INDEX
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 display 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 display box. The system also removes directional numbers and letters from the HSI.

SVT TROUBLESHOOTING
SVT is intended to be used with traditional attitude, heading, obstacle, terrain, and traffic inputs. SVT is
disabled when valid attitude or heading data is not available for the display. In case of invalid SVT data, the
PFD display reverts to the standard blue-over-brown attitude display.
SVT becomes disabled without the following data resources:
-
Attitude Data
-
Heading Data
-
GPS Position Data
-
4.9 Arc-second Terrain Data
-
Obstacle Data
-
TAWS Function not Available,
in Test Mode, or Failed
-
Position of the Aircraft Exceeds
the Range of the Terrain

SVT IN REVERSIONARY MODE
SVT can be displayed on the Multifunction Display (MFD) in Reversionary Mode. If it is enabled when
switching to Reversionary Mode, SVT will take up to 30 seconds to be displayed. The standard, non-SVT
PFD display, will be shown in the interim.
UNUSUAL ATTITUDES
When the aircraft enters an unusual pitch attitude, red chevrons pointing toward the horizon warn of extreme
pitch. The chevrons are displayed on the Attitude Indicator, starting at 50˚ above and 30˚ below the horizon
line.
