SYSTEMS

Configure your flight.

Settings apply immediately. No API keys or subscriptions.

Rendering

Real-world vegetation and buildings use loaded OpenStreetMap footprints. Missing map features are not invented.

Atmosphere

Camera and controls

The mouse controls the camera. Fly with the keyboard or gamepad. Scroll to zoom; aim at the cockpit throttle and scroll to adjust power in 10% steps.

Audio

Cockpit audio filters and softens engine noise. External views retain exhaust noise. Audio is synthesized.

Real-world scenery

Start the local server for reliable loading. Open the localhost URL, not the HTML file. Geographic services are best-effort and can be unavailable.

No API keys, accounts or paid services are required. NASA imagery has regional resolution; the public-domain basemap remains available if imagery fails.

Checking transport…

Unavailable elevation is labeled flat terrain; no mountains are invented. Missing map tiles do not pause physics.

CONTROLS

Looking is not steering.

In the cockpit, C toggles the interaction crosshair. Aim at a control and click; F2 shows labels. With the mouse unlocked, click controls directly. Escape releases the pointer and opens the menu.

Quick start

Takeoff. Release the parking brake with K, increase throttle and accelerate down the runway. At sufficient airspeed, hold S or ↓ to raise the nose. Retract the gear with G after liftoff.

Landing. Choose the Approach start. Align with the runway, gear down, with controlled airspeed. Reduce sink before touchdown. Set idle with − and hold Ctrl to brake after landing.

Energy. Afterburner increases thrust but does not instantly stop a descent. Recovery needs airspeed, altitude and suitable attitude. Pull progressively rather than holding a stalled nose-high attitude.

Gamepad. Left stick: flight. Right stick: look. LB/RB: throttle. RT: gun. A: missile. B: gear. Y: camera. LT: brakes. D-pad: rudder.

Experimental game simulation. Not a certified F-16 model or real flight procedure.
