Airborne Flight Instrument
Henri van Bommel
This app is an intelligent flight instrument that reads altitude. It is designed for devices that contain a barometer. This includes iPhone6, iPhone6s, iPhone6 Plus and iPhone6s Plus models running IOS 8.0 or later. For altitude reading it automatically retrieves the QNH or AS Altimeter Setting from the web and uses it in combination with the pressure sensor (barometer) to determine the actual altitude. You can either select an ICAO METAR station, like EHAM or KJFK for Schiphol and JFK airports, or enter the QNH directly in the app. It is ideal for a number of air sports to be used as a backup. Besides altitude and flight level this instrument also displays true heading and speed. The indicated values are displayed using a large font so they can easily be read from a distance. When backgrounded, this app is inactive to save power.
