Altitude APPLICATION description
Altitude uses the pressure sensor in your Android device to provide altitude and rate of climb information displayed on replica analog aviation instruments. Switches are provided to turn on / off the
audio and sink alarms as well as a QNH knob to adjust the sea level pressure setting. The QNH knob is dragged around the outside of the instrument dial rather than "turned" for ease of use on a touch
screen.
The altitude is calculated using the barometric formula and is reasonably accurate against a mechanical altimeter up to around 10,000 feet. The variometer uses a simple scalar Kalman filter to help stabilise the needle. A future enhancement will be to implement a matrix based filter to improve the responsiveness of the varometer.
Altitude has been tested whilst soaring in sailplanes and paragliding, and is about half a second response slower than a dedicated hardware variometer but never the less provides a very usable vario.
