ONE LIVE WORLD. AIR · ROAD.
A unified real-world simulation shell: fixed-wing flight, serious helicopters, real-road driving, live weather, photorealistic 3D geography, persistent navigation, Living World traffic and an adaptive performance system that protects nearby world quality first.
AIRCRAFT BEHAVIOR IS DRIVEN BY THE ORIGINAL .DAT PARAMETERS AND CONVERTED .DNM GEOMETRY. LIVE WORLD DATA STREAMS SEPARATELY.

SIMULATION EXPERIENCE
Realism without guesswork
Choose how much assistance you want. Physics stays simulation-focused; these presets change control assistance, physiology presentation, world budget and helicopter stability aids. Advanced settings remain available below.
WHAT DO THESE SETTINGS MEAN?
WORLD DETAILPhotorealistic uses streamed real-world 3D; OSM is lighter; Terrain Only is the recovery option.GRAPHICSControls the visual performance budget. It does not change flight physics.STREAMINGControls how aggressively distant world data is requested. Nearby buildings always have priority.FLIGHT ASSISTFBW adds envelope protection, SAS damps rates, RAW removes stability assistance.DAMAGE / GRealistic enables component impacts and pilot/structure G consequences.AIRSPACEControls simulated aircraft contacts, not road traffic or world geometry.

ROAD MODE
Vehicle & Road Deployment
ROAD now always enters with a visible 3D vehicle. Real road geometry is preferred; if the provider is temporarily unavailable, free-drive fallback keeps the mode usable instead of failing silently.

v9.8.0 FLIGHT CORE: authoritative runtime state, fail-safe essential HUD, persistent real cockpit loading, faster retained-tile maps and domain-safe AIR / HELICOPTER / ROAD transitions. 9.5 FOUNDATION: Living World presentation work is cadence-capped away from the 120 Hz AIR hot path; ROAD nearest-segment lookup uses a bounded spatial index with pressure-aware surface sampling; the tactical map supports drag-pan, panned-center waypoint placement and bounded tile retries. FOUNDATION: Burn-in health tracking, device-bound controller mappings, disconnect neutralization and richer diagnostic exports. WORLD / HELICOPTER: Route-corridor preloading, persistent cache controls, heliport-aware navigation, stricter near-field readiness and helicopter skid-ground handling. HELICOPTER / SCALE: Physical 1:1 aircraft scale, rotor inertia/ETL/VRS/ground-effect helicopter model, live rotor animation, aircraft-type filtering, address-to-waypoint map focus, user FOV control, refined PBR aircraft shading. RELIABILITY: Shadow DOM/local-cache moving map, synchronized transparent map overlay, local tile proxy/cache, enhanced aerodynamic energy model, living airspace, missions, traffic alerts, pitch trim, flight-computer telemetry and performance-separated scheduling.
