Welcome to Aether FIR ATC Simulator Take control of the airspace in Aether FIR ATC Simulator , a minimalist yet highly interactive Air Traffic Control (ATC) simulator. Your mission is simple but unforgiving: safely guide aircraft through your sector, manage their altitudes, speeds, and headings, and prevent mid-air collisions. Key Features: Deep ATC Mechanics: Issue direct commands via the Track Data Block (TDB). Change Clearances for Flight Levels (CFL), assign specific headings (vectoring), adjust speeds, and set climb/descent rates. Multiple Game Modes: Open Sector (Sim): An endless sandbox mode. Manage a continuous, randomized flow of arrivals, departures, and overflights. Campaign: Hand-crafted scenarios with specific challenges. Face strict separation rules where a single mistake means game over. Interactive Training: Learn the ropes with a comprehensive, step-by-step tutorial. Advanced Controller Tools: Utilize the Extended Label Window (ELW) for flight plan details, dynamic measuring rulers, and predictive speed vectors. Pre-clearances: Plan ahead by issuing conditional commands to uncontrolled aircraft before they cross your boundaries. STCA System: A built-in Short Term Conflict Alert actively monitors the airspace and warns you when aircraft breach minimum separation limits (5 NM / 1,000 FT).
