Emergency Backup Flight Instruments
SkyHUD
Your iPhone is a glass cockpit.
⚠ For reference only — not FAA / ANAC certified
Your iPhone is a glass cockpit.
Every instrument is driven by real sensor data from the iPhone's barometer, accelerometer, gyroscope, magnetometer, and GPS. No internet. No simulation. Real readings.
Kalman-filtered pitch and roll with vibration compensation per aircraft type. Roll arc, pitch ladder, slip ball. In landscape, the AI fills the entire screen — the camera shows through, aligning virtual and real horizons.
Barometric altitude in feet from the iPhone's pressure sensor. Adjustable QNH in hPa and inHg. Accurate to ±12 feet relative, matching the Bosch BMP280 sensor specification.
Indicated airspeed estimate in knots, derived from GPS ground speed corrected for estimated wind. Ground speed displayed separately. Dual-frequency GPS on iPhone 12+ for sub-meter accuracy.
Vertical speed in feet per minute and meters per second. Calculated from barometric pressure changes with weighted averaging. Color-coded: green for climb, red for descent.
Magnetic heading from the magnetometer with circular averaging for stability. Mini compass rose with north indicator. Cardinal direction display. Three-digit format with degree symbol.
Turn rate in degrees per second with standard rate indicator. Real-time G-load with max recorded. Wind speed and direction estimated from ground track analysis during turns.
No other backup instrument app overlays flight data on the live camera. SkyHUD Aviation does — creating a true head-up display experience when mounted in the cockpit.
The rear camera provides a live background. In landscape, the Attitude Indicator's transparent sky and ground overlay align with the real horizon visible through the camera. Mount the phone in the cockpit and you have a real HUD.
One tap switches all instruments to red lighting — preserving your night vision during night flights. Every label, value, and indicator shifts to red spectrum. No white light leakage.
Two-stage filtering: low-pass vibration filter tuned per aircraft type (helicopter, piston, turboprop, jet, glider, ultralight) followed by a Kalman filter for smooth, responsive attitude data.
Record the screen to capture the camera view with the instrument overlay. Saved to your photo library as video. The instrument data becomes part of the recording — like a dashcam for pilots.
SkyHUD Aviation was designed for the cockpit — including the expectation that it works in airplane mode with zero external dependencies.
SkyHUD Aviation is developed by Musicamania Tecnologia. For questions, feedback, or bug reports, reach us directly.

support@musicamania.com.brYes. SkyHUD Aviation works entirely offline. All sensor processing runs on-device. It works in airplane mode — which is exactly where you'll use it.
The iPhone's barometer provides ±0.12 hPa relative accuracy (Bosch BMP280), translating to approximately ±12 feet. Set the correct QNH for accurate MSL readings. GPS altitude is also available as a cross-reference.
No. SkyHUD Aviation is designed as an emergency backup reference, not a certified flight instrument. Always rely on your aircraft's certified instruments for primary navigation. A disclaimer is shown on every launch.
"Always" permission keeps GPS active during long flights even if the screen locks briefly. You can choose "While Using" instead — GPS will work while the app is visible but may lose lock if the screen turns off.
Yes. The two-stage Kalman filter was specifically designed for aircraft environments. The low-pass filter is tuned per aircraft type — helicopter (20 Hz rotor), piston single (25 Hz), turboprop (50 Hz) — removing engine vibration from the attitude data.
The rear camera feed is displayed as the background layer. In landscape, the Attitude Indicator's sky and ground are semi-transparent, overlaying the camera view. When the phone is mounted facing forward, the virtual horizon aligns with the real one.
