Detailed explanation-1: -Hard RTOSes are normally used in systems that require important time-based executions, such as in airplane sensors, autopilot systems or medical devices.
Detailed explanation-2: -“ARINC 653 (Avionics Application Standard Software Interface) is a great standard that has stood the test of time: it has been around for 20 years now and has gone through minor revisions, but it has been deployed to many, many aircraft” (Product Focus).
Detailed explanation-3: -What is Autopilot? An autopilot is a software or tool that can only manage the aircraft under certain conditions using the vehicle’s hydraulic, mechanical and electronic systems. This system, which can follow the flight plan, can stabilize speed and height as well as the location of the front of the aircraft (heading).
Detailed explanation-4: -A real-time operating system (RTOS) is an operating system with two key features: predictability and determinism. In an RTOS, repeated tasks are performed within a tight time boundary, while in a general-purpose operating system, this is not necessarily so.
