AirHorizon: Attitude Indicator1.9.0 - App Store

AirHorizon is a simple, responsive aviation instrument simulator built around an artificial horizon with real-time motion.

Designed for pilots, student pilots, and aviation enthusiasts, it helps you visualize pitch and roll, monitor climb and descent, explore cockpit-style HUD layouts, and better understand aircraft attitude using your device or compatible external telemetry.

Features:

- Artificial horizon in portrait and landscape modes with smooth, responsive pitch and roll movement
- Speed and altitude tapes
- Heading tape with marker
- Variometer with visual indication and audio cues for climb and descent
- Variometer operation in the background or with the screen locked when sound is enabled
- Variometer input from device sensors or a supported external data source
- Adjustable variometer units, with sensitivity and response settings for device sensor input
- Modern pitch and roll boxes
- Night Vision HUD mode
- External flight telemetry over UDP
- Director Mode indication when using a supported external data source
- Adjustable instrument layout and display tuning
- Aircraft symbol overlay
- System status indicators
- One-tap calibration for pitch and roll alignment

External telemetry and compatibility:

External telemetry was tested on iOS and iPadOS with X-Plane 11 and X-Plane 12, and on iOS with Condor 3. All simulators ran on macOS; Condor 3 ran through CrossOver.

AirHorizon is an independent app. Neither AirHorizon nor its developer is affiliated with the developers of X-Plane, Condor, or CrossOver.

X-Plane and Condor 3 are used here as setup examples. Other applications may also work if they transmit flight data over UDP in a message format supported by AirHorizon. Using UDP alone does not guarantee compatibility.

Available readings and features depend on the data provided by the external source. The guide in Settings > External Source explains network configuration, supported telemetry, and variometer setup.

Important for iPad:

Enable Orientation Lock to prevent the instrument screen from rotating while moving the device.

Disclaimer:

AirHorizon is designed for simulation and familiarization purposes. It is not a certified aviation instrument and should not be used as a primary flight reference. Use at your own risk.
