    Barometric reference/calibration

    Allows to setup arbitrary correspondence between altitude and pressure. Units available for setup are Meters or Feet for the reference altitude/elevation and hPa (mBar) or inHg.

    Calibration options include setting altitude and corresponding to it Surface (QFE) or Mean sea-level pressure (QNH).
