Cirrus SR2x

FLIGHT INSTRUMENTS
HEADING FAILURE MODES
If the system is unable to determine the aircraft heading, but GPS-based track information is available, the
HSI displays the ground track instead of heading using HSI Track Mode. In this mode, a magenta ‘TRK’
annunciation and track readout appear on the HSI. In addition, an amber ‘HDG’ annunciation with a red X
appear above the ‘TRK’ annunciation to indicate the HSI is displaying track instead of heading.
If both the heading and track are unavailable, the HSI displays an amber ‘HDG’ annunciation with a red X
over the heading readout box. The system also removes directional numbers and letters from the HSI.
