I flies with RTOS
Hindustan Aeronautics Limited (HAL) has successfully completed the first flight of its Hawk I training aircraft with its newly developed Real Time Operating System (RTOS), the company announced on 7 February.
The RTOS has been developed by the company in India and certified by the Center for Military Airworthiness and Certification.
The RTOS is the system software which provides a standard run-time environment for real-time applications execution. The system has been designed for safety-critical and mission-critical avionics systems. The advanced modules such as network stack and file system have been co-developed with Indian Institute of Technology, Kharagpur, which also carried out formal method based verification of the RTOS kernel.
The complete operational flight programme, including real-time sensor data processing, navigation algorithm computations, controls and display management and interface management, was ported and the RTOS met all its design requirements during the flight.
Suvarna Raju, CMD, HAL, said: ‘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.’
The plan is for HAL's RTOS to become the standard RTOS for any future avionics systems developed in India, to remove reliance on imported systems.
