Editing ATC Linux

'''ATC Linux''' (Air Traffic Control Linux) is a **highly specialized, hard real-time server distribution** based on **RHEL/CentOS** designed for mission-critical industrial control systems, particularly in aviation and infrastructure.

== Base and Philosophy ==

* '''Base Distribution:''' Based on **RHEL/CentOS**, chosen for its extreme reliability, long support cycles, and the availability of a certified **Real-Time kernel** suitable for industrial use.
* '''Goal:''' To provide an operating system with guaranteed, minimal response latency (microseconds) that can reliably execute time-critical control algorithms, essential for safe operation of infrastructure systems.

== Core Features ==

* '''Real-Time Kernel:''' The defining feature is the use of a fully preemptible, **hard real-time kernel** (often using the PREEMPT_RT patch set) to ensure deterministic execution of time-sensitive tasks, regardless of system load.
* '''Isolation and Security:''' The system is heavily secured, often using **SELinux** and strong network separation, and is stripped of non-essential services to prevent unexpected delays or security breaches.
* '''Industrial Protocols:''' Includes pre-configured libraries and tools for common industrial control and network protocols (e.g., MODBUS, SCADA, specialized radar data formats).
* '''Target User:''' System integrators and engineers working on critical infrastructure, such as air traffic control, nuclear power plant control, or high-speed financial trading systems where timing is paramount.
