Flight Gauges

About

Barometric Altimeter with Vertical Speed Indicator, and GPS ground speed indicator, in knots, mph and kph. Attitude Indicator and Compass. * Current pressure readings * QNH setting with mbar and inHg units * Alternate GPS altimeter mode * Altitude is displayed in feet and meters Warning: To use the Barometer, you need a device that supports it (iPhone 6 or later), otherwise the app will continue in GPS mode. DISCLAIMER: These instruments should never be used as primary source of orientation during flight. Drift and sensor error are expected. Speed is always GPS Ground Speed and depends on correct GPS signal. Altimeter can be GPS or Barometer based. If Barometer is selected, the source is cabin air, which usually resents a lower than outside pressure. Usage in pressurised cabins will present obvious errors.
